PROSPECTUS
 
              , 1997

                              WAVETEK CORPORATION
 
OFFER TO EXCHANGE ITS 10 1/8% SENIOR SUBORDINATED NOTES DUE 2007, WHICH HAVE
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, FOR ITS OUTSTANDING 10 1/8%
SENIOR SUBORDINATED NOTES DUE 2007, WHICH WERE ISSUED AND SOLD IN A TRANSACTION
EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933.THE EXCHANGE OFFER AND
WITHDRAWAL RIGHTS WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON
             , 1997, UNLESS EXTENDED.
 
   
    Wavetek Corporation ("Wavetek" or the "Company") hereby offers, upon the
terms and subject to the conditions set forth in this Prospectus (as the same
may be amended or supplemented from time to time, the "Prospectus") and in the
accompanying Letter of Transmittal (which together constitute the "Exchange
Offer"), to exchange up to $85,000,000 aggregate principal amount of its 10 1/8%
Subordinated Notes due 2007 (the "New Notes"), which have been registered under
the Securities Act of 1933, as amended (the "Securities Act"), pursuant to a
Registration Statement (as defined herein) of which this Prospectus constitutes
a part, for a like principal amount of its outstanding 10 1/8% Senior
Subordinated Notes due 2007 (the "Old Notes" and, together with the New Notes,
the "Notes"), of which $85,000,000 aggregate principal amount is outstanding.
Pursuant to the Exchange Offer, Wavetek Corporation is also exchanging the joint
and several guarantee on a full and unconditional senior subordinated basis by
the Subsidiary Guarantors (as defined) of the Old Notes (the "Old Subsidiary
Guarantee") for a like guarantee of the New Notes (the "New Subsidiary
Guarantee" and, together with the Old Subsidiary Guarantee, the "Subsidiary
Guarantees") by the Subsidiary Guarantors. As of the date of this Prospectus,
Wavetek U.S., Inc. is the only Subsidiary Guarantor. The Company will not
receive any cash proceeds from the issuance of the New Notes offered hereby. At
June 30, 1997, the Company had approximately $114.1 million of outstanding debt
and stockholders' deficit of $73.0 million. As of June 30, 1997, the Company and
its subsidiaries had approximately $29.3 million of outstanding debt that
effectively ranks senior to the Notes and the Subsidiary Guarantees. Additional
senior debt may be incurred by the Company and its subsidiaries from time to
time, subject to certain restrictions.
    
 
    The terms of the New Notes are identical in all material respects to the
respective terms of the Old Notes, except that the New Notes have been
registered under the Securities Act and therefore will not be subject to certain
restrictions on transfer applicable to the Old Notes and will not be entitled to
registration rights. The New Notes will be issued under the indenture governing
the Old Notes. For a complete description of the terms of the New Notes, see
"Description of Notes."
 
   
    The Old Notes were originally issued and sold on June 11, 1997 in a
transaction not registered under the Securities Act in reliance upon the
exemption provided in Section 4(2) of, and Rule 144A and Regulation S under, the
Securities Act (the "Offering"). Accordingly, the Old Notes may not be offered
or sold within the United States or to United States Persons (as such terms are
defined under the Securities Act) except pursuant to an exception from, or in a
transaction not subject to, the registration requirements of the Securities Act.
The Company is making the Exchange Offer in reliance on the position of the
staff of the Division of Corporation Finance of the Securities and Exchange
Commission (the "Commission") as set forth in certain interpretive letters
addressed to third parties in other transactions. Based on these interpretations
by the staff of the Division of Corporation Finance, and subject to the two
immediately following sentences, the Company believes that New Notes issued
pursuant to the Exchange Offer in exchange for Old Notes may be offered for
resale, resold and otherwise transferred by a holder thereof (other than a
holder who is a broker-dealer) without further compliance with the registration
and prospectus delivery requirements of the Securities Act, provided that such
New Notes are acquired in the ordinary course of such holder's business and that
such holder is not participating, and has no arrangement or understanding with
any person to participate, in a distribution (within the meaning of the
Securities Act) of such New Notes. However, any holder of Old Notes who is an
"affiliate" of the Company within the meaning of Rule 405 under the Securities
Act (an "Affiliate") or who intends to participate in the Exchange Offer for the
purpose of distributing New Notes, or any broker-dealer who purchased Old Notes
from the Company to resell pursuant to Rule 144A under the Securities Act ("Rule
144A") or any other available exemption under the Securities Act, (i) will not
be able to rely on the interpretations of the staff of the Division of
Corporation Finance of the Commission set forth in the above-mentioned
interpretive letters, (ii) will not be entitled to tender such Old Notes in the
Exchange Offer and (iii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any sale or other
transfer of such Old Notes unless such sale is made pursuant to an exemption
from such requirements. In addition, as described below, if any broker-dealer (a
"Participating Broker-Dealer") holds Old Notes acquired for its own account as a
result of market-making or other trading activities and exchanges such Old Notes
for New Notes, then such Participating Broker-Dealer must deliver a prospectus
meeting the requirements of the Securities Act in connection with any resales of
such New Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a Participating Broker-Dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
Based on the position taken by the staff of the Division of Corporation Finance
of the Commission in the interpretive letters referred to above, the Company
believes that Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to the New Notes received upon exchange of such Old
Notes (other than Old Notes which represent an unsold allotment from the
original sale of the Old Notes) with the prospectus prepared for an exchange
offer so long as it contains a description of the plan of distribution with
respect to the resale of such New Notes. Accordingly, this Prospectus, as it may
be amended or supplemented from time to time, may be used by a Participating
Broker-Dealer for a period ending one year from the date on which the
Registration Statement of which this Prospectus is a part is declared effective
(subject to extension under certain limited circumstances) in connection with
resales of New Notes received in exchange for Old Notes where such Old Notes
were acquired by such Participating Broker-Dealer for its own account as a
result of market-making or other trading activities.
    
 
    The New Notes will be a new issue of securities for which there currently is
no market. The Old Notes, however, have traded on the National Association of
Securities Dealers, Inc.'s PORTAL market. To the extent that Old Notes are
tendered and accepted in the Exchange Offer, the trading market, if any, for the
Old Notes could be adversely affected. Following consummation of the Exchange
Offer, the holders of Old Notes will continue to be subject to all of the
existing restrictions upon transfer thereof and will not be entitled to any
further registration rights under the Registration Rights Agreement. See "Risk
Factors -- Consequences of Exchange and Failure to Exchange Old Notes."
 
    The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered or accepted for exchange. The Exchange Offer will
expire at 5:00 p.m., New York City time, on              , 1997, unless extended
(the "Expiration Date"). Upon the terms and subject to the conditions of the
Exchange Offer, the Company will exchange, and will issue to the Exchange Agent,
New Notes for Old Notes validly tendered and not withdrawn (pursuant to the
withdrawal rights described under "-- Withdrawal Rights") promptly after the
Expiration Date. Tenders of Old Notes may be withdrawn at any time on or prior
to the Expiration Date.
 
    SEE "RISK FACTORS" BEGINNING ON PAGE 13 FOR A DISCUSSION OF CERTAIN MATTERS
THAT SHOULD BE CONSIDERED BY HOLDERS OF OLD NOTES BEFORE TENDERING THEIR OLD
NOTES FOR THE NEW NOTES OFFERED HEREBY.

disclosures concerning the Subsidiary Guarantors are not deemed to be material
to investors.

    THE FOLLOWING SUMMARY DOES NOT PURPORT TO BE COMPLETE AND IS QUALIFIED IN
ITS ENTIRETY BY THE MORE DETAILED INFORMATION AND CONSOLIDATED FINANCIAL
STATEMENTS OF THE COMPANY AND THE UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL
DATA OF THE COMPANY INCLUDED ELSEWHERE IN THIS PROSPECTUS. EXCEPT AS OTHERWISE
SET FORTH HEREIN, REFERENCES HEREIN TO "PRO FORMA" FINANCIAL DATA OF THE COMPANY
ARE TO FINANCIAL DATA OF THE COMPANY WHICH GIVE EFFECT TO CERTAIN
RECAPITALIZATION TRANSACTIONS DESCRIBED HEREIN THAT WERE EFFECTED BY THE COMPANY
ON JUNE 11, 1997 (THE "RECAPITALIZATION TRANSACTIONS"), INCLUDING THE ISSUANCE
OF THE OLD NOTES AND THE INCURRENCE OF INDEBTEDNESS UNDER THE NEW CREDIT
AGREEMENT. THE COMPANY'S FISCAL YEAR ENDS ON SEPTEMBER 30. UNLESS THE CONTEXT
OTHERWISE REQUIRES, REFERENCES TO THE "COMPANY" OR "WAVETEK" HEREIN SHALL BE TO
WAVETEK CORPORATION AND ITS CONSOLIDATED SUBSIDIARIES.
 
                                  THE COMPANY
 
   
    Wavetek is a leading global designer, manufacturer and distributor of a
broad range of electronic test instruments, with a primary focus on
application-specific instruments for testing voice, video and data
communications equipment and networks ("Communications Test"). The Company also
designs, manufactures and distributes precision instruments to calibrate and
test electronic equipment ("Calibration Instruments") and provides repair,
upgrade and calibration services for its products on a worldwide basis
("Service"). The Company was acquired in 1991 by an investment group led by Dr.
Terence J. Gooding ("Gooding") and consummated the Recapitalization Transactions
in June 1997 with certain new equity investors. The Company has increased sales
from $58.1 million in fiscal 1992 to $151.0 million in fiscal 1996, EBITDA (as
defined) from $3.8 million in fiscal 1992 to $20.9 million in fiscal 1996 and
net income from $2.9 million in fiscal 1992 to $13.5 million in fiscal 1996 by
increasing its penetration of existing markets and by entering additional
markets through new product introductions and acquisitions. For the latest
twelve months ended June 30, 1997 ("LTM"), Wavetek had sales and EBITDA of
$154.5 million and $22.3 million, respectively. Wavetek's LTM net income was
$5.5 million after giving effect to a one-time charge of $4.3 million, net of
tax, for stock option compensation related to the Recapitalization Transactions.
    
 
    Wavetek believes it has achieved its success by: (i) focusing on the $2.5
billion Communications Test market segment of the test instrument industry,
which is expected to grow by approximately 10% per annum through 2001; (ii)
identifying changing industry trends and customer needs and successfully
introducing responsive new products on a timely basis; (iii) serving the
increasing demand for application-specific, portable field service and
maintenance equipment, which accounted for over 70% of the Company's LTM sales;
and (iv) leveraging its operations and development capabilities outside the
United States, where the Company generated 61% of its LTM sales. Wavetek
believes that its product development capabilities, product quality, breadth of
product line and geographic diversity should enable it to continue to expand its
share of existing markets and successfully enter new markets.
 
    The Company's Communications Test products, which accounted for 75% of the
Company's LTM sales, serve the cable television ("CATV"), wireless
communications ("Wireless"), telecommunications ("Telecom"), local area network
("LAN") and general purpose hand-held electronic test tools ("Test Tools")
market segments of the test instrument industry. The primary end users for the
Company's Communications Test products are service, installation and maintenance
personnel of CATV operators, wireless communications companies,
telecommunications companies and data communications equipment installers. The
Company's CATV products are used by CATV operators to diagnose and monitor CATV
systems, test cable for signal quality and leakage and ensure the proper
installation of new services such as cable modems. The Company's Wireless
products are used by wireless operators, equipment manufacturers and retailers
to test mobile phones during production, repair or at the point-of-sale and by
wireless operators and equipment manufacturers to test base stations. The
Company's Telecom products are used by telecommunications companies to install
and maintain fiber optic cable. The Company's LAN products are used by LAN
installation and service professionals to test LAN cables and connectors
("physical
 
                                       3

layer"). The Company's Test Tools products, primarily hand-held digital
multimeters ("DMMs"), are used to test a wide variety of electronic and
electrical equipment. The Company has strong competitive positions in its target
markets and believes it is the worldwide market leader in the manufacture of
CATV test equipment, the second largest supplier of hand-held DMMs and one of
the five largest manufacturers of Wireless and physical layer LAN test
equipment.
 
    The Company's Calibration Instruments products, which accounted for 17% of
the Company's LTM sales, are used in metrology, engineering and manufacturing
environments worldwide to calibrate electronic equipment and certify compliance
with international standards. The Company believes it is the second largest
global manufacturer of products used for: (i) calibrating and verifying the
accuracy of voltage measuring equipment ("Calibration Sources"); and (ii)
transferring the accuracy of voltage measurements from national standards
laboratories to industry calibration laboratories ("Transfer Standards"). The
Company's Calibration Instruments products also include high precision DMMs
("Precision DMMs"). The Company successfully competes in this market based on
its technical expertise, relationships with national laboratories and product
reputation.
 
    The Company's Service business, which accounted for 8% of the Company's LTM
sales, provides repair, upgrade and calibration services for the Company's
products through eight Wavetek service centers worldwide and an international
network of independent representatives.
 
    Wavetek has global design, manufacturing, marketing and distribution
capabilities through facilities located in the United States, the United
Kingdom, France and Germany. The Company is committed to providing high quality
manufacturing and has received or is in the process of receiving ISO 9000
certification (an international quality standard) for each of its manufacturing
facilities. In addition, Wavetek supports its broad international base of over
5,000 customers with regional sales offices in San Diego, Indianapolis, Norwich,
Paris, Munich, Vienna, Singapore, Hong Kong, Beijing and Shanghai. The Company's
products are sold through direct sales teams in the United States, the United
Kingdom, France and Germany and a global network of over 250 distributors and
independent representatives.
 
                               BUSINESS STRATEGY
 
    Wavetek believes that it has achieved its strong position in the
Communications Test and Calibration Instruments market segments by identifying
changing industry trends and customer needs, and by successfully introducing
high-quality, cost-effective, application-specific products to meet such needs
on a timely basis. The Company's business strategy is to further enhance its
strong position in these markets and to continue to increase sales and EBITDA
through the following key initiatives:
 
    - FOCUS ON THE LARGE, RAPIDLY GROWING COMMUNICATIONS TEST SEGMENT. The
      Company generated 75% of its LTM sales from Communications Test products
      and intends to continue to focus on this segment of the test instrument
      industry. Prime Data, a market research firm, expects sales in the
      Communications Test market to grow at approximately 10% per annum from
      approximately $2.5 billion in 1996 to approximately $4.0 billion in 2001.
      The Company believes that the drivers of this growth include: (i) rapidly
      changing communications technology; (ii) growing demand for personal
      communications services (including mobile phones, interactive CATV and
      internet access); and (iii) increasing worldwide investment to build or
      upgrade data and communications infrastructure. Wavetek intends to
      capitalize on this large, rapidly growing market segment through its broad
      Communications Test product portfolio, extensive international presence
      and strong market positions in CATV, Wireless and LAN.
 
    - DEVELOP APPLICATION-SPECIFIC PRODUCTS FOR TARGET MARKETS ON A TIMELY
      BASIS. Wavetek's product development strategy is to: (i) focus on
      application-specific products that are responsive to customer needs; (ii)
      minimize development time in order to address rapidly changing technology;
      and (iii) leverage design efforts by generating multiple product line
      extensions from existing product platforms. Wavetek has a history of
      successful new product introductions, including eight new
 
                                       4
<PAGE>
      products in fiscal 1996, and the Company expects to introduce
      approximately ten new products in fiscal 1997.
 
    - MEET DEMAND FOR ENHANCED PORTABLE TEST INSTRUMENTS. The Company generated
      over 70% of its LTM sales from portable field service and maintenance
      equipment and intends to continue to focus on these types of products. The
      increasing complexity of communications technology is creating demand for
      field test equipment that incorporates enhanced measurement performance.
      Furthermore, service, installation and maintenance personnel are demanding
      smaller, more portable products that enable them to service systems and
      equipment in the field rather than at a service facility. As a result of
      its product design, manufacturing and distribution strengths in portable
      test instruments, the Company believes it will continue to benefit from
      these demand trends.
 
    - LEVERAGE INTERNATIONAL OPERATIONS AND DISTRIBUTION. The Company believes
      that international capital investment in communications infrastructure has
      provided and will continue to provide growth in the worldwide
      Communications Test market. Wavetek believes it is well-positioned to
      capitalize on this growth with its substantial international operations
      that include: (i) three foreign manufacturing facilities; (ii) established
      international sales and distribution channels; and (iii) approximately 450
      employees located outside of the United States. The Company generated 61%
      of its LTM sales from customers outside the United States and believes its
      international operations should enable it to gain market share in existing
      international markets and successfully enter new markets, particularly in
      the Asia-Pacific, Eastern Europe and South America regions. Additionally,
      the Company believes that its strategic alliance formed in 1996 with
      Yokogawa Electric Corporation ("Yokogawa"), a leading Japanese process
      control and test and measurement company, coupled with the development of
      new products tailored for the Japanese market, will increase the Company's
      sales in Japan.
 
    - ENHANCE PROFITABILITY THROUGH CONTINUED IMPROVEMENT IN THE WIRELESS AND
      TELECOM BUSINESSES. Wavetek has taken measures to improve the operations
      of its Wireless and Telecom businesses, acquired in October 1994,
      including: (i) introducing new products with higher gross margins; (ii)
      rationalizing old, low margin businesses and products; (iii) reducing
      headcount; (iv) hiring new management; and (v) reducing marketing and
      selling expenses as a percentage of sales. As a result of these ongoing
      efforts, the Company has significantly improved the operating results of
      these acquired businesses. As new products with higher margins continue to
      replace older products, and as the Company makes additional cost
      improvements in its European manufacturing operations, the Company expects
      results from these businesses to continue to improve.
 
                           FINANCIAL CHARACTERISTICS
 
    The Company's business has the following financial characteristics:
 
    - DIVERSE AND GLOBAL CUSTOMER BASE. The Company has a broad international
      base of over 5,000 customers operating in a wide range of industries. In
      fiscal 1996, no customer represented more than 5% of the Company's sales,
      and the Company's top ten customers represented approximately 17% of
      sales. Customers outside the United States accounted for 61% of the
      Company's LTM sales. The Company believes that its diverse and global
      customer base should allow it to mitigate the impact of potential economic
      downturns in certain businesses or geographic areas.
 
   
    - STRONG SALES AND EBITDA GROWTH. The Company has increased sales from $58.1
      million in fiscal 1992 to $151.0 million in fiscal 1996, EBITDA from $3.8
      million in fiscal 1992 to $20.9 million in fiscal 1996 and net income from
      $2.9 million in fiscal 1992 to $13.5 million in fiscal 1996. During this
      period, the Company's EBITDA as a percentage of sales increased from 6.5%
      in fiscal 1992 to 13.9% in fiscal 1996 and the Company's net income as a
      percentage of sales increased from 4.9% in fiscal 1992 to 8.9% in fiscal
      1996. The Company believes that this performance can be attributed to: (i)
      developing application-specific products to address market needs; (ii)
      acquiring and significantly
    
 
                                       5
<PAGE>
      improving the operations of its Wireless and Telecom businesses; (iii)
      consolidating manufacturing facilities; and (iv) increasing operating
      efficiencies.
 
    - LIMITED CAPITAL EXPENDITURES. The Company's business is not capital
      intensive and its management emphasizes a disciplined approach to capital
      expenditures and working capital management. The Company's primary capital
      expenditures in the past five years have been for upgrading manufacturing
      capabilities, purchasing tooling for new products and implementing a new
      management information systems infrastructure. Annual capital expenditures
      have averaged less than 2.5% of sales over the last five fiscal years and
      have recently increased primarily as a result of investment in new
      management information systems.
 
                             CORPORATE INFORMATION
 
    The Company was founded in San Diego in 1962 and completed its initial
public offering in 1972. In June 1991, Wavetek was acquired by an investment
group led by Gooding and reorganized under a new management team, with Gooding
as Chairman and Chief Executive Officer. The Company has been privately held
since that time.
 
    Since Gooding acquired the Company, it has completed two strategic
acquisitions: (i) the Instrumentation Products Division of Beckman Industrial
("Beckman") in October 1992; and (ii) the Wireless and Telecom businesses of
Schlumberger S.A. ("Schlumberger") in October 1994. Since 1992, the Company has
divested two small non-strategic businesses and has discontinued certain
non-core products. As part of its strategy for growth in the future, Wavetek
intends to continue to evaluate the acquisition of complementary businesses that
could expand its presence in new or existing product areas or geographic markets
or create cost savings opportunities.
 
    The Company is a Delaware corporation. The Company's executive offices are
located at 11995 El Camino Real, Suite 301, San Diego, California 92130 and its
telephone number is (619) 793-2300.
 
                       THE RECAPITALIZATION TRANSACTIONS
 
    The Old Notes were originally issued in connection with the following
Recapitalization Transactions: (i) DLJ Merchant Banking Partners II, L.P. and
its affiliates ("DLJMB") and Green Equity Investors II, L.P. and its affiliates
("GEI" and, together with DLJMB, the "New Equity Investors") purchased shares of
Common Stock from the Company, representing 49.7% of the Common Stock
outstanding following the Recapitalization Transactions, for an aggregate of
$43.5 million (the "New Equity Investment"); (ii) the Company issued the Old
Notes; and (iii) the Company incurred indebtedness of $25.0 million under a five
year and six month term loan facility and entered into a five year and six month
revolving credit facility providing for borrowings up to $20.0 million (the "New
Credit Agreement"). See "Description of Other Indebtedness -- New Credit
Agreement." These proceeds were used to repurchase Common Stock from existing
stockholders for an aggregate of $152.5 million and to make cash payments upon
surrender of stock options by employees in an aggregate amount of $7.1 million.
Gooding, Yokogawa and the other existing stockholders retained 50.3% of the
shares of Common Stock outstanding following the Recapitalization Transactions.
See "The Recapitalization Transactions" and "Ownership of Capital Stock."

                                      subsidiaries. As of the date of this Prospectus,
                                      Wavetek U.S. Inc. is the only Subsidiary Guarantor.
                                      The Subsidiary Guarantees may be released under
                                      certain circumstances. See "Description of Notes --
                                      Subsidiary Guarantees."
 
Ranking.............................  The Notes are subordinated in right of payment to all
                                      existing and future Senior Debt of the Company,
                                      including borrowings under the New Credit Agreement.
                                      The Subsidiary Guarantees are subordinated in right
                                      of payment to all existing and future Senior Debt of
                                      the Subsidiary Guarantors, including guarantees of
                                      the New Credit Agreement. The Notes, the Subsidiary
                                      Guarantees and borrowings under the New Credit
                                      Agreement will be effectively subordinated to the
                                      indebtedness of the Foreign Subsidiaries. As of June
                                      30, 1997, the Company and its Subsidiary Guarantors
                                      had approximately $25.0 million of Senior Debt and
                                      the Foreign Subsidiaries had approximately $4.3
                                      million of outstanding debt, all of which effectively
                                      ranks senior to the Notes and the Subsidiary
                                      Guarantees. The Indenture permits the Company and its
                                      Subsidiaries to incur additional Indebtedness,
                                      including Senior Debt, subject to certain
                                      limitations, and prohibits the incurrence of any
                                      Indebtedness by the Company and the Subsidiary
                                      Guarantors that is senior to the Notes and the
                                      Subsidiary Guarantees, as the case may be, and
                                      subordinated to Senior Debt and Senior Debt of the
                                      Subsidiary Guarantors, as the case may be. See
                                      "Description of Notes -- Subordination," "-- Certain
                                      Covenants" and "Description of Other Indebtedness."
 
Change of Control...................  Upon the occurrence of a Change of Control, holders
                                      of the Notes will have the right to require the
                                      Company to purchase all or any part of their Notes at
                                      a price equal to 101% of the aggregate principal
                                      amount thereof, plus accrued and unpaid interest and
                                      Liquidated Damages, if any, to the date of purchase.
                                      It is possible that the Company may be prohibited
                                      from or unable to make payments due upon a Change in
                                      Control. See "Risk Factors -- Possible Inability to
                                      Purchase Notes Upon a Change in Control" and
                                      "Description of Notes -- Certain Covenants -- Change
                                      of Control."
 
Certain Covenants...................  The Indenture contains certain covenants that, among
                                      other things, limit the ability of the Company and
                                      its subsidiaries to: (i) pay dividends or make
                                      certain other Restricted Payments (as defined); (ii)
                                      incur additional Indebtedness (as defined); (iii)
                                      encumber or sell assets; (iv) enter into certain
                                      guarantees

                                      affiliates; and (vi) merge or consolidate with any
                                      other entity or to transfer or lease all or
                                      substantially all of their assets. In addition, under
                                      certain circumstances, the Company will be required
                                      to offer to purchase Notes at a price of 100% of the
                                      principal amount thereof, plus accrued and unpaid
                                      interest and Liquidated Damages, if any, to the date
                                      of purchase with the proceeds of certain Asset Sales
                                      (as defined). See "Description of Notes -- Certain
                                      Covenants."
 
Exchange Offer; Registration Rights;
  Liquidated Damages................  Pursuant to the Registration Rights Agreement, the
                                      Company agreed (i) to file a registration statement
                                      on or prior to 60 days after the Issue Date with
                                      respect to the Exchange Offer to issue the New Notes
                                      in exchange for the Old Notes and (ii) to use its
                                      best efforts to cause the Exchange Offer Registration
                                      Statement to be declared effective by the Commission
                                      on or prior to 120 days after the Issue Date. The
                                      Exchange Offer is being made to satisfy the
                                      contractual obligations of the Company under the
                                      Registration Rights Agreement. In certain
                                      circumstances, the Company will be required to
                                      provide a shelf registration statement to cover
                                      resales of the Old Notes by the holders thereof. If
                                      the Company fails to satisfy these registration
                                      obligations, it will be required to pay liquidated
                                      damages ("Liquidated Damages") to the Holders of Old
                                      Notes under certain circumstances. See "Description
                                      of Notes -- Registration Rights; Liquidated Damages."
                                      The New Notes will not be entitled to registration
                                      rights.

(1) The Company's net income for fiscal 1994, 1995 and 1996 and the nine months
    ended June 30, 1996 and 1997 was favorably impacted because the Company's
    provisions for income taxes were lower in those periods than the amounts
    calculated using statutory rates due to the utilization of certain net
    operating loss carryforwards and reductions in certain valuation allowances
    provided in prior years due to uncertainties regarding the realization of
    certain deferred tax assets. In fiscal 1996, a tax benefit of $6.2 million
    was realized due to the reductions of certain valuation allowances which
    were recorded as of the end of fiscal 1995. See Note 11 to the Company's
    Consolidated Financial Statements included elsewhere herein.
    
 
   
(2) EBITDA is operating income plus depreciation and amortization expense, stock
    option compensation related to recapitalization and provision for
    restructuring operations. The Company's definition of EBITDA is consistent
    with the definition of Consolidated Cash Flow in the Indenture. While EBITDA
    should not be construed as a substitute for income from operations, net
    income or cash flows from operating activities in analyzing the Company's
    operating performance, financial position or cash flows, the Company has
    included EBITDA because it may be used as an indicator of compliance with
    certain covenants in the Indenture and the New Credit Agreement and is
    commonly used by certain investors and analysts to analyze and compare
    companies on the basis of operating performance, leverage and liquidity and
    to determine a Company's ability to service debt. EBITDA as presented by the
    Company herein may not be comparable to similarly titled measures reported
    by other companies. In addition, the amount reported by the Company as
    EBITDA may not be fully available for management's discretionary use due to
    the Company's needs to conserve funds for debt service, capital expenditures
    and other commitments. See "Description of Notes -- Certain Covenants" and
    "-- Certain Definitions."
    
 
   
(3) In connection with the Recapitalization Transactions, the Company made cash
    payments upon the surrender of stock options by employees in an aggregate
    amount of $7.1 million. This amount is included in operating expenses for
    the nine month period ended June 30, 1997.
    
 
   
(4) In fiscal 1996, the Company initiated a plan to restructure certain
    corporate management functions, its European manufacturing, service and
    sales activities, and its San Diego manufacturing activities. The
    restructuring costs primarily include expenses for employee severance and
    closedown of certain manufacturing operations. The restructuring is expected
    to be completed during fiscal 1997.
    
 
   
(5) For purposes of computing this ratio, earnings consist of income before
    provision for income taxes plus fixed charges. Fixed charges consist of
    interest expense, amortization of deferred debt issuance costs and one-third
    of the rent expense from operating leases, which management believes is a
    reasonable approximation of the interest factor of the rent.
    
 
   
(6) See "Unaudited Pro Forma Consolidated Financial Data."
    
 
   
(7) For the nine months ended June 30, 1997 and the twelve months ended June 30,
    1997, pro forma earnings were inadequate to cover pro forma fixed charges by
    $0.6 million and $2.3 million, respectively.
    
 
   
(8) Net debt is total debt less cash and cash equivalents and short-term
    investments. As of June 30, 1997, net debt was $111.3 million.
    
 
   
(9) Cash and cash equivalents includes short-term investments of $3.0 million,
    which are comprised primarily of U.S. Treasury securities and guaranteed
    obligations of the U.S. government or its agencies with original maturities
    between 3 and 12 months.

                                  RISK FACTORS
 
   
    IN ADDITION TO THE OTHER INFORMATION SET FORTH IN THIS PROSPECTUS, BEFORE
TENDERING THEIR OLD NOTES FOR THE NEW NOTES OFFERED HEREBY, HOLDERS OF OLD NOTES
SHOULD CONSIDER CAREFULLY THE FOLLOWING MATTERS, WHICH (OTHER THAN "CONSEQUENCES
OF EXCHANGE AND FAILURE TO EXCHANGE OLD NOTES" AND "ABSENCE OF PUBLIC MARKET")
ARE GENERALLY APPLICABLE TO THE OLD NOTES AS WELL AS THE NEW NOTES.
    
 
LEVERAGE
 
   
    As a result of the Recapitalization Transactions, the Company became highly
leveraged. As of June 30, 1997, including the issuance of the Old Notes and
incurrence of Indebtedness under the New Credit Agreement, the Company had
approximately $114.1 million of outstanding debt, of which $25.0 million was
Senior Debt. In addition, the Company's foreign subsidiaries ("Foreign
Subsidiaries") had approximately $4.3 million in outstanding debt, which debt
was effectively senior to the Notes. See "Capitalization." At June 30, 1997, the
Company's total debt was $118.4 million and the Company had a total
stockholders' deficit of $73.0 million. This leverage, together with
restrictions in the New Credit Agreement and the Indenture, may limit the
Company's ability to obtain additional debt financing in the future, to
implement its business strategies, to pursue strategic acquisitions or to
respond to changing business and economic conditions. In addition, required
payments of principal and interest on the Company's debt are expected to be
financed from operating cash flow, thus limiting the availability of such cash
flow for other corporate purposes. The Company's ability to generate sufficient
cash to meet its obligations is subject to many factors, certain of which are
beyond its control, including economic conditions, competition, technological
changes and regulatory standards. In addition, the Company depends on dividends
from its operating subsidiaries to generate income to meet its debt obligations.
While the Company believes that, based on current levels of operations and
anticipated growth, its cash flow from operations, together with funds available
under its revolving credit facility under the New Credit Agreement will be
adequate to meet its obligations, there can be no assurance that its actual cash
flow will in fact be sufficient to service its debt. In the event the Company's
operating cash flow and working capital are not sufficient to fund the Company's
expenditures or to service its debt, including the Notes and borrowings under
the New Credit Agreement, the Company would be required to raise additional
funds through the sale of capital stock or assets or the refinancing of all or
part of its debt. There can be no assurance that any of these sources of funds
would be available in amounts sufficient for the Company to meet its
obligations. All current and future domestic subsidiaries of the Company
unconditionally guarantee the obligations under the New Credit Agreement. In
addition, all loans are secured by a lien on substantially all existing and
after-acquired property of the Company and its current and future domestic
subsidiaries, including a pledge of 100% of the stock of all domestic
subsidiaries of the Company, 65% of the stock of all foreign subsidiaries of the
Company and all intercompany loans from the Company to the Foreign Subsidiaries.
See "Description of Notes" and "Description of Other Indebtedness."
    
 
RANKING
 
    The Notes are subordinated in right of payment to all existing and future
Senior Debt of the Company, including borrowings under the New Credit Agreement.
The Subsidiary Guarantees are subordinated in right of payment to all existing
and future Senior Debt of the Subsidiary Guarantors, including guarantees of the
New Credit Agreement. The Notes, the Subsidiary Guarantees and borrowings under
the New Credit Agreement are effectively subordinated to the indebtedness of the
Foreign Subsidiaries.
 
    As of June 30, 1997, the Company and its Subsidiary Guarantors had
approximately $25.0 million of Senior Debt and the Foreign Subsidiaries had
approximately $4.3 million of outstanding debt, all of which effectively ranks
senior to the Notes and the Subsidiary Guarantees. In the event of a bankruptcy,
liquidation, dissolution, reorganization or other winding up of the Company or
any of the Subsidiary Guarantors, the assets of the Company or the Subsidiary
Guarantors, as the case may be, will be available
 
                                       13
<PAGE>
to pay the Notes and the Subsidiary Guarantees only after all Senior Debt has
been paid in full, and there may not be sufficient assets remaining to pay
amounts due on the Notes or Subsidiary Guarantees. Additional Senior Debt may be
incurred by the Company and its subsidiaries from time to time, subject to
certain restrictions. See "Description of Notes -- Subordination," "-- Certain
Covenants" and "Description of Other Indebtedness."
 
COMPETITION
 
   
    The Company operates in markets that are highly competitive, and the Company
expects that competition will increase in the future. Some of the industries in
which the Company operates are characterized by rapid technological advances and
emerging industry standards. Failure to keep pace with technological advances
could adversely affect the Company's competitive positions and results of
operations. The Company competes primarily on the basis of technology,
performance, price, brand identity, quality, reliability, distribution and
customer service and support. To remain competitive, the Company must continue
to develop new products, periodically enhance its existing products and compete
effectively in the areas described above. Although the Company believes its
products are competitive in each of these areas, there can be no assurance that
existing or future competitors, some of which have greater financial resources
than the Company, will not introduce comparable or superior products
incorporating more advanced technology at lower prices. The Company's
competitors are numerous, ranging from some of the world's largest corporations
to many relatively small and highly specialized firms. Although no single
company competes in all of the Company's product markets, some of the major
competitors which compete in the individual product markets include Anritsu
Corporation, Fluke Corporation, Hewlett-Packard Company, Microtest, Inc., Rhode
& Schwartz, Inc. and Tektronix, Inc. Some of these competitors have more
extensive engineering, manufacturing and marketing capabilities and
substantially greater financial, technological and personnel resources than the
Company. See "Business -- Competition."
    
 
DEPENDENCE ON NEW PRODUCTS AND TECHNOLOGICAL CHANGE
 
   
    The communications industry is characterized by large communications service
providers competing with opposing technologies, some but not all of which are
served by the Company's equipment. To the extent that certain of these opposing
technologies are in direct competition and some communications service providers
will gain at the expense of others, the markets for the Company's products may
be affected adversely if those technologies not served by the Company are more
successful. Such changes in market demand may require the Company to develop new
products or expand into new markets or technologies. Wavetek has a history of
successful new product introductions, including eight new products in fiscal
1996, and the Company expects to introduce approximately ten new products in
fiscal 1997. While the Company is currently evaluating a number of potential new
products, some of which will address emerging technologies, there can be no
assurance that these products will be successful or profitable. The Company
typically spends 8-10% of total sales revenue in its new product development
activities.
    
 
    The Company participates in markets where timely introduction of new
products is critical to the success and market acceptance of the products. The
Company's new product development programs are subject to delays due to
unforeseen complexities in the design of the products that arise during the
development process. When encountered, these complexities may cause delays in
product introductions or costly design modifications which could have a material
adverse impact on the Company.
 
   
    The typical life cycle of the Company's products ranges from three years to
ten years, and averages approximately five years. The Company plans the timing
of its new product introductions to take into consideration the impact that such
introductions will have on the life cycles of its existing products and to
mitigate the Company's exposure to loss from excess or obsolete inventory
related to products at the end of their life cycles and exposure to lost
revenues from declining products for which no new or replacement
    
 
                                       14
<PAGE>
   
products are available. The Company does not have any material exposure to
excess or obsolete inventories or lost revenues at the present time, but there
can be no assurance that the Company will continue to be successful in managing
such risks. See "Business -- Product Development."
    
 
DEPENDENCE ON PROPRIETARY RIGHTS
 
    The Company's success and ability to compete depends in part upon protecting
its proprietary technology. There can be no assurance that the steps taken by
the Company will be adequate to deter misappropriation or independent
third-party development of its technology or that its intellectual property
rights can be successfully enforced or defended if challenged. Given the rapid
development of technology, there can be no assurance that certain aspects of the
Company's products do not or will not infringe upon the existing or future
proprietary rights of others or that, if licenses or rights are required to
avoid infringement, such licenses or rights could be obtained or obtained on
terms that would not have a material adverse effect on the Company. See
"Business -- Intellectual Property."
 
    The Company has been notified by two competitors that they believe that
certain of the Company's CATV products, including in one case, its Stealth line
of products, infringe patents that have been issued to each of them. The Company
has investigated or is currently investigating the validity of those two claims.
Neither competitor has commenced litigation against the Company and, in each
case, the Company has been engaged in an exchange of correspondence with the
patent owner regarding the substance of the claims of infringement. Based upon
its investigation to date, the Company believes that both of these claims can be
resolved in a manner that will not have a material adverse impact on the
Company. However, there can be no assurance that either or both of these
competitors will not initiate litigation against the Company and may not prevail
in such litigation. To the extent that the Company does not prevail in any such
litigation or either or both of these claims are proven, the Company could be
required to: (i) redesign existing or future products so that they do not use
the rights covered by the patent rights in question; (ii) negotiate licenses or
other rights to use those patent rights; (iii) withdraw existing products or not
introduce future products that are covered by those patent rights; or (iv) pay
damages for any past infringement, any and all of which could have a material
adverse impact on the Company.
 
    The Company is also a defendant in a litigation alleging that the design of
certain models of hand-held DMMs formerly sold by the Company violated the trade
dress rights of another competitor and in a recently filed patent infringement
litigation involving certain limited CATV products. The Company does not believe
that the likely outcome of either action will have a material adverse impact on
the Company or its ability to develop new products. See "Business -- Legal
Proceedings."
 
RELIANCE ON SUPPLIERS
 
   
    A portion of the Company's manufacturing operations is dependent on the
ability of suppliers to deliver completed products, integral sub-assemblies or
components in time to meet critical distribution and manufacturing schedules.
The Company periodically experiences constrained supply of certain component
parts in some product lines as a result of strong demand in those product lines
as well as strong demand in the industry. Continued constraints may adversely
affect the Company's operating results until alternate sourcing is developed.
    
 
    Although the Company attempts to use common, multi-source components
throughout its design, certain technological requirements may necessitate the
use of single-source, unique components. The Company attempts to minimize its
exposures on these components through careful vendor qualification and
purchasing, though risk exists that these parts may become obsolete,
necessitating re-design or withdrawal of product from the market. See "Business
- -- Manufacturing."
 
                                       15
<PAGE>
RELIANCE ON DISTRIBUTION CHANNELS
 
    Changing industry practices and customer preferences require the Company to
expand into new distribution channels. As more of the Company's products are
distributed through distributors and independent representatives, these channels
become more critical to the Company's success. Some of these distributors are
thinly capitalized and may be unable to withstand changes in business
conditions. The Company's financial results could be adversely affected in the
event that the financial condition of these distributors weakens. See "Business
- -- Sales and Distribution."
 
FACTORS AFFECTING CATV SALES
 
    Demand for test equipment for CATV networks has historically depended
primarily upon capital spending cycles by CATV operators for constructing,
rebuilding, upgrading and maintaining their systems. Sales of the Company's CATV
products accounted for approximately 28% of the Company's LTM sales. Such
capital spending by CATV operators is affected by a variety of factors including
general economic conditions, access by CATV operators to financing, changes in
governmental regulation of the CATV industry, competitive pressures, advances in
technology and alternatives to CATV. Over the last year, certain CATV operators
in the United States, including Tele-Communications, Inc. ("TCI"), one of the
Company's largest customers in fiscal 1996, have begun to slow down their
equipment spending. There can be no assurance that capital spending by CATV
operators will not be further reduced in the future, adversely affecting the
demand for the Company's CATV products.
 
PERIODIC FLUCTUATIONS
 
   
    The Company's LTM sales occurred in the following percentages in each of the
last four quarters: 23% for the quarter ended September 30, 1996; 27% for the
quarter ended December 31, 1996; 26% for the quarter ended March 31, 1997; and
24% for the quarter ended June 30, 1997. A variety of factors may cause
period-to-period fluctuations in the operating results of the Company. Such
factors include, but are not limited to, product mix, European summer holidays
and other seasonal influences, competitive pricing pressures, materials costs,
currency fluctuations, revenue and expenses related to new products and
enhancements of existing products, as well as delays in customer purchases in
anticipation of the introduction of new products or product enhancements by the
Company or its competitors. The majority of the Company's revenues in each
quarter results from orders received in that quarter. As a result, the Company
establishes its production, inventory and operating expenditure levels based on
anticipated revenue levels. Thus, if sales do not occur when expected,
expenditure levels could be disproportionately high and operating results for
that quarter, and potentially future quarters, would be adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Periodic Fluctuations."
    
 
INTERNATIONAL SALES AND REGULATORY STANDARDS
 
    Customers outside of the United States accounted for approximately 61% of
the Company's LTM sales. The Company expects that international sales will
continue to represent a significant percentage of its total sales in the future.
The communications industry is characterized by proprietary standards that vary
from region to region around the world and may evolve rapidly with time, in a
divergent manner from region to region. Several of the Company's product lines
address technologies where meeting current global standards, as well as changes
in those standards, is critical to competing successfully in the market. As the
number of such competing standards grows, the Company may find that is does not
have adequate resources to maintain products which address all significant
standards, resulting in an adverse effect on the Company. The Company's
international business may be affected by changes in demand resulting from
fluctuations in currency exchange rates as well as other risks such as tariff
regulations and difficulties in obtaining export licenses. In addition, the
ability of certain of the Company's customers to access the currencies in which
the Company sells its products may have an adverse effect on their ability to
purchase
 
                                       16
<PAGE>
   
the Company's products. The Company periodically uses forward exchange contracts
to hedge certain transactions denominated in foreign currencies. No such
contracts are entered for speculative purposes. At June 30, 1997, the Company
had no material forward exchange contracts outstanding. See "Business -- Sales
and Distribution" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's success depends upon the continued contributions of its
officers and key personnel, many of whom, including Gooding, the Company's
Chairman and Chief Executive Officer, and Derek T. Morikawa ("Morikawa"), the
Company's President and Chief Operating Officer, would be difficult to replace.
Although the Company has entered into executive severance agreements with such
officers in connection with the Recapitalization Transactions, the loss of
either could have a material adverse effect on the Company. The Company's
continued growth depends on its ability to attract and retain skilled employees.
See "Management."
 
VOTING CONTROL BY OFFICERS, DIRECTORS AND AFFILIATES
 
   
    DLJMB, Gooding and GEI beneficially own 34.3%, 31.3% and 15.4%,
respectively, of the outstanding shares of Common Stock. Accordingly, together,
DLJMB, Gooding and GEI have the ability to elect all of the Company's directors,
and to control corporate actions requiring stockholder approval. Such
concentration of ownership may have the effect of delaying, deferring or
preventing a change in control of the Company. In addition, all of the
stockholders of the Company have entered into a stockholders agreement (the
"Stockholders Agreement") with respect to election of directors, transfer
restrictions on shares of Common Stock, rights of first offer for the sale of
shares and certain other matters. See "The Recapitalization Transactions,"
"Management -- Executive Officers and Directors," "Ownership of Capital Stock"
and "Certain Relationships and Related Transactions."
    
 
FRAUDULENT CONVEYANCE MATTERS
 
    Various fraudulent conveyance laws enacted for the protection of creditors
may apply to the incurrence of indebtedness by the Company in the
Recapitalization Transactions, including the issuance of the Old Notes and the
Subsidiary Guarantees. To the extent that a court were to find that (x) such
indebtedness or guarantees were incurred by the Company or a Subsidiary
Guarantor with intent to hinder, delay or defraud any present or future creditor
or the Company or the Subsidiary Guarantor contemplated insolvency with a design
to prefer one or more creditors to the exclusion in whole or in part of others
or (y) the Company or the Subsidiary Guarantor did not receive fair
consideration or reasonably equivalent value for issuing such indebtedness or
guarantee and the Company or the Subsidiary Guarantor (i) was insolvent, (ii)
was rendered insolvent by reason of such issuance, (iii) was engaged or about to
engage in a business or transaction for which the remaining assets of the
Company or Subsidiary Guarantor constituted unreasonably small capital to carry
on its business or (iv) intended to incur, or believed that it would incur,
debts beyond its ability to pay such debts as they matured, the court could
avoid or subordinate the Notes or the Subsidiary Guarantee in favor of the
Company's or the Subsidiary Guarantor's creditors. Among other things, a legal
challenge of the Notes or a Subsidiary Guarantee may focus on the benefits, if
any, realized by the Company or the Subsidiary Guarantor as a result of the
Company's issuance of the Notes or the Subsidiary Guarantor's issuance of its
Subsidiary Guarantee.
 
    The Indenture contains a savings clause, which generally limits the
obligations of any Subsidiary Guarantor under its Subsidiary Guarantee to the
maximum amount as will, after giving effect to all of the liabilities of such
Subsidiary Guarantor, result in such obligations not constituting a fraudulent
conveyance. To the extent any Subsidiary Guarantee was avoided or limited as a
fraudulent conveyance or held unenforceable for any other reason, holders of the
Notes would cease to have any claim against such Subsidiary Guarantor and would
be creditors solely of Wavetek Corporation. In such event, the claims of
 
                                       17
<PAGE>
holders of the Notes against such Subsidiary Guarantor would be subject to the
prior payment of all liabilities (including trade payables) of such Subsidiary
Guarantor. There can be no assurance that, after providing for all prior claims,
there would be sufficient assets to satisfy the claims of the holders of the
Notes relating to any avoided portion of the Subsidiary Guarantees.
 
   
    The measure of insolvency for the purposes of the foregoing considerations
will vary depending upon the law applied in any such proceeding. Generally,
however, a company may be considered insolvent if the sum of its debts,
including contingent liabilities, is greater than the fair marketable value of
all of its assets at a fair valuation or if the present fair marketable value of
its assets is less than the amount that would be required to pay its probable
liability on its existing debts, including contingent liabilities, as they
become absolute and mature. Based upon the Company's knowledge of its business
and strategy and its financial condition and results of operations, the Company
believes that the Notes and the Subsidiary Guarantees are being incurred for
proper purposes and in good faith and that the Company and the Subsidiary
Guarantors are solvent and will continue to be solvent after issuing the Notes
and the Subsidiary Guarantees, will have sufficient capital for carrying on
their respective businesses after such issuance and will be able to pay their
debts as they mature. There can be no assurance, however, that a court passing
on such standards would agree with such beliefs. See "Description of Notes --
Subsidiary Guarantees."
    
 
FOREIGN SUBSIDIARIES
 
    The Indenture and the New Credit Agreement permit the Company and its
subsidiaries to make investments in, and intercompany loans to, the Foreign
Subsidiaries. Payments to the Company or its other subsidiaries by such Foreign
Subsidiaries, including the payment of dividends, redemption of capital stock or
repayment of such intercompany loans, may be restricted by the credit agreements
of the Foreign Subsidiaries. The Company's inability to make such payments or
repatriate such monies may have a material adverse effect on the Company's
ability to pay interest or Liquidated Damages, if any, on or principal of the
Notes when due. In addition, in the event of a liquidation, bankruptcy or
reorganization of the Company, the right of the Company to collect amounts owed
to it by the Foreign Subsidiaries may be similarly restricted. All intercompany
loans from the Company to the Foreign Subsidiaries are pledged to the lenders
under the New Credit Agreement.
 
POSSIBLE INABILITY TO PURCHASE NOTES UPON A CHANGE OF CONTROL
 
   
    The New Credit Agreement prohibits the Company from purchasing Notes and
also provides that certain change of control events with respect to the Company
would constitute a default thereunder. Any future credit agreements or other
agreements relating to Senior Debt to which the Company becomes a party may
contain similar restrictions and provisions. In the event a Change of Control
occurs at a time when the Company is prohibited from purchasing Notes, the
Company could seek the consent of its lenders to the purchase of Notes or could
attempt to refinance the borrowings that contain such prohibition. If the
Company does not obtain such a consent or repay such borrowings, the Company
will remain prohibited from purchasing Notes. In addition, it is possible that
the Company will not have sufficient funds to make the payments due upon a
Change of Control. In either such case, the Company's failure to purchase
tendered Notes would constitute an event of default under the Indenture which
would, in turn, constitute a default under the New Credit Agreement. In such
circumstances, the subordination provisions in the Indenture would likely
restrict payments to the holders of Notes. See "Description of Notes -- Certain
Covenants -- Change of Control" and "Description of Other Indebtedness -- New
Credit Agreement."
    
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
    There is no active trading market for the Notes and there can be no
assurance as to the liquidity of any markets that may develop for the Notes, the
ability of holders of the Notes to sell their Notes, or the price at which
holders would be able to sell their Notes. Future trading prices of the Notes
will depend on
 
                                       18
<PAGE>
many factors, including, among other things, prevailing interest rates, the
Company's operating results and the market for similar securities. The Initial
Purchaser has advised the Company that it currently intends to make a market in
the Notes. However, the Initial Purchaser is not obligated to do so and any
market-making may be discontinued at any time without notice. In addition, such
market-making activity will be subject to the limits imposed by the Securities
Act and the Exchange Act. The Company does not intend to apply for listing of
the Notes on any securities exchange.
 
   
CONSEQUENCES OF EXCHANGE AND FAILURE TO EXCHANGE OLD NOTES
    
 
   
    Holders of Old Notes who do not exchange their Old Notes for New Notes
pursuant to the Exchange Offer will continue to be subject to all of the
restrictions on transfer of such Old Notes as set forth in the legend thereon as
a consequence of the issuance of the Old Notes pursuant to exemptions from, or
in transactions not subject to, the registration requirements of the Securities
Act and applicable state securities laws. In general, the Old Notes may not be
offered or sold within the United States or to United States Persons (as such
terms are defined under the Securities Act) except pursuant to an exemption
from, or in a transaction not subject to, the registration requirements of the
Securities Act. The Company does not intend to register the Old Notes under the
Securities Act, and such Old Notes will not be entitled to any further
registration rights under the Registration Rights Agreement. In addition, any
holder of Old Notes who tenders in the Exchange Offer for the purpose of
participating in a distribution of the Exchange Notes may be deemed to have
received restricted securities and, if so, will be required to comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction. To the extent Old Notes are tendered and
accepted in the Exchange Offer, the trading market, if any, for the Old Notes
could be adversely affected. See "The Exchange Offer," "Description of the Notes
- -- Registration Covenant; Exchange Offer" and "Plan of Distribution."
    
 
                                       19
<PAGE>
                       THE RECAPITALIZATION TRANSACTIONS
 
    The Old Notes were originally issued in connection with the following
Recapitalization Transactions: (i) the New Equity Investors purchased shares of
Common Stock from the Company, representing 49.7% of the Common Stock
outstanding following the Recapitalization Transactions, for an aggregate of
$43.5 million; (ii) the Company issued the Old Notes; and (iii) the Company
incurred indebtedness under the New Credit Agreement of approximately $25.0
million under a five year and six month term loan facility and entered into a
five year and six month revolving credit facility providing for borrowings up to
$20.0 million. See "Description of Other Indebtedness -- New Credit Agreement."
These proceeds were used to repurchase shares of Common Stock and Class B Common
Stock from existing stockholders for an aggregate of $152.5 million. All of the
outstanding Class B Common Stock were repurchased and retired, leaving only
Common Stock outstanding. An amendment to the Company's Certificate of
Incorporation was filed, eliminating the two classes of common stock in favor of
one class with identical rights, preferences and privileges, and effecting a 10
for 1 stock split. Gooding, Yokogawa and certain other existing stockholders
retained 50.3% of the Common Stock outstanding following the Recapitalization
Transactions. See "Ownership of Capital Stock."
 
                                USE OF PROCEEDS
 
    The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. The proceeds to the Company from the Old Notes, together
with the other sources of funds in the Recapitalization Transactions, were used
to: (i) repurchase shares of Common Stock and Class B Common Stock from existing
stockholders; (ii) make cash payments upon surrender of stock options; and (iii)
pay fees and expenses of the Recapitalization Transactions. See "The
Recapitalization Transactions" and "Capitalization."
 
                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    In connection with the sale of the Old Notes, the Company and the Initial
Purchaser entered into the Registration Rights Agreement, pursuant to which the
Company agreed to file and to use its best efforts to cause to be declared
effective by the Commission a registration statement with respect to the
exchange of the Old Notes for New Notes with terms identical in all material
respects to the terms of the Old Notes. See "Description of Notes--Registration
Rights; Liquidated Damages."
 
    The Exchange Offer is being made to satisfy the contractual obligations of
the Company under the Registration Rights Agreement. The terms of the New Notes
are identical in all material respects to the respective terms of the Old Notes,
except that the New Notes have been registered under the Securities Act and
therefore will not be subject to certain restrictions on transfer applicable to
the Old Notes and will not be entitled to registration rights.
 
    Unless the context requires otherwise, the term "holder" with respect to the
Exchange Offer means any person in whose name the Old Notes are registered on
the books of the Company or any other person who has obtained a properly
completed bond power from the registered holder, or any person whose Old Notes
are held of record by Cede & Co. who desires to deliver such Old Notes by
book-entry transfer at The Depository Trust Company ("DTC").
 
    Pursuant to the Exchange Offer, the Company will exchange as soon as
practicable after the date hereof the Old Subsidiary Guarantee for the New
Subsidiary Guarantee. The New Subsidiary Guarantee has been registered under the
Securities Act.
 
                                       20

TERMS OF EXCHANGE
 
    The Company hereby offers, upon the terms and subject to the conditions set
forth in this Prospectus and in the accompanying Letter of Transmittal, to
exchange up to $85,000,000 aggregate principal amount of New Notes for a like
aggregate principal amount of Old Notes properly tendered on or prior to the
Expiration Date and not properly withdrawn in accordance with the procedures
described below. The Company will issue, promptly after the Expiration Date, an
aggregate principal amount of up to $85,000,000 of New Notes in exchange for a
like principal amount of outstanding Old Notes tendered and accepted in
connection with the Exchange Offer. The terms of the New Notes are identical in
all material respects to the terms of the Old Notes for which they may be
exchanged pursuant to the Exchange Offer, except that (i) the New Notes will
generally be freely transferable by holders thereof and (ii) the holders of the
New Notes will not be entitled to registration rights under the Registration
Rights Agreement. See "Description of Notes -- Registration Rights; Liquidated
Damages." The New Notes will evidence the same debt as the Old Notes and will be
entitled to the benefits of the Indenture. See "Description of Notes."
 
    The Exchange Offer is not conditioned upon any minimum principal amount of
Old Notes being tendered. As of the date of this Prospectus, $85,000,000
aggregate principal amount of Old Notes is outstanding.
 
    Old Notes which are not tendered for or are tendered but not accepted in
connection with the Exchange Offer will remain outstanding and be entitled to
the benefits of the Indenture, but will not be entitled to any further
registration rights under the Registration Rights Agreement. See "Risk Factors
Consequences of a Failure to Exchange Old Notes" and "Description of Old Notes."
 
    If any tendered Old Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, any such unaccepted Old Notes will be returned, without expense, to
the tendering holder thereof promptly after the Expiration Date.
 
    Holders who tender Old Notes in connection with the Exchange Offer will not
be required to pay brokerage commissions or fees or, subject to the instructions
in the Letter of Transmittal, transfer taxes with respect to the exchange of Old
Notes in connection with the Exchange Offer. The Company will pay all charges
and expenses, other than certain applicable taxes described below, in connection
with the Exchange Offer. See "-- Fees and Expenses."
 
    THE BOARD OF DIRECTORS OF THE COMPANY MAKES NO RECOMMENDATIONS TO HOLDERS OF
OLD NOTES AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING ALL OR ANY PORTION
OF THEIR OLD NOTES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION, NO ONE HAS BEEN
AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION. HOLDERS OF OLD NOTES MUST MAKE THEIR
OWN DECISION WHETHER TO TENDER PURSUANT TO THE EXCHANGE OFFER AND, IF SO, THE
AGGREGATE AMOUNT OF OLD NOTES TO TENDER AFTER READING THIS PROSPECTUS AND THE
LETTER OF TRANSMITTAL AND CONSULTING WITH THEIR ADVISERS, IF ANY, BASED ON THEIR
OWN FINANCIAL POSITION AND REQUIREMENTS.
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The Exchange Officer will expire on the Expiration Date. The term
"Expiration Date" means 5:00 p.m., New York City time, on ________, 1997, unless
the Exchange Offer is extended by the Company (in which case the term
"Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended).
 
    The Company expressly reserves the right in its sole discretion, subject to
applicable law, at any time and from time to time, (i) to delay the acceptance
of the Old Notes for exchange, (ii) to terminate the Exchange Offer (whether or
not any Old Notes have theretofore been accepted for exchange) if the
 
                                       21
<PAGE>
Company determines, in its sole discretion, that any of the events or conditions
referred to under " Conditions to the Exchange Offer" have occurred or exist,
(iii) to extend the Expiration Date of the Exchange Offer and retain all Old
Notes tendered pursuant to the Exchange Offer, subject, however, to the right of
holders of Old Notes to withdraw their tendered Old Notes as described under "
Withdrawal Rights," and (iv) to waive any condition or otherwise amend the terms
of the Exchange Offer in any respect. If the Exchange Offer is amended in a
manner determined by the Company to constitute a material change, or if the
Company waives a material condition of the Exchange Offer, the Company will
promptly disclose such amendment by means of an amended or supplemented
Prospectus that will be distributed to the registered holders of the Old Notes,
and the Company will extend the Exchange Offer to the extent required by Rule
14e-1 under the Exchange Act.
 
    Any such delay in acceptance, extension, termination or amendment will be
followed promptly by oral or written notice thereof to the Exchange Agent and by
making a public announcement thereof, and such announcement in the case of an
extension will be made no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date. Without limiting
the manner in which the Company may choose to make any public announcement and
subject to applicable law, the Company shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
issuing a release to an appropriate news agency.
 
ACCEPTANCE FOR EXCHANGE AND ISSUANCE OF NEW NOTES
 
    Upon the terms and subject to the conditions of the Exchange Offer, the
Company will exchange, and will issue to the Exchange Agent, New Notes for Old
Notes validly tendered and not withdrawn (pursuant to the withdrawal rights
described under "-- Withdrawal Rights") promptly after the Expiration Date.
 
    In all cases, delivery of New Notes in exchange for Old Notes tendered and
accepted for exchange pursuant to the Exchange Offer will be made only after
timely receipt by the Exchange Agent of (i) Old Notes or a book-entry
confirmation of a book-entry transfer of Old Notes into the Exchange Agent's
account at DTC, including an Agent's Message if the tendering holder has not
delivered a Letter of Transmittal, (ii) the Letter of Transmittal (or facsimile
thereof), properly completed and duly executed, with any required signature
guarantees or (in the case of a book-entry transfer) an Agent's Message in lieu
of the Letter of Transmittal, and (iii) any other documents required by the
Letter of Transmittal.
 
    The term "book-entry confirmation" means a timely confirmation of a
book-entry transfer of Old Notes into the Exchange Agent's account at DTC. The
term "Agent's Message" means a message, transmitted by DTC to and received by
the Exchange Agent and forming a part of a book-entry confirmation, which states
that DTC has received an express acknowledgment from the tendering participant,
which acknowledgment states that such participant has received and agrees to be
bound by the Letter of Transmittal and that the Company may enforce such Letter
of Transmittal against such participant.
 
    Subject to the terms and conditions of the Exchange Offer, the Company will
be deemed to have accepted for exchange, and thereby exchanged, Old Notes
validly tendered and not withdrawn as, if and when the Company gives oral or
written notice to the Exchange Agent of the Company's acceptance of such Old
Notes for exchange pursuant to the Exchange Offer. The Exchange Agent will act
as agent for the Company for the purpose of receiving tenders of Old Notes,
Letters of Transmittal and related documents, and as agent for tendering holders
for the purpose of receiving Old Notes, Letters of Transmittal and related
documents and transmitting New Notes to validly tendering holders. Such exchange
will be made promptly after the Expiration Date. If for any reason whatsoever,
acceptance for exchange or the exchange of any Old Notes tendered pursuant to
the Exchange Offer is delayed (whether before or after the Company's acceptance
for exchange of Old Notes) or the Company extends the Exchange Offer or is
unable to accept for exchange or exchange Old Notes tendered pursuant to the
Exchange Offer, then, without prejudice to the Company's rights set forth
herein, the Exchange Agent may, nevertheless, on
 
                                       22
<PAGE>
behalf of the Company and subject to Rule 14e-1(c) under the Exchange Act,
retain tendered Old Notes and such Old Notes may not be withdrawn except to the
extent tendering holders are entitled to withdrawal rights as described under
"-- Withdrawal Rights."
 
    Pursuant to the Letter of Transmittal or Agent's Message in lieu thereof, a
holder of Old Notes will warrant and agree in the Letter of Transmittal that it
has full power and authority to tender, exchange, sell, assign and transfer Old
Notes, that the Company will acquire good, marketable and unencumbered title to
the tendered Old Notes, free and clear of all liens, restrictions, charges and
encumbrances, and the Old Notes tendered for exchange are not subject to any
adverse claims or proxies. The holder also will warrant and agree that it will,
upon request, execute and deliver any additional documents deemed by the Company
or the Exchange Agent to be necessary or desirable to complete the exchange,
sale, assignment, and transfer of the Old Notes tendered pursuant to the
Exchange Offer.
 
PROCEDURES FOR TENDERING OLD NOTES
 
    VALID TENDER.  Except as set forth below, in order for Old Notes to be
validly tendered pursuant to the Exchange Offer, a properly completed and duly
executed Letter of Transmittal (or facsimile thereof), with any required
signature guarantees, or (in the case of a book-entry tender) an Agent's Message
in lieu of the Letter of Transmittal, and any other required documents, must be
received by the Exchange Agent at its address set forth under "-- Exchange
Agent," and either (i) tendered Old Notes must be received by the Exchange
Agent, or (ii) such Old Notes must be tendered pursuant to the procedures for
book-entry transfer set forth below and a book-entry confirmation, including an
Agent's Message if the tendering holder has not delivered a Letter of
Transmittal, must be received by the Exchange Agent, in each case on or prior to
the Expiration Date, or (iii) the guaranteed delivery procedures set forth below
must be complied with.
 
    If less than all of the Old Notes are tendered, a tendering holder should
fill in the amount of Old Notes being tendered in the appropriate box on the
Letter of Transmittal. The entire amount of Old Notes delivered to the Exchange
Agent will be deemed to have been tendered unless otherwise indicated.
 
    THE METHOD OF DELIVERY OF THE NOTES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER, AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT.
IF DELIVERY IS BY MAIL, REGISTERED MAIL, RETURN RECEIPT REQUESTED, PROPERLY
INSURED, OR AN OVERNIGHT DELIVERY SERVICE IS RECOMMENDED. IN ALL CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
    BOOK ENTRY TRANSFER.  The Exchange Agent will make a request to establish an
account with respect to the Old Notes at DTC for purposes of the Exchange Offer
within two business days after the date of this Prospectus. Any financial
institution that is a participant in DTC's book-entry transfer facility system
may make a book-entry delivery of the Old Notes by causing DTC to transfer such
Old Notes into the Exchange Agent's account at DTC in accordance with DTC's
procedures for transfers. However, although delivery of Old Notes may be
effected through book-entry transfer into the Exchange Agent's account at DTC,
the Letter of Transmittal (or facsimile thereof), properly completed and duly
executed, with any required signature guarantees, or an Agent's Message in lieu
of the Letter of Transmittal, and any other required documents, must in any case
be delivered to and received by the Exchange Agent at its address set forth
under "-- Exchange Agent" on or prior to the Expiration Date, or the guaranteed
delivery procedure set forth below must be complied with.
 
    DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.
 
                                       23
<PAGE>
    SIGNATURE GUARANTEES.  The Old Notes need not be endorsed and signature
guarantees on the Letter of Transmittal are unnecessary unless (i) an Old Note
is registered in a name other than that of the person surrendering the
certificate or (ii) such registered holder completes the box entitled "Special
Issuance Instructions" or "Special Delivery Instructions" in the Letter of
Transmittal. In the case of (i) or (ii) above, such Old Notes must be duly
endorsed or accompanied by a properly executed bond power, with the endorsement
or signature on the bond power and on the Letter of Transmittal guaranteed by a
firm or other entity identified in Rule 17Ad-15 under the Exchange Act as an
"eligible guarantor institution," including (as such terms are defined therein):
(i) a bank; (ii) a broker, dealer, municipal securities broker or dealer or
government securities broker or dealer; (iii) a credit union; (iv) a national
securities exchange, registered securities association or clearing agency; or
(v) a savings association that is a participant in a Securities Transfer
Association (an "Eligible Institution"), unless surrendered on behalf of such
Eligible Institution. See Instruction 1 to the Letter of Transmittal.
 
    GUARANTEED DELIVERY.  If a holder desires to tender Old Notes pursuant to
the Exchange Offer and the Old Notes are not immediately available or time will
not permit all required documents to reach the Exchange Agent on or before the
Expiration Date, or the procedures for book-entry transfer cannot be completed
on a timely basis, such Old Notes may nevertheless be tendered, provided that
all of the following guaranteed delivery procedures are complied with:
 
           (i) such tenders are made by or through an Eligible Institution;
 
           (ii) a properly completed and duly executed Notice of Guaranteed
       Delivery, substantially in the form accompanying the Letter of
       Transmittal, is received by the Exchange Agent on or prior to Expiration
       Date; and
 
           (iii) all of the tendered Old Notes (or a book-entry confirmation),
       in proper form for transfer, together with a properly completed and duly
       executed Letter of Transmittal (or facsimile thereof or Agent's Message
       in lieu thereof), with any required signature guarantees and any other
       documents required by the Letter of Transmittal, are received by the
       Exchange Agent within three New York Stock Exchange trading days after
       the date of execution of such Notice of Guaranteed Delivery.
 
    The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile or mail to the Exchange Agent, and must include a guarantee by an
Eligible Institution in the form set forth in such Notice.
 
    Notwithstanding any other provision hereof, the delivery of New Notes in
exchange for Old Notes tendered and accepted for exchange pursuant to the
Exchange Offer will in all cases be made only after timely receipt by the
Exchange Agent of Old Notes, or of a book-entry confirmation with respect to
such Old Notes, and a properly completed and duly executed Letter of Transmittal
(or facsimile thereof or Agent's Message in lieu thereof), together with any
required signature guarantees and any other documents required by the Letter of
Transmittal. Accordingly, the delivery of New Notes might not be made to all
tendering holders at the same time, and will depend upon when Old Notes,
book-entry confirmations with respect to Old Notes and other required documents
are received by the Exchange Agent.
 
    The Company's acceptance for exchange of Old Notes tendered pursuant to any
of the procedures described above will constitute a binding agreement between
the tendering holder and the Company upon the terms and subject to the
conditions of the Exchange Offer.
 
    DETERMINATION OF VALIDITY.  All questions as to the form of documents,
validity, eligibility (including time of receipt) and acceptance for exchange of
any tendered Old Notes will be determined by the Company, in its sole
discretion, whose determination shall be final and binding on all parties. The
Company reserves the absolute right, in its sole discretion, to reject any and
all tenders determined by it not to be in proper form or the acceptance of
which, or exchange for, may, in the view of counsel to the Company, be unlawful.
The Company also reserves the absolute right, subject to applicable law, to
waive
 
                                       24
<PAGE>
any of the conditions of the Exchange Offer as set forth under "-- Conditions to
the Exchange Offer" or any condition or irregularity in any tender of Old Notes
of any particular holder whether or not similar conditions or irregularities are
waived in the case of other holders.
 
    The Company's interpretation of the terms and conditions of the Exchange
Offer (including the Letter of Transmittal and the instructions thereto) will be
final and binding. No tender of Old Notes will be deemed to have been validly
made until all irregularities with respect to such tender have been cured or
waived. Neither the Company, any affiliates or assigns of the Company, the
Exchange Agent nor any other person shall be under any duty to give any
notification of any irregularities in tenders or incur any liability for failure
to give any such notification.
 
    If any Letter of Transmittal, endorsement, bond power, power of attorney or
any other document required by the Letter of Transmittal is signed by a trustee,
executor, administrator, guardian, attorney-in-fact, officer of a corporation or
other person acting in a fiduciary or representative capacity, such person
should so indicate when signing, and unless waived by the Company, proper
evidence satisfactory to the Company, in its sole discretion, of such person's
authority to so act must be submitted.
 
    A beneficial owner of Old Notes that are held by or registered in the name
of a broker, dealer, commercial bank, trust company or other nominee or
custodian is urged to contact such entity promptly if such beneficial holder
wishes to participate in the Exchange Offer.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
    The Letter of Transmittal contains, among other things, the following terms
and conditions, which are part of the Exchange Offer.
 
    The party tendering Old Notes for exchange (the "Transferor") exchanges,
assigns and transfers the Old Notes to the Company and irrevocably constitutes
and appoints the Exchange Agent as the Transferor's agent and attorney-in-fact
to cause the Old Notes to be delivered to the Company and transferred and to
acquire New Notes issuable upon the exchange of such tendered Old Notes, and
that, when the same are accepted for exchange, the Company will acquire good,
marketable and unencumbered title to the tendered Old Notes, free and clear of
all liens, restrictions, charges and encumbrances and not subject to any adverse
claim. The Transferor also warrants that it will, upon request, execute and
deliver any additional documents deemed by the Company to be necessary or
desirable to complete the exchange, assignment and transfer of tendered Old
Notes. The Transferor further agrees that acceptance of any tendered Old Notes
by the Company and the issuance of New Notes in exchange therefor shall
constitute performance in full by the Company of obligations under the
Registration Rights Agreement and that the Company shall have no further
obligations or liabilities thereunder except in certain limited circumstances.
All authority conferred by the Transferor will survive the death or incapacity
of the Transferor and every obligation of the Transferor shall be binding upon
the heirs, legal representatives, successors, assigns, executors and
administrators of such Transferor.
 
    By tendering Old Notes and executing the Letter of Transmittal, the
Transferor certifies that it is not an Affiliate of the Company within the
meaning of Rule 405 under the Securities Act, that it is not a broker-dealer
that owns Old Notes acquired directly from the Company or any Affiliate of the
Company, it is acquiring the New Notes offered hereby in the ordinary course of
such Transferor's business and that such Transferor has no arrangement with any
person to participate in the distribution of such New Notes.
 
WITHDRAWAL RIGHTS
 
    Except as otherwise provided herein, tenders of Old Notes may be withdrawn
at any time on or prior to the Expiration Date.
 
    In order for a withdrawal to be effective a written, telegraphic, telex or
facsimile transmission of such notice of withdrawal must be timely received by
the Exchange Agent at its address set forth under
 
                                       25
<PAGE>
"-- Exchange Agent" on or prior to the Expiration Date. Any such notice of
withdrawal must specify the name of the person who tendered the Old Notes to be
withdrawn, the aggregate principal amount of Old Notes to be withdrawn, and (if
such Old Notes have been tendered) the name of the registered holder of the Old
Notes as set forth on the Old Notes, if different from that of the person who
tendered such Old Notes. If Old Notes have been delivered or otherwise
identified to the Exchange Agent, then prior to the physical release of such Old
Notes, the tendering holder must submit the certificate numbers shown on the
particular Old Notes to be withdrawn and the signature on the notice of
withdrawal must be guaranteed by an Eligible Institution, except in the case of
Old Notes tendered for the account of an Eligible Institution. If Old Notes have
been tendered pursuant to the procedures for book-entry transfer set forth in
"-- Procedures for Tendering Old Notes," the notice of withdrawal must specify
the name and number of the account at DTC to be credited with the withdrawal of
Old Notes, in which case a notice of withdrawal will be effective if delivered
to the Exchange Agent by written, telegraphic, telex or facsimile transmission
on or prior to the Expiration Date. Withdrawals of tenders of Old Notes may not
be rescinded. Old Notes properly withdrawn will not be deemed validly tendered
for purposes of the Exchange Offer, but may be retendered at any subsequent time
on or prior to the Expiration Date by following any of the procedures described
above under "-- Procedures for Tendering Old Notes."
 
    All questions as to the validity, form and eligibility (including time of
receipt) of such withdrawal notices will be determined by the Company, in its
sole discretion, whose determination shall be final and binding on all parties.
Neither the Company, any affiliates or assigns of the Company or the Exchange
Agent nor any other person shall be under any duty to give any notification of
any irregularities in any notice of withdrawal or incur any liability for
failure to give any such notification. Any Old Notes which have been tendered
but which are withdrawn will be returned to the holder thereof promptly after
withdrawal.
 
INTEREST ON THE NEW NOTES
 
    The New Notes will bear interest from and including their respective dates
of issuance. Holders whose Old Notes are accepted for exchange will receive
accrued interest thereon to, but not including, the date of issuance of the New
Notes, such interest to be payable with the first interest payment on the New
Notes, but will not receive any payment in respect of interest on the Old Notes
accrued after the issuance of the New Notes.
 
CONDITIONS TO THE EXCHANGE OFFER
 
    Notwithstanding any other provisions of the Exchange Offer, or any extension
of the Exchange Offer, the Company will not be required to accept for exchange,
or to exchange, any Old Notes for any New Notes, and, as described below, may
terminate the Exchange Offer (whether or not any Old Notes have theretofore been
accepted for exchange) or may waive any conditions to or amend the Exchange
Offer, if any of the following conditions has occurred or exists:
 
           (a) there shall occur a change in the current interpretation by the
       staff of the Commission which permits the New Notes issued pursuant to
       the Exchange Offer in exchange for Old Notes to be offered for resale,
       resold and otherwise transferred by holders thereof (other than broker-
       dealers and any such holder which is an Affiliate) without compliance
       with the registration and prospectus delivery provisions of the
       Securities Act provided that such New Notes are acquired in the ordinary
       course of such holders' business and such holders have no arrangement or
       understanding with any person to participate in the distribution of such
       New Notes;
 
           (b) any action or proceeding shall have been instituted or threatened
       in any court or by or before any governmental agency or body with respect
       to the Exchange Offer which, in the Company's judgment, would reasonably
       be expected to impair the ability of the Company to proceed with the
       Exchange Offer;
 
                                       26
<PAGE>
           (c) any law, statute, rule or regulation shall have been adopted or
       enacted which, in the Company's judgment, would reasonably be expected to
       impair the ability of the Company to proceed with the Exchange Offer;
 
           (d) a banking moratorium shall have been declared by United States
       federal or California or New York State authorities which, in the
       Company's judgment, would reasonably be expected to impair the ability of
       the Company to proceed with the Exchange Offer;
 
           (e) trading on the New York Stock Exchange or generally in the United
       States over-the-counter market shall have been suspended by order of the
       Commission or any other governmental authority which, in the Company's
       judgment, would reasonably be expected to impair the ability of the
       Company to proceed with the Exchange Offer;
 
           (f) a stop order shall have been issued by the Commission or any
       state securities authority suspending the effectiveness of the
       Registration Statement or proceedings shall have been initiated or, to
       the knowledge of the Company, threatened for that purpose or any
       governmental approval has not been obtained, which approval the Company
       shall, in its sole discretion, deem necessary for the consummation of the
       Exchange Offer as contemplated hereby; or
 
           (g) any change, or any development involving a prospective change, in
       the business or financial affairs of the Company or any of its
       subsidiaries has occurred which, in the judgment of the Company, might
       materially impair the ability of the Company to proceed with the Exchange
       Offer.
 
    If the Company determines in its sole discretion that any of the foregoing
events or conditions has occurred or exists, the Company may, subject to
applicable law, terminate the Exchange Offer (whether or not any Old Notes have
theretofore been accepted for exchange) or may waive any such condition or
otherwise amend the terms of the Exchange Offer in any respect. If such waiver
or amendment constitutes a material change to the Exchange Offer, the Company
will promptly disclose such waiver by means of an amended or supplemented
Prospectus that will be distributed to the registered holders of the Old Notes,
and the Company will extend the Exchange Offer to the extent required by Rule
14e-1 under the Exchange Act.
 
EXCHANGE AGENT
 
    The Bank of New York has been appointed as Exchange Agent for the Exchange
Offer. Delivery of the Letters of Transmittal and any other required documents,
questions, requests for assistance, and requests for additional copies of this
Prospectus or of the Letter of Transmittal, all whether by registered or
certified mail, by hand or by overnight courier, should be directed to the
Exchange Agent as follows:
 
           The Bank of New York
 
           101 Barclay Street
           New York, NY 10286
 
           Attention: Shilpa Priveda
 
           Telephone: (212) 815-5789
 
           and if by facsimile, to (212) 815-6339
 
    Delivery to other than the above address or facsimile number will not
constitute a valid delivery.
 
FEES AND EXPENSES
 
    The Company has agreed to pay the Exchange Agent reasonable and customary
fees for its services and will reimburse it for its reasonable out-of-pocket
expenses in connection therewith. The Company will also pay brokerage houses and
other custodians, nominees and fiduciaries the reasonable out-of-pocket
 
                                       27
<PAGE>
expenses incurred by them in forwarding copies of this Prospectus and related
documents to the beneficial owners of Old Notes, and in handling or tendering
for their customers.
 
    Holders who tender their Old Notes for exchange will not be obligated to pay
any transfer taxes in connection therewith. If, however, New Notes are to be
delivered to, or are to be issued in the name of, any person other than the
registered holder of the Old Notes tendered, or if a transfer tax is imposed for
any reason other than the exchange of Old Notes in connection with the Exchange
Offer, then the amount of any such transfer taxes (whether imposed on the
registered holder or any other persons) will be payable by the tendering holder.
If satisfactory evidence of payment of such taxes or exemption therefrom is not
submitted with the Letter of Transmittal, the amount of such transfer taxes will
be billed directly to such tendering holder.
 
    The Company will not make any payment to brokers, dealers or others
soliciting acceptances of the Exchange Offer.
 
FEDERAL INCOME TAX CONSEQUENCES
 
   
    The following is a discussion of the material tax consequences of exchanging
Old Notes for New Notes in the Exchange Offer. In the opinion of Sullivan &
Cromwell, counsel to the Company, the exchange of Old Notes for New Notes in the
Exchange Offer will not be a taxable exchange for federal income tax purposes
and, accordingly, a holder will not recognize any taxable gain or loss as a
result of such exchange.
    
 
OTHER
 
    Participation in the Exchange Offer is voluntary, and holders should
carefully consider whether to accept the Exchange Offer and tender their Old
Notes. Holders of the Old Notes are urged to consult their financial and tax
advisors in making their own decisions on what action to take.
 
    As a result of the making of, and upon acceptance for exchange of all
validly tendered Old Notes pursuant to the terms of this Exchange Offer, the
Company will have satisfied its obligations under the Registration Rights
Agreement. Holders of the Old Notes who do not tender their Old Notes in the
Exchange Offer will continue to hold such Old Notes and will be entitled to all
the rights, and subject to all the limitations applicable thereto, under the
Indenture, such holders will have no further rights to registration of Old Notes
under the Registration Rights Agreement. See "Description of the Notes --
Registration Rights; Liquidated Damages." All untendered Old Notes will continue
to be subject to the restriction on transfer set forth in the Indenture. To the
extent that Old Notes are tendered and accepted in the Exchange Offer, the
trading market, if any, for the Old Notes could be adversely affected. See "Risk
Factors -- Consequences of Exchange and Failure to Exchange Old Notes."

                UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL DATA
 
   
    The following unaudited pro forma consolidated financial data are derived
from the Company's consolidated financial statements appearing elsewhere herein,
as adjusted to give effect to the Recapitalization Transactions. The unaudited
pro forma consolidated statement of income data for the fiscal year ended
September 30, 1996 and nine month periods ended June 30, 1996 and 1997 give
effect to the Recapitalization Transactions as if they had occurred on October
1, 1995. The pro forma adjustments are based upon available data and certain
assumptions that the Company believes are reasonable. The unaudited pro forma
consolidated financial data does not purport to represent what the Company's
results of operations would actually have been had the Recapitalization
Transactions in fact occurred at such prior time or to project the Company's
results of operations for any future period. The unaudited pro forma
consolidated financial data should be read in conjunction with the consolidated
financial statements of the Company and the information contained in "The
Recapitalization Transactions," "Use of Proceeds" and "Management's Discussion
and Analysis of Financial Condition and Results of Operations" included
elsewhere herein.

(2) The pro forma provision for income taxes reflects an assumed effective rate
    of 2.1%, 2.1% and 37.7% for fiscal 1996 and the nine months ended June 30,
    1996 and 1997, respectively. The effective historical tax rates for fiscal
    year 1996 and the nine months ended June 30, 1996 are lower than expected
    statutory rates due primarily to the reduction of certain deferred tax asset
    valuation allowances due to the realization of such deferred tax assets
    becoming more likely than not. The pro forma effective tax rates for the
    periods presented differ from the historical effective tax rate because the
    pro forma adjustment to interest expense would have resulted in a lower
    reduction in the deferred tax valuation allowance available to the Company.
 
(3) The Company recorded a charge of $7,061 in June 1997 related to its cash
    payments to certain employees in exchange for their surrender of stock
    options in connection with the Recapitalization Transactions. This
    non-recurring expense, and a related non-recurring income tax benefit of
    $2,779, are not reflected in the pro forma income statement data for fiscal
    1996 or the nine months ended June 30, 1996.
 
   
(4) EBITDA is $20,933 for fiscal 1996 and $16,988 and $18,327 for the nine
    months ended June 30, 1996 and 1997, respectively. The pro forma adjustments
    noted above result in no adjustments to the amount of EBITDA reported for
    any period presented. EBITDA is operating income plus depreciation and
    amortization expense, stock option compensation related to recapitalization
    and provision for restructuring operations. The Company's definition of
    EBITDA is consistent with the definition of Consolidated Cash Flow in the
    Indenture. While EBITDA should not be construed as a substitute for income
    from operations, net income or cash flows from operating activities in
    analyzing the Company's operating performance, financial position or cash
    flows, the Company has included EBITDA because it may be used as an
    indicator of compliance with certain covenants in the Indenture and the New
    Credit Agreement and is commonly used by certain investors and analysts to
    analyze and compare companies on the basis of operating performance,
    leverage and liquidity and to determine a Company's ability to service debt.
    EBITDA as presented by the Company herein may not be comparable to similarly
    titled measures reported by other companies. In addition, the amount
    reported by the Company as EBITDA may not be fully available for
    management's discretionary use due to the Company's needs to conserve funds
    for debt service, capital expenditures and other commitments. See
    "Description of Notes -- Certain Covenants" and "-- Certain Definitions."

(5) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of income before provision for income taxes plus fixed charges.
    Fixed charges consist of interest expense, including amortization of
    deferred debt issuance costs, and one-third of the rent expense from
    operating leases, which management believes is a reasonable approximation of
    the interest factor of the rent. The actual and pro forma ratios of earnings
    to fixed charges are as follows:

(1) In connection with the Recapitalization Transactions, the Company made cash
    payments upon the surrender of stock options by employees in an aggregate
    amount of $7.1 million. This amount is included in operating expenses for
    the nine month period ended June 30, 1997.
 
(2) In fiscal 1996, the Company initiated a plan to restructure certain
    corporate management functions, its European manufacturing, service and
    sales activities and its San Diego manufacturing activities. The
    restructuring costs primarily include expenses for employee severance and
    closedown of certain manufacturing operations. The restructuring is expected
    to be completed during fiscal 1997.
 
   
(3) The Company's net income for fiscal 1992, 1993, 1994, 1995 and 1996 and the
    nine months ended June 30, 1996 and 1997 was favorably impacted because the
    Company's provisions for income taxes were lower in those periods than the
    amounts calculated using statutory rates due to the utilization of certain
    net operating loss carryforwards and reductions in certain valuation
    allowances provided in prior years due to uncertainties regarding the
    realization of certain deferred tax assets. In fiscal 1996, a tax benefit of
    $6.2 million was realized due to the reductions of certain valuation
    allowances which were recorded as of the end of fiscal 1995. See Note 11 to
    the Company's Consolidated Financial Statements included elsewhere herein.
    
 
   
(4) EBITDA is operating income plus depreciation and amortization expense, stock
    option compensation related to recapitalization and provision for
    restructuring operations. The Company's definition of EBITDA is consistent
    with the definition of Consolidated Cash Flow in the Indenture. While EBITDA
    should not be construed as a substitute for income from operations, net
    income or cash flows from operating activities in analyzing the Company's
    operating performance, financial position or cash flows, the Company has
    included EBITDA because it may be viewed as an indicator of compliance with
    certain covenants in the Indenture and the New Credit Agreement and is
    commonly used by certain investors and analysts to analyze and compare
    companies on the basis of operating performance, leverage and liquidity and
    to determine a Company's ability to service debt. EBITDA as presented by the
    Company herein may not be comparable to similarly titled measures reported
    by other companies. In addition, the amount reported by the Company as
    EBITDA may not be fully available for management's discretionary use due to
    the Company's needs to conserve funds for debt service, capital expenditures
    and other commitments. See "Description of Notes -- Certain Covenants" and
    "-- Certain Definitions."
    
 
   
(5) For purposes of computing this ratio, earnings consist of income before
    provision for income taxes plus fixed charges. Fixed charges consist of
    interest expense, amortization of deferred debt issuance costs and one-third
    of the rent expense from operating leases, which management believes is a
    reasonable approximation of the interest factor of the rent.
    
 
   
(6) See "Unaudited Pro Forma Consolidated Financial Data."
    
 
   
(7) For the nine months ended June 30, 1997 and the twelve months ended June 30,
    1997, pro forma earnings were inadequate to cover pro forma fixed charges by
    $0.6 million and $2.3 million, respectively.
    
 
   
(8) Net debt is total debt less cash and cash equivalents and short-term
    investments. As of June 30, 1997, net debt was $111.3 million.
    
 
   
(9) Cash and cash equivalents includes short-term investments, which are
    comprised primarily of U.S. Treasury securities and guaranteed obligations
    of the U.S. government or its agencies with original maturities between 3
    and 12 months.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    The following discussion should be read in conjunction with the Company's
consolidated financial statements and the Unaudited Pro Forma Consolidated
Financial Data of the Company included elsewhere herein.
 
OVERVIEW
 
    Wavetek is a leading global designer, manufacturer and distributor of a
broad range of electronic test instruments, with a primary focus on
application-specific instruments for testing voice, video and data
communications equipment and networks. The Company also designs, manufacturers
and distributes precision instruments to calibrate and test electronic equipment
and provides repair, upgrade and calibration services for its products on a
worldwide basis.
 
    The Company derives its revenues primarily from the sale of its products to
a broad international base of over 5,000 customers operating in a wide range of
industries. A majority of the Company's sales come from its Communications Test
product lines which serve the CATV, Wireless, Telecom, LAN and Test Tools market
segments of the test instrument industry. The Company also sells Calibration
Instruments and provides repair, upgrade and calibration services for its
products on a worldwide basis. The Company sells products that are manufactured
at its four facilities located in: (i) Indianapolis, Indiana; (ii) Norwich,
England; (iii) St. Etienne, France; and (iv) Munich, Germany. In major markets
such as the United States, England, France and Germany, the Company sells its
products to customers in their local currencies. In the rest of the world, the
Company generally sells its products to customers or local distributors in the
functional currency of the location where the products are manufactured. During
fiscal 1996, approximately 59% of the Company's sales were generated outside of
the United States and approximately 47% of the Company's sales were made in
currencies other than the United States dollar. As a result of such foreign
currency sales, the equivalent United States dollar amount of the Company's
sales is impacted by changes in foreign currency exchange rates. The Company's
ability to maintain and grow its sales depends on a variety of factors including
its ability to maintain its competitive position in areas such as technology,
performance, price, brand identity, quality, reliability, distribution and
customer service and support, and its ability to continue to introduce new
products that respond to technological change and market demand in a timely
manner.
 
    Wavetek's cost of goods sold, and its resulting gross margin, are driven
primarily by the cost of the material in its products, the cost of the labor to
manufacture such products and the overhead expenses in its facilities. In recent
years, the Company has focused on improving its gross margin by: (i)
consolidating manufacturing operations; (ii) focusing its new product
development efforts on lower-cost, easier to manufacture designs; (iii)
controlling headcount and expenses in its manufacturing facilities; and (iv)
gaining efficiencies and economies of scale in its material and component
procurement activities.
 
    The Company's operating expenses are substantially impacted by marketing and
selling activities and by research and development activities. Marketing and
selling expenses are primarily driven by: (i) sales volume, with respect to
sales force expenses and sales and commission expenses; (ii) the extent of
market research activities for new product design efforts; (iii) advertising and
trade show activities; and (iv) the number of new products launched in the
period. In recent periods, the Company has increased its spending on research
and development activities. This increase has resulted from the Company's
October 1994 acquisition of its Wireless and Telecom businesses, which had a
higher spending level than the Company's historical activities, and from a
planned increase in spending to accelerate the timing of new product
introductions. General and administrative expenses primarily include costs
associated with the Company's administrative employees, facilities and
functions. The Company incurs expenses in foreign countries primarily in the
functional currencies of such locations. As a result of the Company's
substantial

international operations, the United States dollar amount of its expenses is
impacted by changes in foreign currency exchange rates.
 
    In recent years, the Company's results of operations have been significantly
impacted by its October 1994 acquisition of its Wireless and Telecom businesses,
the Company's efforts to improve the operating results of these businesses and
by the rapid growth in sales and profitability of the Company's CATV product
lines.

NINE MONTHS ENDED JUNE 30, 1997 COMPARED TO NINE MONTHS ENDED JUNE 30, 1996
 
    SALES.  Sales in the nine months ended June 30, 1997 increased $3.5 million,
or 3.1%, to $118.7 million from $115.2 million in the comparable fiscal 1996
period. This increase was due to an increase in sales to international customers
of $5.3 million, or 7.7%, offset by a decrease of $1.7 million, or 3.7%, in
sales to customers in the United States. The Company's sales to customers
outside the United States increased to 62.2% in the nine months ended June 30,
1997 from 59.5% in the comparable fiscal 1996 period. Changes in foreign
exchange rates had an unfavorable impact on the United States dollar equivalent
of international sales in the nine months ended June 30, 1997. Sales of the
Company's Communications Test products increased $1.0 million, or 1.1%, from the
comparable fiscal 1996 period primarily as a result of an increase in
international sales partially offset by reduced domestic sales. Sales of
Calibration Instruments products increased $2.5 million, or 14.2%, from the
comparable fiscal 1996 period, due partially to changes in foreign exchange
rates and partially to higher shipments in connection with a planned reduction
in the backlog of this product line. Sales from repair, upgrade and calibration
services remained relatively constant during the nine months ended June 30,
1997, increasing $0.1 million, or 0.8%, from the comparable fiscal 1996 period.
 
    Within its Communications Test product lines, sales of the Company's CATV
and Wireless products increased in the nine months ended June 30, 1997 from the
comparable fiscal 1996 period, while sales of the Company's Telecom, LAN and
Test Tools products declined. The growth in CATV sales in the first nine months
of fiscal 1997 can be substantially attributed to the Company's continued
penetration of international markets as it continues to benefit from the
increasing international investment in CATV infrastructure. The increase in
Wireless product sales in the first nine months of fiscal 1997 is due primarily
to the shipment of a large order to a customer in Korea, offset by the impact of
the devaluation of the Deutsche mark against the United States dollar. The
Company's Telecom sales decreased during the first nine months of fiscal 1997 as
a result of reduced sales in France, including sales to one of the Company's
largest Telecom customers. Telecom sales in the first nine months of fiscal 1997
were also adversely affected by the devaluation in the French franc against the
United States dollar. Decreases in sales of LAN and Test Tools products during
the first nine months of fiscal 1997 were primarily attributable to pending
transitions to new or updated LAN and Test Tools products which are being
introduced in fiscal 1997. The Company's sales were also adversely impacted in
the first nine months of fiscal 1997 by the discontinuance of selected non-core
Communications Test products.
 
   
    GROSS MARGIN.  The Company's gross margin in the nine months ended June 30,
1997 increased $3.8 million, or 6.4%, to $63.2 million from $59.4 million in the
first nine months of fiscal 1996. Gross margin as a percentage of sales
increased to 53.3% in the first nine months of fiscal 1997 from 51.6% in the
first nine months of fiscal 1996. The increase in the gross margin percentage
during the first nine months of fiscal 1997 results from a higher proportion of
the Company's sales coming from its higher margin CATV products, offset by
reductions in the gross margin percentage achieved in its Wireless, Telecom and
Calibration Instruments product lines. Changes in foreign exchange rates had an
unfavorable impact on the United States dollar equivalent of gross margins
related to international sales denominated in foreign currencies in the nine
months ended June 30, 1997. The Company has also experienced higher gross margin
percentages in the first nine months of fiscal 1997 as a result of a more
favorable geographic mix. The decline in Wireless gross margin percentages in
the first nine months of fiscal 1997 is due primarily to a large sale of a
non-core product to a customer in Korea on which a lower than average gross
margin percentage was achieved.
    
 
    OPERATING EXPENSES.  Operating expenses in the nine months ended June 30,
1997 increased $9.4 million, or 20.9%, to $54.5 million from $45.1 million in
the comparable fiscal 1996 period. Operating expenses as a percentage of sales
increased to 45.9% in the first nine months of fiscal 1997 from 39.1% in the
first nine months of fiscal 1996. The increase in operating expenses in the
first nine months of fiscal 1997 was due to a one-time charge of $7.1 million,
or 5.9% of sales, for stock option compensation related to the Recapitalization
Transactions and an increase in spending for research and development activities
of
 
                                       38
<PAGE>
   
$2.2 million, to $11.6 million, or 9.8% of sales in the first nine months of
fiscal 1997 from $9.4 million, or 8.2% of sales in the first nine months of
fiscal 1996, in order to accelerate the timing of new product introductions. The
increase in the first nine months of fiscal 1997 was also partially due to
increased spending, as a percentage of sales, in marketing and selling
activities to 23.5% in the first nine months of fiscal 1997 from 23.3% in the
first nine months of fiscal 1996. These increases in the first nine months of
fiscal 1997 were partially offset by reduced spending in general and
administrative activities of $0.8 million to 6.6% in the first nine months of
fiscal 1997 from 7.5% in the first nine months of fiscal 1996, reflecting the
Company's ability to spread certain fixed expenses over a higher sales volume.
Changes in foreign exchange rates also had a favorable impact on the United
States dollar equivalent of operating expenses denominated in foreign currencies
in the nine months ended June 30, 1997.
    
 
    NON-OPERATING INCOME (EXPENSE).  Non-operating expense, net, in the nine
months ended June 30, 1997 increased by $0.6 million over the comparable fiscal
1996 period to $1.6 million. The Company's net interest expense increased to
$0.7 million during the nine months ended June 30, 1997 from $0.5 million in the
comparable fiscal 1996 period, reflecting additional interest expense due to the
Notes and the New Credit Agreement. In addition, in the nine months ended June
30, 1997, the Company's exchange losses from foreign currency transactions,
included in the "Other, net" caption in the Company's consolidated statements of
income, increased by $0.5 million over the comparable fiscal 1996 period.
 
   
    PROVISION FOR INCOME TAXES.  The Company's effective tax rate in the nine
months ended June 30, 1997 was 38.0%. In the nine months ended June 30, 1996,
the Company's effective tax rate was only 6.7% due to the reduction in certain
deferred tax asset valuation allowances in the amount of $6.2 million due to the
realization of such deferred tax assets becoming more likely than not. At June
30, 1997, the deferred tax assets were $4.5 million.
    
 
    NET INCOME.  As a result of the above factors, net income was $4.5 million
in the nine months ended June 30, 1997 as compared to $12.4 million in the nine
months ended June 30, 1996.
 
    EBITDA.  EBITDA was $18.3 million in the nine months ended June 30, 1997 as
compared to $17.0 million in the nine months ended June 30, 1996. EBITDA as a
percentage of sales increased to 15.4% in the first nine months of fiscal 1997
from 14.7% in the first nine months of fiscal 1996.
 
   
    RATIO OF EARNINGS TO FIXED CHARGES.  As a result of the above factors, the
ratio of earnings to fixed charges was 5.4x for the nine months ended June 30,
1997 as compared to 11.4x for the nine months ended June 30, 1996.
    
 
FISCAL YEAR ENDED SEPTEMBER 30, 1996 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1995
 
    SALES.  Sales in fiscal 1996 increased $17.4 million, or 13.0%, to $151.0
million from $133.6 million in fiscal 1995. The Company's mix of business in the
United States versus international markets remained constant at approximately
41% domestic and approximately 59% international in each of fiscal 1996 and
1995. Changes in foreign exchange rates did not have a material impact on total
sales in fiscal 1996 compared to fiscal 1995. Sales of the Company's
Communications Test products in fiscal 1996 increased $15.6 million, or 15.7%,
from fiscal 1995. Sales of Calibration Instruments products in fiscal 1996
increased by $0.7 million, or 2.8%, from fiscal 1995. Revenues from repair,
upgrade and calibration services increased $1.1 million in fiscal 1996, or
10.6%, over fiscal 1995 primarily due to increased service revenues for the
Company's Wireless and Telecom products in France and Germany.
 
    Within its Communications Test product lines, sales of the Company's CATV
products increased in fiscal 1996 as a result of the impact of new products
introduced in fiscal 1996 and 1995 and the positive impact of overall growth in
CATV markets due to infrastructure upgrading by United States CATV operators and
the rapid increase of cable subscribers and cable infrastructure development in
international markets. Sales of the Company's LAN products also increased in
fiscal 1996 as a result of the full-year effect of the Company's LANTEKPRO
family of products that were introduced mid-year in fiscal 1995.
 
                                       39
<PAGE>
These CATV and LAN increases in fiscal 1996 were offset by decreases in sales of
the Company's Test Tools products primarily due to the discontinuance of
non-core product lines and a decrease in sales of the Company's Wireless
products attributable to declines in sales of older products. The Company's
Communications Test sales were also impacted by the sale of a non-strategic
business in fiscal 1996.
 
    GROSS MARGIN.  The Company's gross margin in fiscal 1996 increased $17.7
million, or 29.0%, to $78.6 million from $61.0 million in fiscal 1995. Gross
margin as a percentage of sales increased to 52.1% in fiscal 1996 from 45.6% in
fiscal 1995. The increase in gross margin in fiscal 1996 was due to: (i) the
closing of the Company's San Diego manufacturing facility in fiscal 1996; (ii)
increased sales of higher gross margin Communications Test products; (iii) the
benefits of improved overhead absorption due to the significant increase in
volume of sales of CATV and LAN products; and (iv) reduced overhead spending in
the Company's Wireless and Telecom business areas, which were acquired in
October 1994.
 
   
    OPERATING EXPENSES.  Operating expenses in fiscal 1996 increased $8.5
million, or 15.7%, to $62.6 million from $54.1 million in fiscal 1995. Operating
expenses as a percentage of sales increased to 41.5% in fiscal 1996 from 40.4%
in fiscal 1995. The increase in operating expenses in fiscal 1996 was due to:
(i) a provision recorded by the Company of $1.8 million for the restructuring of
certain corporate management functions, its European manufacturing, service and
sales activities and San Diego manufacturing activities; and (ii) an increase in
general and administrative activities of $2.2 million, to 7.7% of sales in
fiscal 1996 from 7.0% of sales in fiscal 1995, due to higher than normal charges
in 1996 for executive recruitment and relocation and provisions for potentially
doubtful accounts receivable. Excluding the $1.8 million provision for
restructuring operations, operating expenses as a percentage of sales would have
decreased to 40.2% in fiscal 1996 from 40.4% in fiscal 1995. The increase in
fiscal 1996 was partially offset by reduced spending, as a percentage of sales,
in marketing and selling activities to 24.0% in fiscal 1996 from 24.4% in fiscal
1995 and in research and development activities to 8.6% ($12.9 million) in
fiscal 1996 from 9.1% ($12.1 million) in fiscal 1995, reflecting the Company's
efforts to reduce expenses in the Wireless and Telecom business areas it
acquired in October 1994.
    
 
    NON-OPERATING INCOME (EXPENSE).  Non-operating expense, net, in fiscal 1996
decreased to $1.6 million from $3.2 million in fiscal 1995. The Company's net
interest expense decreased to $0.6 million in fiscal 1996 from $1.1 million in
fiscal 1995, reflecting a reduction in average net borrowings. Other non-
operating expenses decreased to $1.0 million in fiscal 1996 from $2.1 million in
fiscal 1995, due primarily to a loss of $1.8 million incurred in fiscal 1995
related to the sale and leaseback financing of the Company's Indianapolis
facility. This decrease was partially offset by an increase in other expense of
$0.7 million in fiscal 1995 due primarily to certain non-recurring legal
expenses.
 
   
    PROVISION FOR INCOME TAXES.  The Company's effective tax rate in fiscal 1996
was 6.7% due to the reduction of certain deferred tax asset valuation allowances
of $6.2 million due to the realization of such deferred tax assets becoming more
likely than not, compared to a fiscal 1995 effective rate of 16.7%.
    
 
   
    NET INCOME.  As a result of the above factors, including in particular the
tax benefit in 1996, net income was $13.5 million in fiscal 1996 as compared to
$3.1 million in fiscal 1995.
    
 
    EBITDA.  EBITDA was $20.9 million in fiscal 1996 as compared to $9.9 million
in fiscal 1995. EBITDA as a percentage of sales increased to 13.9% in fiscal
1996 from 7.4% in fiscal 1995.
 
   
    RATIO OF EARNINGS TO FIXED CHARGES.  As a result of the above factors, the
ratio of earnings to fixed charges was 9.9x for fiscal 1996 as compared to 2.8x
for fiscal 1995.
    
 
FISCAL YEAR ENDED SEPTEMBER 30, 1995 COMPARED TO FISCAL YEAR ENDED SEPTEMBER 30,
  1994
 
    SALES.  Sales in fiscal 1995 increased $58.8 million, or 78.6%, to $133.6
million from $74.8 million in fiscal 1994. The Company's sales to customers
outside the United States increased to 59.5% of sales in fiscal 1995 from 42.6%
in fiscal 1994. The increases in total sales and the international portion of
total
 
                                       40
<PAGE>
sales are substantially attributable to the Company's acquisition of the
Wireless and Telecom business of Schlumberger in October 1994. Additionally,
sales of the Company's CATV products increased due to the early effects of the
overall growth in the CATV market and infrastructure spending described above,
and sales of the Company's LAN products grew due to the introduction of a new
product platform in the middle of fiscal 1995.
 
    GROSS MARGIN.  The Company's gross margin in fiscal 1995 increased $27.5
million, or 82.3%, to $61.0 million from $33.4 million in fiscal 1994. Gross
margin as a percentage of sales increased to 45.6% in fiscal 1995 from 44.7% in
fiscal 1994. The increase in margins was due to the positive effects of volume
increases in the CATV and LAN product lines, offset by the impact of lower gross
margins associated with the acquired Wireless and Telecom business.
 
   
    OPERATING EXPENSES.  Operating expenses in fiscal 1995 increased $26.2
million, or 93.7%, to $54.1 million from $27.9 million in fiscal 1994. Operating
expenses as a percentage of sales increased to 40.4% in fiscal 1995 from 37.3%
in fiscal 1994, reflecting increased fixed expenses, higher spending levels and
goodwill amortization associated with the acquired Wireless and Telecom
business. Spending for research and development activities increased from $5.4
million in fiscal 1994 to $12.1 million in fiscal 1995.
    
 
    NON-OPERATING INCOME (EXPENSE).  Non-operating expense, net, in fiscal 1995
increased to $3.2 million from $1.0 million in fiscal 1994. The Company's net
interest expense increased to $1.1 million during fiscal 1995 from $0.6 million
during fiscal 1994, reflecting increased borrowings to complete the October 1994
acquisition by the Company of its Wireless and Telecom businesses. Other
non-operating expenses increased to $2.1 million in fiscal 1995 from $0.4
million in fiscal 1994, due primarily to a loss of $1.8 million incurred in
fiscal 1995 related to the sale and leaseback financing of the Company's
Indianapolis facility.
 
    PROVISION FOR INCOME TAXES.  The Company's effective tax rate in fiscal 1995
was 16.7%, compared to a fiscal 1994 effective rate of 18.1%.
 
    NET INCOME.  As a result of the above factors, net income was $3.1 million
in fiscal 1995 as compared to $3.7 million in fiscal 1994.
 
    EBITDA.  EBITDA was $9.9 million in fiscal 1995 as compared to $7.1 million
in fiscal 1994. EBITDA as a percentage of sales decreased to 7.4% in fiscal 1995
from 9.5% in fiscal 1994.
 
   
    RATIO OF EARNINGS TO FIXED CHARGES.  As a result of the above factors, the
ratio of earnings to fixed charges was 2.8x for fiscal 1995 as compared to 5.3x
for fiscal 1994.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The Company's cash flow from operating activities was $6.4 million, $12.5
million and $15.1 million in fiscal 1994, 1995 and 1996, respectively, and $14.1
million (excluding a one-time charge of $7.1 million for stock option
compensation related to the Recapitalization Transactions) for the nine months
ended June 30, 1997. The Company had cash, cash equivalents and short-term
investments at June 30, 1997 of $7.1 million. The Company invests its excess
cash in money market funds and U.S. Treasury obligations. Historically the
Company has funded its business through operating cash flow, has not relied on
sales of equity to provide cash and has used short-term debt primarily for cash
management purposes. The Company's European subsidiaries had borrowings
outstanding under their existing credit agreements (the "Existing Credit
Agreements") of $3.4 million at June 30, 1997 for funding short-term working
capital requirements, and the Company had additional obligations outstanding
totalling approximately $2.1 million in the form of letters of credit and bank
guarantees. As of June 30, 1997, the Company had outstanding an unsecured note
of approximately $0.9 million issued in the October 1994 acquisition of the
Company's Telecom business and a financing obligation of $4.1 million recorded
in connection with the
 
                                       41
<PAGE>
sale and leaseback of the Company's facilities in Indianapolis, Indiana. See
"Description of Other Indebtedness -- Other Debt."
 
   
    The Company's primary cash needs have been for the funding of working
capital requirements (primarily inventory) and capital expenditures. The
Company's net cash provided by (used in) investing activities was $0.1 million,
$(20.4 million) and $(4.0 million) in fiscal 1994, 1995 and 1996, respectively,
and $(7.6 million) for the nine months ended June 30, 1997. The Company's fiscal
1994 cash flows from investing activities include $0.9 million received as
proceeds from the sale of a business and the fiscal 1995 cash flows from
investing activities reflect $17.7 million paid in cash for the acquisition of
the Company's Wireless and Telecom Business. For the nine months ended June 30,
1997, the cash used in investing activities includes $3.0 million used to
purchase short-term investments. The Company's recurring cash requirements for
investing activities are for capital expenditures. The Company made capital
expenditures in fiscal 1994, 1995 and 1996 of $1.3 million, $2.9 million and
$4.5 million, respectively, and $4.8 million for the nine months ended June 30,
1997. Capital expenditures in fiscal 1994 and 1995 primarily reflect spending
for manufacturing and engineering equipment resulting from the increase in the
size of the business and the number of facilities following the October 1994
acquisition by the Company of its Wireless and Telecom businesses. In fiscal
1996, the expenditures reflect increasing investment in manufacturing and
engineering equipment and also include approximately $1.1 million related to
investing in new management information system hardware and software. The
Company expects its capital expenditures to increase to approximately $6.0
million in fiscal 1997, which would represent a higher than average percentage
of sales as compared to historical levels. These higher than average
expenditures primarily reflect the Company's continued investment in new
management information systems and manufacturing equipment.
    
 
   
    The Company's net cash provided by (used in) financing activities was $(6.4
million), $7.7 million and $(8.6 million) in fiscal 1994, 1995 and 1996,
respectively, and $(1.4 million) for the nine months ended June 30, 1997. In
fiscal 1994, these cash flows reflect the impact of a $7.0 million return of
capital to stockholders and in fiscal 1995, to raise cash for its acquisition of
the Wireless and Telecom business, the Company generated cash by issuing common
shares for $7.6 million and by entering into a sale and leaseback financing
transaction for $4.3 million. The Company also repurchased common shares in
fiscal 1995 for $3.2 million. The remaining cash flows from financing activities
in fiscal 1994, 1995 and 1996 reflect the proceeds from and repayments for
borrowings used to finance the Company's operating and investing activities, or
as an application of the cash generated from these activities. For the nine
months ended June 30, 1997, the net cash used in financing activities
substantially reflects the net impact of the Recapitalization Transactions.
    
 
    As part of the Recapitalization Transactions, the Company entered into the
New Credit Agreement with Fleet National Bank, DLJ Capital Funding, Inc. and
various other lenders providing for a term loan facility of $25.0 million and a
revolving credit facility providing for borrowings up to $20.0 million, of which
the Company borrowed all $25.0 million of the term loan facility and none of the
revolving credit facility to complete the Recapitalization Transactions. See
"Description of Other Indebtedness -- New Credit Agreement." In connection with
entering into the New Credit Agreement, the Company terminated $4.0 million of
availability under its Existing Credit Agreements, leaving borrowing
availability of approximately $10.5 million at its Foreign Subsidiaries. The
Company believes that its cash flow from operations, combined with the remaining
available borrowings under the Existing and New Credit Agreements will be
sufficient to fund its debt service obligations, including its obligations under
the Notes, and working capital requirements, as well as implement its growth
strategy.
 
FOREIGN OPERATIONS
 
    As discussed above, a significant portion of the Company's sales and
expenses are denominated in currencies other than the United States dollar. In
order to maintain access to such foreign currencies, the Company's subsidiaries
in the United Kingdom, France and Germany have credit facilities providing for
 
                                       42
<PAGE>
borrowings in British pounds, French francs and Deutsche marks, respectively.
The revolving credit facility under the New Credit Agreement provides for up to
an aggregate of $7.5 million of borrowings in British pounds, French francs and
Deutsche marks. Adjustments made in translating the balance sheet accounts of
the Foreign Subsidiaries from their respective functional currencies at
appropriate exchange rates are included as a separate component of stockholders'
equity. In addition, the Company periodically uses forward exchange contracts to
hedge certain known foreign exchange exposures. Gains or losses from such
contracts are included in the Company's statements of income to offset gains and
losses from the underlying foreign currency transactions.
 
    The Indenture and the New Credit Agreement permit the Company and its
subsidiaries to make investments in, and intercompany loans to, the Foreign
Subsidiaries. Payments to the Company or its other subsidiaries by such Foreign
Subsidiaries, including the payment of dividends, redemption of capital stock or
repayment of such intercompany loans, may be restricted by the credit agreements
of the Foreign Subsidiaries. All intercompany loans from the Company to the
Foreign Subsidiaries are pledged to the lenders under the New Credit Agreement.
 
PERIODIC FLUCTUATIONS
 
   
    The Company's LTM sales occurred in the following percentages in each of the
last four quarters: 23% for the quarter ended September 30, 1996; 27% for the
quarter ended December 31, 1996; 26% for the quarter ended March 31, 1997; and
24% for the quarter ended June 30, 1997. A variety of factors may cause
period-to-period fluctuations in the operating results of the Company. Such
factors include, but are not limited to, product mix, European summer holidays
and other seasonal influences, competitive pricing pressures, materials costs,
currency fluctuations, revenues and expenses related to new products and
enhancements of existing products, as well as delays in customer purchases in
anticipation of the introduction of new products or product enhancements by the
Company or its competitors. The majority of the Company's revenues in each
quarter results from orders received in that quarter. As a result, the Company
establishes its production, inventory and operating expenditure levels based on
anticipated revenue levels. Thus, if sales do not occur when expected,
expenditures levels could be disproportionately high and operating results for
that quarter, and potentially future quarters, would be adversely affected.

                                    BUSINESS
 
GENERAL
 
   
    Wavetek is a leading global designer, manufacturer and distributor of a
broad range of electronic test instruments, with a primary focus on
application-specific instruments used for testing voice, video and data
communications equipment and networks. The Company also designs, manufacturers
and distributes precision instruments to calibrate and test electronic equipment
and provides repair, upgrade and calibration services for its products on a
worldwide basis. The Company was acquired in 1991 by an investment group led by
Gooding and consummated the Recapitalization Transactions in June 1997 with the
New Equity Investors. The Company has increased sales from $58.1 million in
fiscal 1992 to $151.0 million in fiscal 1996, EBITDA from $3.8 million in fiscal
1992 to $20.9 million in fiscal 1996 and net income from $2.9 million in fiscal
1992 to $13.5 million in fiscal 1996 by increasing its penetration of existing
markets and by entering additional markets through introductions of new products
and acquisitions. For the LTM ended June 30, 1997, Wavetek had sales and EBITDA
of $154.5 million and $22.3 million, respectively. Wavetek's LTM net income was
$5.5 million after giving effect to a one-time charge of $4.3 million, net of
tax, for stock option compensation related to the Recapitalization Transactions.
    
 
    Wavetek believes it has achieved its success by: (i) focusing on the $2.5
billion Communications Test market segment of the test instrument industry,
which is expected to grow by approximately 10% per annum through 2001; (ii)
identifying changing industry trends and customer needs and successfully
introducing responsive new products on a timely basis; (iii) serving the
increasing demand for application-specific, portable field service and
maintenance equipment, which accounted for over 70% of the Company's LTM sales;
and (iv) leveraging its operations and development capabilities outside the
United States, where the Company generated 61% of its LTM sales. Wavetek
believes that its product development capabilities, product quality, breadth of
product line and geographic diversity should enable it to continue to expand its
share of existing markets and successfully enter new markets.
 
    The Company's Communications Test products, which accounted for 75% of the
Company's LTM sales, serve the CATV, Wireless, Telecom, LAN and Test Tools
segments of the test instrument industry. The primary end users for the
Company's Communications Test products are service, installation and maintenance
personnel of CATV operators, wireless communications companies,
telecommunications companies and data communications equipment installers. The
Company's CATV products are used by CATV operators to diagnose and monitor CATV
systems, test cable for signal quality and leakage and ensure the proper
installation of new services such as cable modems. The Company's Wireless
products are used by wireless operators, equipment manufacturers and retailers
to test mobile phones during production, repair, or at the point-of-sale and by
wireless operators to test base stations. The Company's Telecom products are
used by telecommunications companies to install and maintain fiber optic cable.
The Company's LAN products are used by LAN installation and service
professionals to test LAN cables and connectors ("physical layer"). The
Company's Test Tools products, primarily hand-held DMMs, are used to test a wide
variety of electronic and electrical equipment. The Company has strong
competitive positions in its target markets and believes it is the worldwide
market leader in the manufacture of CATV test equipment, the second largest
supplier of hand-held DMMs and one of the five largest manufacturers of Wireless
and physical layer LAN test equipment.
 
    The Company's Calibration Instruments products, which accounted for 17% of
the Company's LTM sales, are used in metrology, engineering and manufacturing
environments worldwide to calibrate electronic equipment and certify compliance
with international standards. The Company believes it is the second largest
global manufacturer of Calibration Sources and Transfer Standards. The Company's
Calibration Instruments products also include Precision DMMs. The Company
successfully competes in this market based on its technical expertise,
relationships with national laboratories and product reputation.
 
                                       44
<PAGE>
    The Company's Service business, which accounted for 8% of the Company's LTM
sales, provides repair, upgrade and calibration services for the Company's
products through eight Wavetek service centers worldwide and an international
network of independent representatives.
 
    Wavetek has global design, manufacturing, marketing and distribution
capabilities through facilities located in the United States, the United
Kingdom, France and Germany. The Company is committed to providing high quality
manufacturing and has received or is in the process of receiving ISO 9000
certification for each of its manufacturing facilities. In addition, Wavetek
supports its broad international base of over 5,000 customers with regional
sales offices in San Diego, Indianapolis, Norwich, Munich, Paris, Vienna,
Singapore, Hong Kong, Beijing and Shanghai. The Company's products are sold
through direct sales teams in the United States, the United Kingdom, France and
Germany and a global network of over 250 distributors and independent
representatives.
 
BUSINESS STRATEGY
 
    Wavetek believes that it has achieved its strong position in the
Communications Test and Calibration Instruments market segments by identifying
changing industry trends and customer needs, and by successfully introducing
high-quality, cost-effective, application-specific products to meet such needs
on a timely basis. The Company's business strategy is to further enhance its
strong position in these markets and to continue to increase sales and EBITDA
through the following key initiatives:
 
    - FOCUS ON THE LARGE, RAPIDLY GROWING COMMUNICATIONS TEST SEGMENT. The
      Company generated 75% of its LTM sales from Communications Test products
      and intends to continue to focus on this segment of the test instrument
      industry. Prime Data expects sales in the Communications Test
     market to grow at approximately 10% per annum from approximately $2.5
      billion in 1996 to approximately $4.0 billion in 2001. The Company
      believes that the drivers of this growth include (i) rapidly changing
      communications technology; (ii) growing demand for personal communications
      services (including mobile phones, interactive CATV and internet access);
      and (iii) increasing worldwide investment to build or upgrade data and
      communications infrastructure. Wavetek intends to capitalize on this
      large, rapidly growing market segment through its broad Communications
      Test product portfolio, extensive international presence and strong market
      positions in CATV, Wireless and LAN.
 
    - DEVELOP APPLICATION-SPECIFIC PRODUCTS FOR TARGET MARKETS ON A TIMELY
      BASIS. Wavetek's product development strategy is to: (i) focus on
      application-specific products that are responsive to customer needs; (ii)
      minimize development time in order to address rapidly changing technology;
      and (iii) leverage design efforts by generating multiple product line
      extensions from existing product platforms. Wavetek has a history of
      successful new product introductions, including eight new products in
      fiscal 1996, and the Company expects to introduce approximately ten new
      products in fiscal 1997.
 
    - MEET DEMAND FOR ENHANCED PORTABLE TEST INSTRUMENTS. The Company generated
      over 70% of its LTM sales from portable field service and maintenance
      equipment and intends to continue to focus on these types of products. The
      increasing complexity of communications technology is creating demand for
      field test equipment that incorporates enhanced measurement performance.
      Furthermore, service, installation and maintenance personnel are demanding
      smaller, more portable products that enable them to service systems and
      equipment in the field rather than at a service facility. As a result of
      its product design, manufacturing and distribution strengths in portable
      test instruments, the Company believes it will continue to benefit from
      these demand trends.
 
    - LEVERAGE INTERNATIONAL OPERATIONS AND DISTRIBUTION. The Company believes
      that international capital investment in communications infrastructure has
      provided and will continue to provide growth in the worldwide
      Communications Test market. Wavetek believes it is well-positioned to
      capitalize on this growth with its substantial international operations
      that include: (i) three foreign manufacturing facilities; (ii) established
      international sales and distribution channels; and (iii) approximately 450
      employees located outside of the United States. The Company generated 61%
      of its LTM sales
 
                                       45
<PAGE>
      from customers outside the United States and believes its international
      operations should enable it to gain market share in existing international
      markets and successfully enter new markets, particularly in the
      Asia-Pacific, Eastern Europe and South America regions. Additionally, the
      Company believes that its strategic alliance formed in 1996 with Yokogawa,
      a leading Japanese process control and test and measurement company,
      coupled with the development of new products tailored for the Japanese
      market, will increase the Company's sales in Japan.
 
    - ENHANCE PROFITABILITY THROUGH CONTINUED IMPROVEMENT IN THE WIRELESS AND
      TELECOM BUSINESSES. Wavetek has taken measures to improve the operations
      of its Wireless and Telecom businesses acquired in October 1994,
      including: (i) introducing new products with higher gross margins; (ii)
      rationalizing old, low margin businesses and products; (iii) reducing
      headcount; (iv) hiring new management; and (v) reducing marketing and
      selling expenses as a percentage of sales. As a result of these ongoing
      efforts, the Company has significantly improved the operating results of
      these acquired businesses. As new products with higher margins continue to
      replace older products, and as the Company makes additional cost
      improvements in its European manufacturing operations, the Company expects
      results from these businesses to continue to improve.
 
TEST INSTRUMENT INDUSTRY
 
    The global test instrument industry encompasses the manufacturing, marketing
and distribution of a wide variety of electronic test equipment used in the
design, development and service of various types of electronic equipment, cables
and systems. Test instruments are used primarily by service, installation,
maintenance, manufacturing and research and engineering professionals in a broad
range of industries, including communications, technology, aerospace, process
control and automotive. Selected products include signal meters, DMMs, sweep
generators, spectrum analyzers, function generators and network analyzers.
Wavetek focuses on two segments of the $7.8 billion test instrument industry:
Communications Test and Calibration Instruments.
 
    COMMUNICATIONS TEST
 
    The Communications Test segment is the largest and one of the fastest
growing segments of the test instrument industry. This segment consists of a
broad range of equipment used to install, diagnose, maintain and service
equipment for voice, video and data communications networks. According to Prime
Data, sales in the Communications Test segment have grown from approximately
$1.2 billion in 1989 to approximately $2.5 billion in 1996. Prime Data further
expects this segment to grow approximately 10% per annum to over $4.0 billion by
2001. In 1995, approximately 61% of Communications Test market revenues occurred
outside of the United States, with Asia and Europe representing 25% and 28% of
the market, respectively, and the rest of the world representing 8%. The
following graph presents the historical and projected size (as compiled by Prime
Data) of the Communications Test segment of the test instrument industry:

    The Company believes that the consistent growth of the Communications Test
segment has been driven and will continue to be driven, in large part, by the
following factors:
 
    RAPIDLY CHANGING TECHNOLOGY.  Many segments of the communications industry
are experiencing rapid change due to new and competing technologies. For
example, digital formats are replacing analog formats in many forms of
communication systems. In addition, the need to increase data capacity should
lead to higher bandwidths, new signalling formats and new transmission
technologies. Each change or upgrade in communications systems or infrastructure
requires substantial testing, which creates demand for new or upgraded test
instruments.
 
    SUBSTANTIAL CAPITAL INVESTMENT IN COMMUNICATIONS INFRASTRUCTURE.  Developed
countries, such as the United States, are investing substantial capital to
construct, rebuild, upgrade and maintain information and communications systems.
Although such expenditures have slowed in certain areas, operators generally
need to upgrade their systems in order to support the increased demand for new
services and methods of communication that require more technologically advanced
communications infrastructure. Less mature countries, including selected
Asia-Pacific, Eastern European and South American countries, are building
communications infrastructure to meet increasing demand for basic communications
services such as CATV, Wireless and Telecom. Demand for Communications Test
products has historically depended upon capital spending for such communications
infrastructure.
 
    INCREASED DEMAND FOR WIRELESS PRODUCTS.  According to industry sources, the
number of global cellular and personal communications system ("PCS") subscribers
is expected to grow from 123 million in 1996 to 334 million in 2001,
representing an average growth rate of approximately 22% per annum. In addition
to the growth in subscribers, wireless technologies are constantly evolving. The
Company believes that the combination of growth in cellular and PCS subscribers
and changing technology should increase the need for wireless Communications
Test products.
 
    SHIFT TO ENHANCED PORTABLE FIELD TEST EQUIPMENT.  The increasing complexity
of communications technology is creating demand for field test equipment that
incorporates enhanced measurement performance. Furthermore, service and
installation personnel are demanding smaller, more portable products that enable
them to service systems and equipment in the field rather than at a service
facility. As a result, there is a continuing need to develop more portable field
test equipment with enhanced features and technology.
 
    CALIBRATION INSTRUMENTS
 
    The Calibration Instruments segment of the test instrument industry is
comprised of instruments which measure voltage, current, power quality,
frequency, temperature, pressure and other key functional parameters of
electronic equipment. Calibration Instruments are typically used by engineering
and manufacturing professionals and national laboratories to ensure that the
accuracy of the calibration or verification of electronic test equipment can be
traced to national, international or military reference standards. The Company
focuses on the metrology area of Calibration Instruments with three types of
products: Calibration Sources, Transfer Standards and Precision DMMs.
Calibration Sources provide high accuracy voltages and currents for calibrating
and verifying the accuracy of voltage measuring equipment. Transfer Standards
transfer the accuracy of voltage measurements from national standards
laboratories to industry calibration laboratories. Precision DMMs measure
voltages and currents produced by electronic equipment to accuracies up to 8 1/2
digits.
 
    The Company estimates that the aggregate market for these products was $365
million in 1996, with DMMs (of which Precision DMMs are a small segment),
Calibration Sources and Transfer Standards representing approximately 78%, 19%
and 3%, respectively, of the market. The Company believes that future growth in
the Calibration Instruments industry will be primarily driven by: (i) increased
adherence to quality standards such as ISO 9000, which require companies to
regularly calibrate and verify electronic
 
                                       47
<PAGE>
equipment used in manufacturing and repair; (ii) demand for more automated and
user-friendly Calibration Instruments to increase efficiency and allow less
skilled technicians to administer calibration procedures; and (iii) demand for
Calibration Instruments to accommodate a wider range of equipment with specific
test programs in order to increase efficiency and reduce the cost of calibration
and maintenance.
 
    The Company believes that several barriers to entry exist in the Calibration
Instruments market that limit the number of competitors. Users of Calibration
Instruments depend on the accuracy of such instruments and generally require
instrument manufacturers to have long standing reputations for technical
expertise and product quality. Furthermore, sales often depend on relationships
with major quality standards organizations such as national laboratories and
worldwide first tier metrology labs.
 
BUSINESS
 
    Within the test instrument industry, Wavetek has a primary focus on
Communications Test instruments. The Company also manufactures Calibration
Instruments and provides repair, upgrade and calibration services for its
products on a worldwide basis. The Company's Communications Test, Calibration
Instruments and Service businesses accounted for 75%, 17% and 8%, respectively,
of the Company's LTM sales.
 
    COMMUNICATIONS TEST
 
    The Company's Communications Test business, which accounted for 75% of the
Company's LTM sales, consists of CATV, Wireless, Telecom, LAN and Test Tools.
 
    CATV.  The Company is the global leader in developing and manufacturing test
equipment used for commissioning new and maintaining existing CATV networks.
Major products include: sweep systems, signal level meters, leakage meters,
monitoring systems and related software. These products allow CATV operators to
test and monitor the quality of signals transmitted over a CATV network. The
Company believes that the development and deployment by CATV operators of
advanced services, including two-way data paths to provide telephony or internet
services, has created new product opportunities for Wavetek. For example,
Wavetek's close customer relationships gave the Company early indication of the
need for return path testing capability. Wavetek used this information to create
an extension to Wavetek's successful Stealth product line to assist CATV
technicians in the installation and servicing of the return path of CATV
networks.
 
    One of the primary technical problems facing two-way CATV networks is
interference (noise) on the return path. If the return path is not securely
installed with tight connectors and well-maintained cable, noise from external
sources such as computers, home appliances and motors can enter the CATV system,
be amplified and interfere with data on the return path. In order to reduce the
time and difficulty in locating the source of noise, Wavetek has developed a
family of leakage meters, including the CLI 1750, that assists installers in
detecting leaks in CATV networks.
 
    Significant CATV customers of the Company include Continental Cablevision,
Inc., Deutsche Telekom A.G., TCI and Time Warner Cable. The Company's CATV
business is headquartered in Indianapolis, Indiana.

    WIRELESS.  The Company's Wireless business, acquired from Schlumberger in
October 1994, is one of the world's five largest manufacturers of test
instruments for mobile phone and base station testing and service. Wavetek
manufactures instruments to test most analog and digital formats including PCS,
Groupe Speciale Mobile ("GSM"), Time Division Multiple Access ("TDMA") and Code
Division Multiple Access ("CDMA"). The Company's products are used during the
manufacturing process, at service facilities and at the point-of-sale. Wavetek's
point-of-sale application-specific product for the Wireless market, the 4100 GSM
Tester, was designed to address the increasing demand for testing in the GSM
market. The shift in phone repair from local repair shops or retail stores to
high volume service facilities, combined with the high cost to process, ship and
test a phone at a service facility, is creating a need for "go/no-go" testing at
retail sites to minimize the number of properly functioning phones that are
mistakenly returned to the manufacturer for repair. The 4100 GSM Tester family
provides accurate "go/no-go" testing at a price point approximately one-third of
the price of traditional service testers, allowing economical sorting of phones
at the point-of-sale. Wavetek was able to bring the 4100 GSM Tester family to
market quickly, due in part to the application of technology from its LAN
products and existing wireless products.
 
    Wavetek's 3600D CDMA Tester provides application-specific, low cost service
capability on cellular or PCS phones that use CDMA technology. In the early
phase of the deployment of a new phone technology, phones must be thoroughly
tested prior to delivery to customers, as well as during repair. This testing
can be performed with manufacturing-oriented test instruments ranging in price
from $50,000-$60,000. However, as new phones are shipped in higher volumes, a
more economical, easier to use tester is desired. The 3600D CDMA Tester is a
lower cost (approximately $28,000) solution for phone commissioning and repair.
 
    Significant Wireless customers of the Company include AT&T and Ericsson. The
Company's Wireless business is headquartered in Munich, Germany, with
engineering and marketing teams in Indianapolis, Indiana.

    TELECOM.  The Company's Telecom business, also acquired from Schlumberger in
October 1994, designs and manufactures test instruments, systems and software
used for the installation, maintenance and monitoring of fiber optic cable. The
Company serves this market with both mainframe and portable optical time domain
reflectometers ("OTDRs"), remote fiber test systems ("RFTS"), light sources,
optical power meters and various other products. As Telecom operators install
more passive optical networks ("PONs") and provide fiber to the home ("FTTH"),
demand has increased for more versatile OTDRs. Wavetek's new MTS-5000 OTDR
family responds to this trend by offering a modular product that allows
installers to have specialized high resolution modules for PONs and FTTH
networks, in addition to high performance modules for long distance links. With
this family of products Wavetek combined the high performance optical knowledge
of its OTDR design team with the low cost design expertise of its CATV
engineering group, resulting in a product that offers high performance features
at a competitive cost. Wavetek intends to add multi-mode modules used for LAN
fiber measurements to its OTDR family during 1998.
    
 
    Significant Telecom customers of the Company include France Telecom, Russia

    LAN.  The Company acquired its LAN business as part of the Beckman
acquisition in October 1992, and the Company is now one of the five largest
global manufacturers of physical layer LAN test equipment. LAN testing products
include diagnostic instruments used to certify and verify the integrity of the
LAN physical layer. The Company's products are used by third party cable
installers, value added resellers of network equipment and management
information systems managers to verify the quality of cable installation. The
Company has developed its LT-8000 family of LAN cable testers to measure the
next generation of LAN cable rated to 650 MHz bandwidth, compared to the current
100 MHz standard. The Company was able to design the LT-8000, a cost effective,
high performance unit, by combining its expertise in high speed oscilloscope
calibration from its Calibration Instruments business with expertise in RF
technology from its CATV business.
 
    Significant LAN customers of the Company include distributors such as
Anixter International, Inc. and Graybar Electric Company, Inc. The Company's LAN
business is headquartered in San Diego, California.

one customer accounted for more than 5% of the Company's sales and the top ten
customers represented approximately 17% of sales.
 
PRODUCT DEVELOPMENT
 
    The Company seeks to develop and introduce application-specific products for
its target markets on a timely basis. The Company designs products for domestic
and international markets and often deploys market research and product
definition teams worldwide to meet and work with major communications and
metrology customers in order to determine and address the needs of its
customers.
 
    Wavetek's product development strategy is to: (i) focus on
application-specific products that are responsive to market-driven customer
needs; (ii) minimize development time in order to be responsive to shifts in
market demand and meet customer needs on a timely basis; (iii) aggressively
drive cost reductions throughout the design process; and (iv) leverage design
efforts by generating product families and product line extensions from existing
product platforms.
 
    As of March 31, 1997, the Company had approximately 130 employees involved
in its engineering activities who operate in teams based out of five locations
and generally focus on product development within a particular business area. In
addition, Wavetek's engineering teams share or apply other teams' product
designs where possible to improve use of resources. The Company typically
introduces 8 to 12 major new products or product extensions per year and expects
to introduce approximately 10 new products in fiscal 1997.
 
    The Company intends to continue to develop products to meet market demands
for reduced cost, size and weight, while achieving increased performance through
the use of application-specific integrated circuits ("ASICs"), digital signal
processing ("DSP") technology and increasing computing power available in
embedded processors. The Company has made a significant effort in recent years
to supplement its engineering staff with engineers skilled in these key
technology areas, as well as emerging technology areas such as digital
communications and advanced signal processing. The Company also makes selective
use of outside technical consulting companies to supplement internal
capabilities.
 
SALES AND DISTRIBUTION
 
   
    Wavetek products are sold through direct sales teams in the United States,
the United Kingdom, France and Germany. The Company also utilizes a network of
over 250 distributors and independent representatives. Wavetek sales personnel
manage and provide technical support to the distributors and independent
representatives. The Company's contracts with such distributors and independent
representatives are generally short-term in nature and generally can be
terminated by either party with 30 to 90 days notice. Sales offices are located
in the United States, the United Kingdom, France, Germany, Austria, Singapore,
Hong Kong, Beijing and Shanghai. As of March 31, 1997, Wavetek had approximately
130 employees involved in sales and customer support activities. The Company
also markets its products through advertising and participating in trade shows.
    
 
YOKOGAWA RELATIONSHIP
 
    In April 1996, Wavetek formed a strategic alliance with Yokogawa to jointly
develop Communications Test products for the Japanese market and to distribute
Wavetek's products in Japan. In September 1996, Yokogawa also purchased
approximately 12.0% of the Company's Common Stock outstanding prior to the
Recapitalization Transactions. As of the date of this Prospectus, Yokogawa owns
approximately 5.8% of the outstanding Common Stock of Wavetek. See "Ownership of
Capital Stock."
 
    Yokogawa, based in Tokyo, Japan, is a leading supplier of process control
equipment and test and measurement equipment. It currently distributes Wavetek's
CATV, Wireless, LAN and Calibration Instruments product lines in Japan. In
fiscal 1996, Wavetek's sales through Yokogawa were approximately $1.8
 
                                       54
<PAGE>
million. In addition, Wavetek and Yokogawa have joint engineering and marketing
programs for Wireless products. With the support of Yokogawa engineers located
in Wavetek's Indianapolis and Munich facilities, Wavetek and Yokogawa are
developing products aimed at the Japanese cellular market. The first product is
a cellular tester for the Japanese CDMA market based on Wavetek's 3600D CDMA
Tester product line, which is expected to be introduced in late fiscal 1997.
 
BACKLOG
 
    As of June 30, 1997, the Company had a firm open order backlog of $22.3
million (compared to $32.4 million as of June 30, 1996), of which it expects
less than $1.0 million may not be shippable prior to September 30, 1997. Backlog
reflects firm customer orders for products and services scheduled for shipment
within 12 months. The level of backlog at any particular time is not necessarily
indicative of future operating performance of the Company. Delivery schedules
may be extended, and orders may be canceled at any time subject to certain
cancellation penalties.
 
MANUFACTURING
 
    Wavetek has four manufacturing facilities worldwide. All North American
designed products except Test Tools (CATV, LAN and US-designed Wireless
products) are manufactured in Indianapolis. The Company manufactures its
Calibration Instruments products in Norwich, England, its Telecom products in
St. Etienne, France and its German-designed Wireless products in Munich,
Germany. Since the Company outsources certain of its manufacturing to
subcontractors, including the printed circuit boards for its French and German
products, the manufacturing at its St. Etienne and Munich facilities consists
primarily of final assembly and test. These facilities were acquired in the
October 1994 Schlumberger acquisition, and the Company is currently evaluating
consolidation opportunities in order to improve manufacturing efficiency and
capitalize on economies of scale. The Company's Test Tools products are
manufactured by third party suppliers, primarily in Taiwan.
 
    Although the Company attempts to use common, multi-sourced components
throughout its design, certain technological requirements may necessitate the
use of single-sourced, unique components. The Company attempts to minimize its
exposure on these components through careful vendor qualification and
purchasing, though risk exists that these parts may become obsolete,
necessitating redesign or withdrawal of the product from the market.

COMPETITION
 
    The Company operates in markets that are highly competitive, and the Company
expects that competition will increase in the future. Some of the industries in
which the Company operates are characterized by rapid technological advances and
emerging industry standards. Failure to keep pace with technological advances
would adversely affect the Company's competitive positions and results of
operations. The Company competes primarily on the basis of technology,
performance, price, brand identity, quality, reliability, distribution and
customer service and support. To remain competitive, the Company must continue
to develop new products, periodically enhance its existing products and compete
effectively in the areas described above. Although the Company believes its
products are competitive in each of these areas, there can be no assurance that
existing or future competitors, some of which have greater financial resources
than the Company, will not introduce comparable or superior products
incorporating more advanced technology at lower prices.
 
    The Company's competitors are numerous, ranging from some of the world's
largest corporations to many relatively small and highly specialized firms.
Although no single company competes in all of the Company's product markets,
some of the major competitors which compete in the individual product markets
include Anritsu Corporation, Fluke Corporation, Hewlett-Packard Company,
Microtest, Inc., Rohde & Schwartz, Inc. and Tektronix, Inc. Some of these
competitors have more extensive engineering, manufacturing and marketing
capabilities and substantially greater financial, technological and personnel
resources than the Company.
 
INTELLECTUAL PROPERTY
 
    The Company's success and ability to compete depends in part upon protecting
its proprietary technology. The Company relies upon a combination of patents,
trademark and trade secret laws, together with licenses, confidentiality
agreements and other contractual covenants, to establish and protect its
technology and other intellectual property rights.
 
                                       56
<PAGE>
    There can be no assurance that the steps taken by the Company to protect its
proprietary rights will be adequate to deter misappropriation or independent
third-party development of its technology, or that its intellectual property can
be successfully enforced or defended if challenged. Given the rapid development
of technology, there can be no assurance that certain aspects of the Company's
products do not or will not infringe upon the existing or future proprietary
rights of others or that, if licenses or rights are required to avoid
infringement, such licenses or rights could be obtained or obtained on terms
that would not have a material adverse effect on the Company. In any event,
because of the rapid pace of technological change in many of the Company's
product industries, the Company believes that patent protection for its products
is less significant to its success than the knowledge, ability and experience of
its employees and the frequent introduction and market acceptance of new
products and product enhancements. The Company uses a number of trademarks in
its business, including Wavetek-Registered Trademark-,
LANTEK-Registered Trademark- and Stabilock which are registered in various
countries where the Company operates. The Company currently has fourteen patents
and two pending patent applications and expects to rely on patents to a greater
extent in the future.
 
EMPLOYEES
 
    As of June 30, 1997, the Company had approximately 800 employees. Many of
the Company's employees are highly skilled and the Company's continued success
will depend in part upon its ability to attract and retain these employees. Many
of the Company's manufacturing employees in Europe are members of standard
unions. The Company believes its relationship with its employees is good.
 
LEGAL PROCEEDINGS
 
    In the ordinary course of its business, the Company from time to time is
subjected to legal claims. The Company does not believe that the likely outcome
of any such claims or related lawsuits would have a material adverse effect on
the Company or its ability to develop new products.
 
    A matter is pending in the United States District Court for the Western
District of Washington involving a claim that certain models of the Company's
hand-held DMMs infringe the trade dress of certain Fluke Corporation ("Fluke")
competitive products in violation of Section 43(a) of the Lanham Act, 15 U.S.C.
Section1125(a) and state statutory and common law, seeking injunctive and
monetary relief of approximately $1 million. Wavetek no longer sells hand-held
DMMs with the trade dress that Fluke alleged infringed its trade dress, and
Wavetek sold such DMMs for a period of less than ten months. The Company and
Fluke have entered into a settlement agreement resolving all of Fluke's claims,
but the action has not yet been dismissed with prejudice due to the inability of
the parties to agree upon the language of a Consent Judgment, which is to be
entered pursuant to the settlement. Under the terms of the settlement, Wavetek
has no financial obligations. However, if the settlement is not finalized, it is
possible that Fluke will be permitted to reassert its claims. The Company does
not believe that the litigation, even if the present settlement is not
finalized, is likely to have a material adverse impact on the Company.
 
    A matter is pending in the United States District Court for the Southern
District of Indiana, involving a claim by Trilithic, Inc. ("Trilithic") that
certain products of the Company infringe Trilithic's patent on a radio frequency
leakage detection system for a CATV system and seeks injunctive and unspecified
monetary relief. The product line potentially affected by this claim, and by a
second patent that has been issued to Trilithic subsequent to the filing of the
lawsuit, had LTM sales of approximately $5.8 million. Trilithic's complaint,
which was served on the Company in March 1997, was the first notice to the
Company of Trilithic's patent. The Company is presently obtaining advice of
counsel as to the claim of infringement and as to the validity and
enforceability of the patent. In the event the outcome of such investigation is
not favorable, the Company could be required to: (i) redesign existing or future
products so that they do not use the rights covered by Trilithic's patent; (ii)
negotiate licenses from Trilithic; or (iii) withdraw existing products or not
introduce future products that are covered by those patent rights. The Company
could also be liable to Trilithic for damages for any infringement since March
1997. The Company does not believe that any such damages are likely to have a
material adverse impact on the Company.
 
                                       57
<PAGE>
   
    In addition, the Company has been notified by two other competitors that
they believe that certain of the Company's CATV product lines, including in one
case its Stealth line of products, infringe their patents. The Company has
investigated or is currently investigating the validity of these two claims and,
based upon its investigation to date, believes that both of these claims can be
resolved in a manner that will not have a material adverse impact on the
Company. However, there can be no assurance that either or both of these
competitors will not initiate litigation against the Company and may not prevail
in such litigation. To the extent that the Company does not prevail in any such
litigation or either or both of these claims are proven, the Company could be
required to: (i) redesign existing or future products so that they do not use
the rights covered by the patent rights in question; (ii) negotiate licenses or
other rights to use those patent rights; (iii) withdraw existing products or not
introduce future products that are covered by those patent rights; or (iv) pay
damages for any past infringement, any and all of which could have a material
adverse impact on the Company. See "Risk Factors--Dependence on Proprietary
Rights."

BOARD OF DIRECTORS
 
    Members of the Board of Directors serve until the next annual meeting of
Stockholders and until a successor has been elected and qualified. Pursuant to
the Stockholders Agreement, the members are designated as follows: (i) two (or
three if an additional director is designated as described in this paragraph) of
such members shall be persons designated by DLJMB for as long as DLJMB and/or
their Permitted Transferees own at least 20% of the outstanding Common Stock of
the Company; (ii) one of such members shall be a person designated by GEI for so
long as GEI and/or its Permitted Transferees shall own at least 5% of the
outstanding Common Stock of the Company; (iii) three (or four if an additional
director is designated as described in this paragraph) of such members will be
persons designated by Gooding for as long as Gooding and/or his Permitted
Transferees own at least 10% of the
 
                                       60
<PAGE>
outstanding Common Stock of the Company; and (iv) one of such members shall be a
person designated by Gooding for as long as Gooding and/or his Permitted
Transferees own at least 10% of the outstanding Common Stock of the Company,
subject to approval by DLJMB for as long as DLJMB and/or their Permitted
Transferees own at least 20% of the outstanding Common Stock of the Company. In
the event DLJMB and/or their Permitted Transferees own at least 10% but less
than 20% of the outstanding Common Stock of the Company, DLJMB shall have the
right to appoint only two directors. In the event DLJMB and/or their Permitted
Transferees own at least 5% but less than 10% of the outstanding Common Stock of
the Company, DLJMB shall have the right to appoint only one director. In the
event Gooding and/or his Permitted Transferees own at least 5% but less than 10%

appoint only two directors. Prior to a Qualified IPO (as defined in the
Stockholders Agreement), each of DLJMB and Gooding may designate an additional
director. There are currently seven directors of the Company, each of whom is
named under "--Executive Officers and Directors."
 
    The Company's Certificate of Incorporation contains a provision permitted
under the Delaware General Corporation Law (the "DGCL") eliminating each
director's personal liability for monetary damages for breach of fiduciary duty
as a director, except to the extent that such exemption from liability or
limitation thereof is not permitted under the DGCL as currently in effect at the
time. The Company's Bylaws authorize the Company to indemnify its present and
former directors, officers and employees against expenses, judgments, fines and
amounts paid in settlement if such person is made a party, or is threatened to
be made a party, to a legal proceeding by reason of the fact that such person is
or was a director, officer, employee or agent of the Company, or was serving in
such position at another company at the request of Wavetek. Such indemnification
is mandatory in certain circumstances and permissive in others, subject to
authorization by the Company's Board of Directors. In addition, the Bylaws
authorize the Company to advance litigation expenses to such person prior to the
final disposition of the legal proceeding.
 
BOARD COMMITTEES
 
    The Board of Directors has three standing committees: an Executive
Committee, an Audit Committee and a Compensation Committee (together, the
"Committees"). The Executive Committee, currently consisting of Messrs. Bates,
Gooding, Moelis, Morikawa and Nolan, has the power to exercise all of the powers
and authority of the Board of Directors in the management of the business of the
Company, with certain exceptions. The Audit Committee, currently consisting of
Messrs. Baker, Nolan and Wilson, meets with the Company's financial management
and its independent accountants at various times during each year, reviews
internal control conditions, audit plans and results, and makes recommendations
to the Board of Directors concerning the Company's engagement of independent
accountants. The Compensation Committee, currently consisting of Messrs. Bates,
Gooding, Nolan and Wilson, reviews and proposes to the Board of Directors
compensation arrangements for directors and officers of the Company.

EMPLOYMENT AGREEMENTS
 
    The Company does not currently have any employment agreements with any of
its directors or executive officers. In connection with the Recapitalization
Transactions, the Company entered into executive severance agreements with each
of the Named Executive Officers providing for a specified level of U.S. benefits
and for a lump sum payment upon termination other than for cause equal to twenty
four months salary if termination occurs in the first month following June 11,
1997, the date on which the Recapitalization Transactions were consummated,
declining by one month for each month thereafter until the twelfth month
following June 11, 1997, after which the lump sum payment will equal twelve
months salary.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Board of Directors established a Compensation Committee in July 1997.
Messrs. Bates, Gooding, Nolan and Wilson are the members of the Compensation
Committee. Other than Mr. Gooding, none of the members of the Compensation
Committee has served as an officer or employee of the Company. Prior to the
establishment of the Compensation Committee, all decisions relating to
compensation of executive officers were made by the Company's Board of
Directors. For a description of the transactions between the Company and members
of the Compensation Committee and entities affiliated with such members, see
"Certain Relationships and Related Transactions." No executive officer of the
Company serves as a member of the board of directors or compensation committee
of any entity which has one or more executive officers serving as a member of
the Company's Board of Directors or Compensation Committee.
 
COMPENSATION OF DIRECTORS
 
    Executive officers of the Company and representatives of the New Equity
Investors who serve on the Board of Directors do not receive any compensation
for such services. Other directors receive $10,000 per year, plus a fee of
$2,500 per Board meeting attended and are reimbursed for their expenses incurred
in connection with attendance of meetings of, and other activities relating to
serving on, the Board of Directors. Members of the Committees of the Board of
Directors receive no additional compensation for their membership in, or
participation in the meetings of, such Committees.

STOCK OPTION PLAN
 
    From time to time, the Company issues stock options to employees of the
Company in order to attract, retain and provide equity incentives to key
employees and to stimulate the efforts of such employees. One quarter of each
grant of stock options becomes exercisable on each anniversary date of their
issuance, so that after four years, all of the options are vested.
 
    Pursuant to the Recapitalization Transactions, 75% of the stock options
existing prior to the Recapitalization Transactions, representing 805,000
shares, were vested and the holders thereof had the right to surrender such
options to the Company for a cash payment equal to the difference between the
purchase price per share of the New Equity Investment and the exercise price of
the options, less a pro rata portion of certain fees payable to DLJ.
Approximately 59% of the stock options existing prior to the Recapitalization
Transactions were surrendered for a cash payment. The aggregate pre-tax cost to
the Company was approximately $7.1 million ($4.3 million net of a related income
tax benefit).

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
    During fiscal year 1994, the Company received loans from Gooding aggregating
$4.5 million. Such loans were fully repaid, with interest, on September 30,
1994.
 
    During fiscal year 1994, the Company received a loan from Schroder UK
Venture Fund III L.P. ("Schroder") in the amount of $360,000. Such loan was
fully repaid, with interest, on October 26, 1994.
 
    In September 1995, the Board of Directors of the Company resolved that in
the event Gooding's shareholdings in the Company are reduced to less than 50% of
the outstanding shares, and/or if Gooding's employment as Chief Executive
Officer of the Company is terminated for any reason, Gooding or his nominee
shall have the right, but not the obligation, to take over the lease and
occupancy of the Company's executive offices at 11995 El Camino Real, Suite 301,
San Diego, California 92130, and to purchase all of the leasehold improvements
and fixed assets (including furniture, fixtures, paintings and office equipment)
located in such offices at such time, at depreciated net book value. See
"Business -- Properties and Facilities."
 
    The Company leases its headquarters for its LAN and Test Tools businesses in
San Diego from a corporation controlled by Gooding for an annual rent of
$585,000, plus annual consumer price index adjustments, not to exceed 3% per
annum. The lease expires in June 2006. See "Business -- Properties and
Facilities."
 
    The Company and Gooding were parties to shareholders agreements with
Yokogawa and Schroder, which were terminated as part of the Recapitalization
Transactions. The Company, Gooding, Yokogawa and Schroder entered into the
Stockholders Agreement with the New Equity Investors, which contains provisions
relating to the election of directors. See "Management -- Board of Directors."
The Stockholders Agreement also provides for transfer restrictions on the shares
of Common Stock held by such stockholders, rights of first offer, tag-along
rights, preemptive rights and certain other matters relating to the ownership
and sales of Common Stock of the Company.
 
    The Company is a party to a distribution agreement with Yokogawa pursuant to
which Yokogawa has the right to distribute the Company's products in Japan and a
technical collaboration agreement pursuant to which Wavetek and Yokogawa develop
joint engineering and marketing programs for Wireless products, both of which
were entered into in connection with the purchase by Yokogawa of Common Stock of
the Company in April 1996. See "Business -- Yokogawa Relationship."

                              DESCRIPTION OF NOTES
 
GENERAL
 
    The New Notes will be issued pursuant to the Indenture governing the Old
Notes between the Company and The Bank of New York, as Trustee. The terms of the
New Notes are identical in all material reports to the respective terms of the
Old Notes, except that the New Notes have been registered under the Securities
Act and therefore will not be subject to certain restrictions on transfer
applicable to the Old Notes and will not be entitled to registration rights. The
terms of the Notes include those stated in the Indenture and those made part of
the Indenture by reference to the Trust Indenture Act of 1939 (the "Trust
Indenture Act"). The Notes are subject to all such terms, and Holders of Notes
are referred to the Indenture and the Trust Indenture Act for a statement
thereof. The following summary of the material provisions of the Indenture does
not purport to be complete and is qualified in its entirety by reference to the
Indenture, including the definitions therein of certain terms used below. Copies
of the Indenture and Registration Rights Agreement are filed as exhibits to the
Registration Statement of which this Prospectus is a part. The definitions of
certain terms used in the following summary are set forth below under "--
Certain Definitions." For purposes of this summary, the term "Company" refers
only to Wavetek Corporation and not to any of its Subsidiaries.
 
    The Notes are subordinated in right of payment to all current and future
Senior Debt, including borrowings under the New Credit Agreement. The Subsidiary
Guarantees are subordinated in right of payment to all existing and future
Senior Debt of the Subsidiary Guarantors, including guarantees of the New Credit
Agreement. The Notes, the Subsidiary Guarantees and borrowings under the New
Credit Agreement are effectively subordinated to the indebtedness of the Foreign
Subsidiaries. As of June 30, 1997, the Company and its Subsidiary Guarantors had
approximately $25.0 million of Senior Debt and the Foreign Subsidiaries had
approximately $4.3 million of outstanding debt, all of which would effectively
rank senior to the Notes and the Subsidiary Guarantees. The Indenture permits
the Company and its Subsidiaries to incur additional indebtedness, including
Senior Debt, subject to certain limitations, and prohibits the incurrence of any
indebtedness that is senior to the Notes and subordinated to Senior Debt.
 
    The Notes are limited in aggregate principal amount to $85.0 million and
will mature on June 15, 2007. Interest on the Notes will accrue at the rate of
10 1/8% per annum and will be payable semi-annually on June 15 and December 15
of each year, commencing on December 15, 1997, to Holders of record on the
immediately preceding June 1 and December 1. Interest on the Notes will accrue
from the most recent date to which interest has been paid or, if no interest has
been paid, from the Issue Date. Interest will be computed on the basis of a
360-day year comprised of twelve 30-day months.
 
    Principal of and premium, interest and Liquidated Damages, if any, on the
Notes will be payable at the office or agency of the Company maintained for such
purpose within the City and State of New York or, at the option of the Company,
payment of interest and Liquidated Damages, if any, may be made by check mailed
to the Holders of the Notes at their respective addresses set forth in the
register of Holders of Notes; PROVIDED that all payments of principal, premium,
interest and Liquidated Damages, if any, with respect to Global Notes and with
respect to Certificated Notes the Holders of which have given wire transfer
instructions to the Company, will be required to be made by wire transfer of
immediately available funds to the accounts specified by the Holders thereof.
Until otherwise designated by the Company, the Company's office or agency in New
York will be the office of the Trustee maintained for such purpose. The Notes
will be issued in denominations of $1,000 and integral multiples thereof.
 
SUBSIDIARY GUARANTEES
 
   
    The Company's payment obligations under the Notes are jointly and severally
guaranteed (the "Subsidiary Guarantees") on a full and unconditional senior
subordinated basis by the Subsidiary Guarantors. As of the date of this
Prospectus, Wavetek U.S. Inc. is the only Subsidiary Guarantor. The Subsidiary
Guarantee of each Subsidiary Guarantor is subordinated to the prior payment in
full of all Senior Debt of
    
 
                                       67
<PAGE>
the Subsidiary Guarantors, which, as of June 30, 1997 includes approximately
$25.0 million of Indebtedness, which presently consists solely of the Guarantees
of the New Credit Agreement. The obligations of each Subsidiary Guarantor under
its Subsidiary Guarantee are limited so as not to constitute a fraudulent
conveyance under applicable law. See, however, "Risk Factors -- Fraudulent
Conveyance Matters."
 
    The Indenture provides that no Subsidiary Guarantor may consolidate with or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person), another corporation, Person or entity whether or not affiliated with
such Subsidiary Guarantor unless: (i) subject to the provisions of the following
paragraph, the Person formed by or surviving any such consolidation or merger
(if other than such Subsidiary Guarantor) assumes all the obligations of such
Subsidiary Guarantor, pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee, under the Subsidiary Guarantee and the
Indenture; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; and (iii) the Company would be permitted by virtue
of the Company's pro forma Fixed Charge Coverage Ratio, immediately after giving
effect to such transaction, to incur at least $1.00 of additional Indebtedness
pursuant to the Fixed Charge Coverage Ratio test set forth in the covenant
described above under the caption "-- Certain Covenants -- Incurrence of
Indebtedness and Issuance of Preferred Stock." The requirements of clause (iii)
of this paragraph will not apply in the case of a consolidation or merger of a
Subsidiary Guarantor with or into the Company or another Subsidiary Guarantor.
 
    The Indenture provides that in the event of a sale or other disposition of
all of the assets of any Subsidiary Guarantor, by way of merger, consolidation
or otherwise, or a sale or other disposition of all of the capital stock of any
Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or
other disposition, by way of such a merger, consolidation or otherwise, of all
of the capital stock of such Subsidiary Guarantor) or the corporation acquiring
the property (in the event of a sale or other disposition of all of the assets
of such Subsidiary Guarantor) will be released and relieved of any obligations
under its Subsidiary Guarantee; PROVIDED that the Net Proceeds of such sale or
other disposition are applied in accordance with the applicable provisions of
the Indenture. See "-- Certain Covenants Asset Sales."
 
SUBORDINATION
 
    The payment of principal of, premium, interest and Liquidated Damages, if
any, on the Notes are subordinated in right of payment, as set forth in the
Indenture, to the prior payment in full in cash of all Senior Debt, whether
outstanding on the date of the Indenture or thereafter incurred.
 
    Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities, the holders of Senior Debt will be entitled to receive
payment in full in cash of all Obligations due in respect of such Senior Debt
(including interest after the commencement of any such proceeding at the rate
specified in the applicable Senior Debt whether or not allowable as a claim in
any such proceeding) before the Holders of Notes will be entitled to receive any
payment with respect to the Notes, and until all Obligations with respect to
Senior Debt are paid in full, any distribution to which the Holders of Notes
would be entitled shall be made to the holders of Senior Debt (except that
Holders of Notes may receive Permitted Junior Securities and payments made from
the trust described under "-- Legal Defeasance and Covenant Defeasance").
 
    The Company also may not make any payment upon or in respect of the Notes
(except in Permitted Junior Securities or from the trust described under "Legal
Defeasance and Covenant Defeasance") if (i) a default in the payment of the
principal of, premium, if any, or interest on Designated Senior Debt occurs and
is continuing or (ii) any other default occurs and is continuing with respect to
Designated Senior Debt that permits holders of the Designated Senior Debt as to
which such default relates to accelerate its maturity and the Trustee receives a
notice of such default (a "Payment Blockage Notice") from the
 
                                       68
<PAGE>
Company or the holders of any Designated Senior Debt. Payments on the Notes may
and shall be resumed (a) in the case of a payment default, upon the date on
which such default is cured or waived and (b) in case of a nonpayment default,
the earlier of the date on which such nonpayment default is cured or waived or
179 days after the date on which the applicable Payment Blockage Notice is
received, unless a payment default on any Designated Senior Debt then exists. No
new period of payment blockage may be commenced unless and until 360 days have
elapsed since the delivery of the immediately prior Payment Blockage Notice. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice.
 
    The Indenture further requires that the Company promptly notify holders of
Senior Debt if payment of the Notes is accelerated because of an Event of
Default.
 
    As a result of the subordination provisions described above, in the event of
a liquidation or insolvency, Holders of Notes may recover less ratably than
creditors of the Company who are holders of Senior Debt. As of June 30, 1997,
the principal amount of Senior Debt outstanding was approximately $25.0 million.
The Indenture limits, subject to certain financial tests, the amount of
additional Indebtedness, including Senior Debt, that the Company and its
subsidiaries can incur. See "-- Certain Covenants -- Incurrence of Indebtedness
and Issuance of Preferred Stock."
 
OPTIONAL REDEMPTION
 
    Except as set forth below, the Notes will not be redeemable at the Company's
option prior to June 15, 2002. Thereafter, the Notes will be subject to
redemption at any time at the option of the Company, in whole or in part, upon
not less than 30 nor more than 60 days' notice, at the redemption prices
(expressed as percentages of principal amount) set forth below plus accrued and
unpaid interest and Liquidated Damages, if any, to the applicable redemption
date, if redeemed during the twelve-month period beginning on June 15 of the
years indicated below:

proceeds of one or more Public Equity Offerings; PROVIDED that at least 66 2/3%
of the aggregate principal amount of Notes originally issued remains outstanding
immediately after such redemption; and PROVIDED, FURTHER, that such redemption
shall occur within 60 days of the date of the closing of such Public Equity
Offering.
 
    If less than all of the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange, if any, on which the
Notes are listed, or, if the Notes are not so listed, on a pro rata basis, by
lot or by such method as the Trustee shall deem fair and appropriate; PROVIDED
that no Notes of $1,000 or less shall be redeemed in part. Notices of redemption
shall be mailed by first class mail at least 30 but not more than 60 days before
the redemption date to each Holder of Notes to be redeemed at its registered
address. Notices of redemption may not be conditional. If any Note is to be
redeemed in part only, the notice of redemption that relates to such Note shall
state the portion of the principal amount thereof to be redeemed. A new Note in
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Note. Notes called
for redemption become due on the
 
                                       69

date fixed for redemption. On and after the redemption date, interest ceases to
accrue on Notes or portions of them called for redemption.
 
CERTAIN COVENANTS
 
    CHANGE OF CONTROL
 
    Upon the occurrence of a Change of Control, each Holder of Notes will have
the right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple thereof) of such Holder's Notes pursuant to the offer
described below (the "Change of Control Offer") at an offer price in cash equal
to 101% of the aggregate principal amount thereof plus accrued and unpaid
interest and Liquidated Damages, if any, to the date of purchase (the "Change of
Control Payment"). Within ten days following any Change of Control, the Company
will mail a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and offering to repurchase Notes on the
date specified in such notice, which date shall be no earlier than 30 days and
no later than 60 days from the date such notice is mailed (the "Change of
Control Payment Date"), pursuant to the procedures required by the Indenture and
described in such notice. The Company will comply with the requirements of Rule
14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the repurchase of the Notes as a result of a Change of Control.
 
    On the Change of Control Payment Date, the Company will, to the extent
lawful, (1) accept for payment all Notes or portions thereof properly tendered
pursuant to the Change of Control Offer, (2) deposit with the Paying Agent an
amount equal to the Change of Control Payment in respect of all Notes or
portions thereof so tendered and (3) deliver or cause to be delivered to the
Trustee the Notes so accepted together with an Officers' Certificate stating the
aggregate principal amount of Notes or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to each Holder of Notes so tendered
the Change of Control Payment for such Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book entry) to each Holder
a new Note equal in principal amount to any unpurchased portion of the Notes
surrendered, if any; PROVIDED that each such new Note will be in a principal
amount of $1,000 or an integral multiple thereof. The Company will publicly
announce the results of the Change of Control Offer on or as soon as practicable
after the Change of Control Payment Date.
 
    The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the Notes to require that the Company
repurchase or redeem the Notes in the event of a takeover, recapitalization or
similar transaction.
 
   
    The New Credit Agreement currently prohibits the Company from purchasing any
Notes and also provides that certain change of control events with respect to
the Company would constitute a default thereunder. Any future credit agreements
or other agreements relating to Senior Debt to which the Company becomes a party
may contain similar restrictions and provisions. In the event a Change of
Control occurs at a time when the Company is prohibited from purchasing Notes,
then prior to purchasing the Notes in a Change of Control Offer, the Company
shall either repay all outstanding Senior Debt that contain such prohibitions or
obtain the requisite consents, if any, under all agreements governing such
outstanding Senior Debt. If the Company does not obtain such a consent or repay
such borrowings, the Company will remain prohibited from purchasing Notes. In
addition, it is possible that the Company will not have sufficient funds to make
the payments due upon a Change of Control. In either such case, the Company's
failure to purchase tendered Notes would constitute an Event of Default under
the Indenture which would, in turn, constitute as default under the New Credit
Agreement. In such circumstances, the subordination provisions in the Indenture
would likely restrict payments to the Holders of Notes. See "Risk Factors --
Possible Inability to Purchase Notes Upon a Change of Control."
    
 
                                       70
<PAGE>
    The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company,
including any requirement to repay in full any Senior Debt or obtain the
consents of such lenders to such Change of Control Offer as set forth in the
preceding paragraph, and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer.
 
    The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of Notes to require the Company to
repurchase such Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.
 
    ASSET SALES
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, consummate an Asset Sale unless (i) the Company (or the
Subsidiary, as the case may be) receives consideration at the time of such Asset
Sale at least equal to the fair market value (evidenced by a resolution of the
Board of Directors set forth in an Officers' Certificate delivered to the
Trustee) of the assets or Equity Interests issued or sold or otherwise disposed
of and (ii) at least 75% of the consideration therefor received by the Company
or such Subsidiary is in the form of cash; PROVIDED that the amount of (x) any
liabilities (as shown on the Company's or such Subsidiary's most recent balance
sheet), of the Company or any Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the Notes or any guarantee
thereof) that are assumed by the transferee of any such assets pursuant to a
customary novation agreement that releases the Company or such Subsidiary from
further liability and (y) any securities, notes or other obligations received by
the Company or any such Subsidiary from such transferee that are converted by
the Company or such Subsidiary into cash (to the extent of the cash received),
shall be deemed to be cash for purposes of this provision.
 
    Within 12 months after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (a) to repay permanently
Senior Debt or Senior Debt of the Subsidiary Guarantors, or (b) to the
acquisition of an interest in another business, the making of a capital
expenditure or the acquisition of other long-term assets, in each case, in the
test instrumentation industry or a business reasonably related thereto. Pending
the final application of any such Net Proceeds, the Company may temporarily
reduce revolving indebtedness under the New Credit Agreement or otherwise invest
such Net Proceeds in any manner that is not prohibited by the Indenture. Any Net
Proceeds from Asset Sales that are not applied or invested as provided in the
first sentence of this paragraph will be deemed to constitute "Excess Proceeds."
When the aggregate amount of Excess Proceeds exceeds $5.0 million, the Company
will be required to make an offer to all Holders of Notes (an "Asset Sale
Offer") to purchase the maximum principal amount of Notes that may be purchased
out of the Excess Proceeds, at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest and Liquidated
Damages, if any, to the date of purchase, in accordance with the procedures set
forth in the Indenture. If the aggregate principal amount of Notes surrendered
by Holders thereof exceeds the amount of Excess Proceeds, the Trustee shall
select the Notes to be purchased on a pro rata basis. Upon completion of such
offer to purchase, the amount of Excess Proceeds shall be reset at zero.

<PAGE>
    RESTRICTED PAYMENTS
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or
make any other payment or distribution on account of the Company's or any of its
Subsidiaries' Equity Interests (including, without limitation, any payment in
connection with any merger or consolidation involving the Company) or to the
direct or indirect holders of the Company's or any of its Subsidiaries' Equity
Interests in their capacity as such (other than dividends or distributions
payable in Equity Interests (other than Disqualified Stock) of the Company);
(ii) purchase, redeem or otherwise acquire or retire for value (including
without limitation, in connection with any merger or consolidation involving the
Company) any Equity Interests of the Company or any direct or indirect parent of
the Company or other Affiliate of the Company (other than any such Equity
Interests owned by the Company or any Wholly Owned Subsidiary of the Company);
(iii) make any payment on or with respect to, or purchase, redeem, defease or
otherwise acquire or retire for value any Indebtedness that is subordinated to
the Notes, except a payment of interest or principal at Stated Maturity; or (iv)
make any Restricted Investment (all such payments and other actions set forth in
clauses (i) through (iv) above being collectively referred to as "Restricted
Payments"), unless, at the time of and after giving effect to such Restricted
Payment:
 
    (a) no Default or Event of Default shall have occurred and be continuing or
       would occur as a consequence thereof; and
 
    (b) the Company would, at the time of such Restricted Payment and after
       giving pro forma effect thereto as if such Restricted Payment had been
       made at the beginning of the applicable four-quarter period, have been
       permitted to incur at least $1.00 of additional Indebtedness pursuant to
       the Fixed Charge Coverage Ratio test set forth in the first paragraph of
       the covenant described above under caption "-- Incurrence of Indebtedness
       and Issuance of Preferred Stock"; and
 
    (c) such Restricted Payment, together with the aggregate amount of all other
       Restricted Payments made by the Company and its Subsidiaries after the
       date of the Indenture (excluding Restricted Payments permitted by clauses
       (ii), (iii) and (iv) of the next succeeding paragraph), is less than the
       sum of (i) 50% of the Consolidated Net Income of the Company for the
       period (taken as one accounting period) from the beginning of the first
       fiscal quarter commencing after the date of the Indenture to the end of
       the Company's most recently ended fiscal quarter for which internal
       financial statements are available at the time of such Restricted Payment
       (or, if such Consolidated Net Income for such period is a deficit, less
       100% of such deficit), plus (ii) 100% of the aggregate net cash proceeds
       received by the Company from the issue or sale since the date of the
       Indenture of Equity Interests of the Company (other than Disqualified
       Stock) or of Disqualified Stock or debt securities of the Company that
       have been converted into such Equity Interests (other than Equity
       Interests (or Disqualified Stock or convertible debt securities) sold to
       a Subsidiary of the Company and other than Disqualified Stock or
       convertible debt securities that have been converted into Disqualified
       Stock), plus (iii) to the extent that any Restricted Investment that was
       made after the date of the Indenture is sold for cash or otherwise
       liquidated or repaid for cash, the lesser of (A) the cash return of
       capital with respect to such Restricted Investment (less the cost of
       disposition, if any) and (B) the initial amount of such Restricted
       Investment.
 
    The foregoing provisions will not prohibit (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
in exchange for, or out of the net cash proceeds of the substantially concurrent
sale (other than to a Subsidiary of the Company) of, other Equity Interests of
the Company (other than any Disqualified Stock); PROVIDED that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement, defeasance or other acquisition shall be excluded from clause (c)
(ii) of the preceding paragraph; (iii) the defeasance,
 
                                       72
<PAGE>
redemption, repurchase or other acquisition of subordinated Indebtedness with
the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness;
(iv) the payment of any dividend by a Subsidiary of the Company to the holders
of its common Equity Interests on a pro rata basis; and (v) the repurchase,
redemption or other acquisition or retirement for value of any Equity Interests
of the Company or any Subsidiary of the Company held by any member of the
Company's (or any of its Subsidiaries') management pursuant to any management
equity subscription agreement or stock option agreement; PROVIDED that the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $1.0 million in any twelve-month period and
$5.0 million in total and no Default or Event of Default shall have occurred and
be continuing immediately after such transaction.
 
    The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Subsidiary, as the
case may be, pursuant to the Restricted Payment. The fair market value of any
non-cash Restricted Payment shall be determined by the Board of Directors whose
resolution with respect thereto shall be delivered to the Trustee. Not later
than the date of making any Restricted Payment, the Company shall deliver to the
Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
the covenant "Restricted Payments" were computed, together with a copy of any
fairness opinion required by the Indenture.
 
    INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly, create, incur, issue, assume,
guarantee or otherwise become directly or indirectly liable, contingently or
otherwise, with respect to (collectively, "incur") any Indebtedness (including
Acquired Debt) and that the Company will not issue any Disqualified Stock and
will not permit any of its Subsidiaries to issue any shares of preferred stock;
PROVIDED, HOWEVER, that the Company may incur Indebtedness (including Acquired
Debt) or issue shares of Disqualified Stock if the Fixed Charge Coverage Ratio
for the Company's most recently ended four full fiscal quarters for which
internal financial statements are available immediately preceding the date on
which such additional Indebtedness is incurred or such Disqualified Stock is
issued would have been at least 2.0 to 1, determined on a pro forma basis
(including a pro forma application of the net proceeds therefrom), as if the
additional Indebtedness had been incurred, or the Disqualified Stock had been
issued, as the case may be, at the beginning of such four-quarter period.
 
    The provisions of the first paragraph of this covenant will not apply to the
incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):
 
    (i) the incurrence by the Company of Indebtedness and letters of credit
(with letters of credit being deemed to have a principal amount equal to the
maximum potential liability of the Company and its Subsidiaries thereunder)
under the New Credit Agreement and the incurrence by the Subsidiary Guarantors
of Guarantees thereof; PROVIDED that the aggregate principal amount of all
Indebtedness outstanding under the New Credit Agreement after giving effect to
such incurrence does not exceed $45.0 million less the aggregate amount of all
Net Proceeds of Asset Sales applied to permanently repay any such Indebtedness
or, in the case of any such revolving Indebtedness, permanently reduce
commitments therefor pursuant to the covenant described above under the caption
"-- Asset Sales";
 
    (ii) the incurrence by the Company or any of its Subsidiaries of Hedging
Obligations that are incurred for the purpose of fixing or hedging interest rate
risk with respect to any floating rate Indebtedness that is permitted by the
terms of this Indenture to be outstanding or that are incurred by the Company or
any of its Subsidiaries to protect against currency exchange rate risk in the
conduct of its operations;
 
    (iii) the incurrence by the Foreign Subsidiaries of Indebtedness in an
aggregate amount that, when combined with Existing Indebtedness of such Foreign
Subsidiaries (other than Indebtedness described in
 
                                       73
<PAGE>
clause (iv) below), does not exceed $6.5 million and the incurrence by the
Company of Guarantees of such Indebtedness;
 
    (iv) the incurrence by the Foreign Subsidiaries of Indebtedness in
connection with the issuance of completion bonds, performance guaranties or
letters of credit, and the incurrence by the Company of Guarantees thereof (with
such bonds, guaranties or letters of credit being deemed to have a principal
amount equal to the maximum potential liability of the Foreign Subsidiaries
thereunder) in an aggregate amount that, when combined with such Existing
Indebtedness of such Foreign Subsidiaries (other than Indebtedness described in
clause (iii) above), does not exceed $4.0 million;
 
    (v) the incurrence by the Company and its Subsidiaries of the Existing
Indebtedness;
 
    (vi) the incurrence by the Company of Indebtedness represented by the Notes
and the incurrence by the Subsidiary Guarantors of Indebtedness represented by
the Subsidiary Guarantees;
 
    (vii) the incurrence by the Company or any of its Subsidiaries of Permitted
Refinancing Indebtedness in exchange for, or the net proceeds of which are used
to refund, refinance or replace Indebtedness that was permitted by the Indenture
to be incurred;
 
    (viii) the incurrence by the Company or any of its Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Wholly
Owned Subsidiaries; PROVIDED, HOWEVER, that (i) if the Company is the obligor on
such Indebtedness, such Indebtedness is expressly subordinated to the prior
payment in full in cash of all Obligations with respect to the Notes and if a
Subsidiary Guarantor is the obligor on such Indebtedness, such Indebtedness is
expressly subordinated to the prior payment in full in cash of all Obligations
with respect to the Subsidiary Guarantees and (ii)(A) any subsequent issuance or
transfer of Equity Interests that results in any such Indebtedness being held by
a Person other than the Company or a Wholly Owned Subsidiary and (B) any sale or
other transfer of any such Indebtedness to a Person that is not either the
Company or a Wholly Owned Subsidiary shall be deemed, in each case, to
constitute an incurrence of such Indebtedness by the Company or such Subsidiary,
as the case may be;
 
    (ix) the incurrence by the Company or any of the Subsidiary Guarantors of
Indebtedness represented by Capital Lease Obligations, mortgage financings or
purchase money obligations, in each case incurred for the purpose of financing
all or any part of the purchase price or cost of construction or improvements of
property used in the business of the Company or such Subsidiary Guarantors, in
an aggregate principal amount not to exceed $5.0 million at any time
outstanding; and
 
    (x) the incurrence by the Company of additional Indebtedness in an aggregate
principal amount (or accreted value, as applicable) at any time outstanding,
including all Permitted Refinancing Indebtedness incurred to refund, refinance
or replace any other Indebtedness incurred pursuant to this clause (x), not to
exceed $15.0 million.
 
    For purposes of determining compliance with this covenant, in the event that
an item of Indebtedness meets the criteria of more than one of the categories of
Permitted Debt described in clauses (i) through (x) above or is entitled to be
incurred pursuant to the first paragraph of this covenant, the Company shall, in
its sole discretion, classify such item of Indebtedness in any manner that
complies with this covenant and such item of Indebtedness will be treated as
having been incurred pursuant to only one of such clauses or pursuant to the
first paragraph hereof. Any Indebtedness that may be incurred pursuant to this
covenant may be incurred under the New Credit Agreement.
 
    LIENS
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly, create, incur, assume or suffer to
exist any Lien on any asset now owned or hereafter acquired, or any income or
profits therefrom or assign or convey any right to receive income therefrom,
except Permitted Liens.
 
                                       74
<PAGE>
    DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, directly or indirectly, create or otherwise cause or suffer
to exist or become effective any encumbrance or restriction on the ability of
any Subsidiary to (i)(a) pay dividends or make any other distributions to the
Company or any of its Subsidiaries (1) on its Capital Stock or (2) with respect
to any other interest or participation in, or measured by, its profits, or (b)
pay any indebtedness owed to the Company or any of its Subsidiaries, (ii) make
loans or advances to the Company or any of its Subsidiaries or (iii) transfer
any of its properties or assets to the Company or any of its Subsidiaries,
except for such encumbrances or restrictions existing under or by reason of (a)
Existing Indebtedness as in effect on the date of the Indenture, (b) the New
Credit Agreement as in effect as of the date of the Indenture, and any
amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacements or refinancings thereof, PROVIDED that such amendments,
modifications, restatements, renewals, increases, supplements, refundings,
replacement or refinancings are no more restrictive in the aggregate with
respect to such dividend and other payment restrictions than those contained in
the New Credit Agreement as in effect on the date of the Indenture, (c) the
Indenture, the Notes and the Subsidiary Guarantees, (d) applicable law, (e) any
instrument regarding the sale, lease or purchase of any asset or governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Subsidiaries as in effect at the time of such acquisition (except to the extent
such Indebtedness was incurred in connection with or in contemplation of such
acquisition), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired, PROVIDED that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of the Indenture to
be incurred, (f) by reason of customary non-assignment provisions in licenses or
leases entered into in the ordinary course of business and consistent with past
practices, (g) purchase money obligations or Capital Lease Obligations for
property acquired in the ordinary course of business that impose restrictions of
the nature described in clause (iii) above on the property so acquired, or (h)
Permitted Refinancing Indebtedness, PROVIDED that the restrictions contained in
the agreements governing such Permitted Refinancing Indebtedness are no more
restrictive in the aggregate than those contained in the agreements governing
the Indebtedness being refinanced.
 
    LIMITATION ON LAYERING DEBT
 
    The Indenture provides that the Company will not incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the Notes. In addition, the Indenture provides
that the Subsidiary Guarantors will not incur, create, issue, assume, guarantee
or otherwise become liable for any Indebtedness that is subordinate or junior in
right of payment to any Senior Debt of the Subsidiary Guarantor and senior in
any respect in right of payment to the Subsidiary Guarantees.
 
    TRANSACTIONS WITH AFFILIATES
 
    The Indenture provides that the Company will not, and will not permit any of
its Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise
dispose of any of its properties or assets to, or purchase any property or
assets from, or enter into or make or amend any transaction, contract,
agreement, understanding, loan, advance or guarantee with, or for the benefit
of, any Affiliate (each of the foregoing, an "Affiliate Transaction"), unless
(i) such Affiliate Transaction is on terms that are at least as favorable as
those that could reasonably be expected to be obtained by the Company or the
relevant Subsidiary in a comparable transaction by the Company or such
Subsidiary with an unrelated Person and (ii) the Company delivers to the Trustee
(a) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $1.0 million, a
resolution of the Board of Directors set forth in an Officers' Certificate
certifying that such Affiliate Transaction complies with clause (i) above and
that such Affiliate Transaction has been approved by a majority of the
disinterested members of the Board
 
                                       75
<PAGE>
of Directors and (b) with respect to any Affiliate Transaction or series of
related Affiliate Transactions involving aggregate consideration in excess of
$5.0 million, an opinion as to the fairness to the Company of such Affiliate
Transaction from a financial point of view issued by an accounting, appraisal or
investment banking firm of national standing; PROVIDED that the following shall
not be deemed to be Affiliate Transactions: (s) transactions pursuant to the
Distribution Agreement, dated April 23, 1996, and the Technical Collaboration
Agreement, dated as of April 23, 1996, each between the Company or one of its
Subsidiaries and Yokogawa, to the extent that such transactions are on terms
that are at least as favorable as those that could reasonably be expected to be
obtained by the Company or the relevant Subsidiary in a comparable transaction
by the Company or such Subsidiary with an unrelated Person; (t) lease payments,
renewals and extensions under the lease agreement, dated June 29, 1996, between
the Company and Toyon Investments, a corporation controlled by Gooding, to the
extent that aggregate annual lease payments do not exceed $585,000 per year,
plus annual consumer price index adjustments, not to exceed 3% per annum; (u)
any payments or transactions made in accordance with, or that are authorized
under, the Stockholders Agreement, including the engagement or appointment of
Donaldson, Lufkin & Jenrette Securities Corporation as underwriter in connection
with an initial public offering; (v) the engagement or appointment by the
Company of Donaldson, Lufkin & Jenrette Securities Corporation as its financial
advisor, investment banking firm or arranger with respect to the New Credit
Agreement, to the extent that the fees and expenses under such engagement are
reasonable and customary for such engagements; (w) the exercise by Gooding of
his option to purchase the Company's executive offices at 11995 El Camino Road,
San Diego, California including all the leasehold improvements and fixed assets
therein pursuant to the terms set forth in the resolution of the Company adopted
on September 19, 1995; (x) any employment agreement entered into by the Company
or any of its Subsidiaries in the ordinary course of business and consistent
with the past practice of the Company or such Subsidiary; (y) transactions
between or among the Company and/or its Subsidiaries; and (z) Restricted
Payments that are permitted by the provisions of the Indenture described above
under the caption "-- Restricted Payments."
 
    ADDITIONAL SUBSIDIARY GUARANTEES
 
    The Indenture provides that if the Company or any of its Subsidiaries shall
acquire or create another Subsidiary (other than a Foreign Subsidiary) after the
date of the Indenture, then such newly acquired or created Subsidiary shall
execute a Subsidiary Guarantee and deliver an opinion of counsel, in accordance
with the terms of the Indenture.
 
    The Indenture also provides that 100% of the Capital Stock of all Foreign
Subsidiaries must be owned directly or indirectly by the Company and that the
Company will not allow its Foreign Subsidiaries to acquire or create any
Subsidiaries.
 
    REPORTS
 
    The Indenture provides that, whether or not required by the rules and
regulations of the Securities and Exchange Commission (the "Commission"), so
long as any Notes are outstanding, the Company will furnish to the Holders of
Notes (i) all quarterly and annual financial information that would be required
to be contained in a filing with the Commission on Forms 10-Q and 10-K if the
Company were required to file such Forms, including a "Management's Discussion
and Analysis of Financial Condition and Results of Operations" and, with respect
to the annual information only, a report thereon by the Company's certified
independent auditors and (ii) all current reports that would be required to be
filed with the Commission on Form 8-K if the Company were required to file such
reports. In addition, whether or not required by the rules and regulations of
the Commission, the Company will file a copy of all such information and reports
with the Commission for public availability (unless the Commission will not
accept such a filing) and make such information available to securities analysts
and prospective investors upon request. In addition, the Company has agreed
that, for so long as any Notes remain outstanding, it will furnish to the
Holders and to
 
                                       76
<PAGE>
prospective purchasers designated by such Holders, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.
 
    MERGER, CONSOLIDATION OR SALE OF ASSETS
 
    The Indenture provides that the Company may not consolidate or merge with or
into (whether or not the Company is the surviving corporation), or sell, assign,
transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets in one or more related transactions, to another
corporation, Person or entity unless (i) the Company is the surviving
corporation or the entity or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United States,
any state thereof or the District of Columbia; (ii) the entity or Person formed
by or surviving any such consolidation or merger (if other than the Company) or
the entity or Person to which such sale, assignment, transfer, lease, conveyance
or other disposition shall have been made assumes all the obligations of the
Company under the Notes and the Indenture pursuant to a supplemental indenture
in a form reasonably satisfactory to the Trustee; (iii) immediately after such
transaction no Default or Event of Default exists; and (iv) except in the case
of a merger of the Company with or into a Wholly Owned Subsidiary of the
Company, the Company or the entity or Person formed by or surviving any such
consolidation or merger (if other than the Company), or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made (A) will have Consolidated Net Worth immediately after the transaction
equal to or greater than the Consolidated Net Worth of the Company immediately
preceding the transaction and (B) will, after giving pro forma effect thereto as
if such transaction had occurred at the beginning of the applicable four-quarter
period, be permitted to incur at least $1.00 of additional Indebtedness pursuant
to the Fixed Charge Coverage Ratio test set forth in the first paragraph of the
covenant described above under the caption
"-- Incurrence of Indebtedness and Issuance of Preferred Stock."
 
EVENTS OF DEFAULT AND REMEDIES
 
    The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on, or
Liquidated Damages with respect to, the Notes (whether or not prohibited by the
subordination provisions of the Indenture); (ii) default in payment when due of
the principal of or premium, if any, on the Notes (whether or not prohibited by
the subordination provisions of the Indenture); (iii) failure by the Company to
comply with the provisions described under the captions "-- Certain Covenants --
Change of Control," "-- Asset Sales," "-- Restricted Payments" or "-- Incurrence
of Indebtedness and Issuance of Preferred Stock"; (iv) failure by the Company
for 60 days after notice to comply with any of its other agreements in the
Indenture or the Notes; (v) except as permitted by the Indenture, any Subsidiary
Guarantee shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acing on behalf of any Subsidiary Guarantor,
shall deny or disaffirm its obligations under its Subsidiary Guarantee; (vi)
default under any mortgage, indenture or instrument under which there may be
issued or by which there may be secured or evidenced any Indebtedness for money
borrowed by the Company or any of its Subsidiaries (or the payment of which is
guaranteed by the Company or any of its Subsidiaries) whether such Indebtedness
or guarantee now exists, or is created after the date of the Indenture, which
default (a) is caused by a failure to pay principal when due at final stated
maturity (a "Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, together with the principal amount of any other
such Indebtedness under which there has been a Payment Default or the maturity
of which has been so accelerated, aggregates $7.5 million or more; (vii) failure
by the Company or any of its Subsidiaries to pay final judgments aggregating in
excess of $7.5 million, which judgments are not paid, discharged or stayed for a
period of 60 days; and (viii) certain events of bankruptcy or insolvency with
respect to the Company or any of its Significant Subsidiaries.
 
                                       77
<PAGE>
    If any Event of Default occurs and is continuing, the Trustee or the Holders
of at least 25% in principal amount of the then outstanding Notes may declare
all the Notes to be due and payable by notice in writing to the Company and the
Trustee specifying the respective Event of Default and that it is a notice of
acceleration (the "Acceleration Notice"), and the same (i) shall become
immediately due and payable or (ii) if there are any amounts outstanding under
the New Credit Agreement, shall become immediately due and payable upon the
first to occur of an acceleration under the New Credit Agreement or five
Business Days after receipt by the Company and the Representative under the New
Credit Agreement of such Acceleration Notice but only if such Event of Default
is then continuing. Notwithstanding the foregoing, in the case of an Event of
Default arising from certain events of bankruptcy or insolvency, with respect to
the Company, any Significant Subsidiary or any group of Subsidiaries that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of the
then outstanding Notes may direct the Trustee in its exercise of any trust or
power. In the event of a declaration of acceleration of the Notes because an
Event of Default has occurred and is continuing as a result of the acceleration
of any Indebtedness described in clause (vi) of the preceding paragraph, the
declaration of acceleration of the Notes shall be automatically annulled if the
holders of any Indebtedness described in clause (vi) have rescinded the
declaration of acceleration in respect of such Indebtedness within 30 days of
the date of such declaration and if (i) the annulment of the acceleration of the
Notes would not conflict with any judgment or decree of a court of competent
jurisdiction, and (ii) all existing Events of Default, except nonpayment of
principal or interest or Liquidated Damages on the Notes that became due solely
because of the acceleration of the Notes, have been cured or waived. The Trustee
may withhold from Holders of the Notes notice of any continuing Default or Event
of Default (except a Default or Event of Default relating to the payment of
principal or interest) if it determines that withholding notice is in their
interest.
 
    In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the Notes. If an Event of Default occurs prior to June
15, 2002 by reason of any willful action (or inaction) taken (or not taken) by
or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the Notes prior to June 15, 2002, then the premium specified in
the Indenture shall also become immediately due and payable to the extent
permitted by law upon the acceleration of the Notes.
 
    The Holders of a majority in aggregate principal amount of the Notes then
outstanding by notice to the Trustee may on behalf of the Holders of all of the
Notes waive any existing Default or Event of Default and its consequences under
the Indenture except a continuing Default or Event of Default in the payment of
interest on, or the principal of, the Notes.
 
    The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND STOCKHOLDERS
 
    No director, officer, employee, incorporator or stockholder of the Company
or any Subsidiary Guarantor, as such, shall have any liability for any
obligations of the Company or any Subsidiary Guarantor under the Notes, the
Indenture or any Subsidiary Guarantee or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder of Notes by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for issuance of the Notes. Such waiver may not be
effective to waive liabilities under the federal securities laws and it is the
view of the Commission that such a waiver is against public policy.
 
                                       78
<PAGE>
LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
    The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding Notes ("Legal
Defeasance") except for (i) the rights of Holders of outstanding Notes to
receive payments in respect of the principal of, premium, if any, and interest
and Liquidated Damages on such Notes when such payments are due from the trust
referred to below, (ii) the Company's obligations with respect to the Notes
concerning issuing temporary Notes, registration of Notes, mutilated, destroyed,
lost or stolen Notes and the maintenance of an office or agency for payment and
money for security payments held in trust, (iii) the rights, powers, trusts,
duties and immunities of the Trustee, and the Company's obligations in
connection therewith and (iv) the Legal Defeasance provisions of the Indenture.
In addition, the Company may, at its option and at any time, elect to have the
obligations of the Company released with respect to certain covenants that are
described in the Indenture ("Covenant Defeasance") and thereafter any omission
to comply with such obligations shall not constitute a Default or Event of
Default with respect to the Notes. In the event Covenant Defeasance occurs,
certain events (not including non-payment, bankruptcy, receivership,
rehabilitation and insolvency events) described under "Events of Default" will
no longer constitute an Event of Default with respect to the Notes.
 
    In order to exercise either Legal Defeasance or Covenant Defeasance, (i) the
Company must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and Liquidated Damages on
the outstanding Notes on the stated maturity or on the applicable redemption
date, as the case may be, and the Company must specify whether the Notes are
being defeased to maturity or to a particular redemption date; (ii) in the case
of Legal Defeasance, the Company shall have delivered to the Trustee an opinion
of counsel in the United States reasonably acceptable to the Trustee confirming
that (A) the Company has received from, or there has been published by, the
Internal Revenue Service a ruling or (B) since the date of the Indenture, there
has been a change in the applicable federal income tax law, in either case to
the effect that, and based thereon such opinion of counsel shall confirm that,
the Holders of the outstanding Notes will not recognize income, gain or loss for
federal income tax purposes as a result of such Legal Defeasance and will be
subject to federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such Legal Defeasance had not
occurred; (iii) in the case of Covenant Defeasance, the Company shall have
delivered to the Trustee an opinion of counsel in the United States reasonably
acceptable to the Trustee confirming that the Holders of the outstanding Notes
will not recognize income, gain or loss for federal income tax purposes as a
result of such Covenant Defeasance and will be subject to federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such Covenant Defeasance had not occurred; (iv) no Default or Event
of Default shall have occurred and be continuing on the date of such deposit
(other than a Default or Event of Default resulting from the borrowing of funds
to be applied to such deposit) or insofar as Events of Default from bankruptcy
or insolvency events are concerned, at any time in the period ending on the 91st
day after the date of deposit; (v) such Legal Defeasance or Covenant Defeasance
will not result in a breach or violation of, or constitute a default under the
New Credit Agreement or any other material agreement or instrument (other than
the Indenture) to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound; (vi) the Company must
deliver to the Trustee an Officers' Certificate stating that the deposit was not
made by the Company with the intent of preferring the Holders of Notes over the
other creditors of the Company with the intent of defeating, hindering, delaying
or defrauding creditors of the Company or others; and (vii) the Company must
deliver to the Trustee an Officers' Certificate and an opinion of counsel, each
stating that all conditions precedent provided for relating to the Legal
Defeasance or the Covenant Defeasance have been complied with.
 
                                       79

TRANSFER AND EXCHANGE
 
    A Holder may transfer or exchange Notes in accordance with the Indenture.
The Registrar and the Trustee may require a Holder, among other things, to
furnish appropriate endorsements and transfer documents and the Company may
require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Company is not required to transfer or exchange any Note selected
for redemption. Also, the Company is not required to transfer or exchange any
Note for a period of 15 days before a selection of Notes to be redeemed.
 
    The registered Holder of a Note will be treated as the owner of it for all
purposes.
 
AMENDMENT, SUPPLEMENT AND WAIVER
 
    Except as provided in the next two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented with the consent of the Holders of at
least a majority in principal amount of the Notes then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or
tender offer or exchange offer for, Notes), and any existing default or
compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in principal amount of the then
outstanding Notes (including consents obtained in connection with a tender offer
or exchange offer for Notes).
 
    Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any Notes held by a non-consenting Holder): (i) reduce the
principal amount of Notes whose Holders must consent to an amendment, supplement
or waiver, (ii) reduce the principal of or change the fixed maturity of any Note
or alter the provisions with respect to the redemption of the Notes (other than
provisions relating to the covenants described above under the caption "--
Certain Covenants -- Change of Control" and "-- Asset Sales"), (iii) reduce the
rate of or change the time for payment of interest on any Note, (iv) waive a
Default or Event of Default in the payment of principal of or premium, if any,
or interest on the Notes (except a rescission of acceleration of the Notes by
the Holders of at least a majority in aggregate principal amount of the Notes
and a waiver of the payment default that resulted from such acceleration), (v)
make any Note payable in money other than that stated in the Notes, (vi) make
any change in the provisions of the Indenture relating to waivers of past
Defaults or the rights of Holders of Notes to receive payments of principal of
or premium, if any, or interest on the Notes, (vii) waive a redemption payment
with respect to any Note (other than a payment required by the covenants
described above under the captions "-- Certain Covenants -- Change of Control"
or "-- Asset Sales") or (viii) make any change in the foregoing amendment and
waiver provisions. In addition, any amendment to the provisions of Article 10 of
the Indenture (which relate to subordination) will require the consent of the
Holders of at least 75% in aggregate principal amount of the Notes then
outstanding if such amendment would adversely affect the rights of Holders of
Notes.
 
    Notwithstanding the foregoing, without the consent of any Holder of Notes,
the Company and the Trustee may amend or supplement the Indenture or the Notes
to cure any ambiguity, defect or inconsistency, to provide for uncertificated
Notes in addition to or in place of certificated Notes, to provide for the
assumption of the Company's obligations to Holders of Notes in the case of a
merger or consolidation, to make any change that would provide any additional
rights or benefits to the Holders of Notes or that does not adversely affect the
legal rights under the Indenture of any such Holder, or to comply with
requirements of the Commission in order to effect or maintain the qualification
of the Indenture under the Trust Indenture Act.
 
                                       80
<PAGE>
CONCERNING THE TRUSTEE
 
    The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions; however, if it acquires any conflicting interest it must eliminate
such conflict within 90 days, apply to the Commission for permission to continue
or resign.
 
    The Holders of a majority in principal amount of the then outstanding Notes
will have the right to direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee, subject to
certain exceptions. The Indenture provides that in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his own affairs. Subject to such provisions, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request of any Holder of Notes, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.
 
BOOK-ENTRY, DELIVERY AND FORM
 
    The New Notes will be issued in the form of a Global Note (a "Global Note").
Each Global Note will be deposited with, or on behalf of, The Depositary Trust
Company ("DTC") and registered in the name of DTC or its nominee. Except as set
forth below, each Global Note may be transferred, in whole or in part, only to
DTC or another nominee of DTC. Investors may hold their beneficial interest in a
Global Note directly through DTC if they are participants in such system or
indirectly through organizations which are participants in such system.
 
    DTC is a limited-purpose trust company that was created to hold securities
for its participating organizations (collectively, the "Participants") and to
facilitate the clearance and settlement of transactions in such securities
between Participants through electronic book-entry changes in accounts of its
Participants. The Participants include securities brokers and dealers (including
the Initial Purchaser), banks and trust companies, clearing corporations and
certain other organizations. Access to DTC's system is also available to other
entities such as banks, brokers, dealers and trust companies (collectively, the
"Indirect Participants") that clear through or maintain a custodial relationship
with a Participant, either directly or indirectly. Persons who are not
Participants may beneficially own securities held by or on behalf of DTC only
through the Participants or Indirect Participants.
 
    Upon the issuance of the Global Notes, DTC will credit the accounts of
Participants designated by the Initial Purchasers with portions of the principal
amount of the Global Notes. Ownership of the Notes evidenced by the Global Notes
will be shown on, and the transfer of ownership thereof will be effected only
through, records maintained by DTC (with respect to the interest of
Participant), the Participants and the Indirect Participants. Prospective
purchasers are advised that the laws of some states require that certain persons
take physical delivery in definitive form of securities they own. Consequently,
the ability to transfer Notes evidenced by the Global Notes will be limited to
such extent.
 
    So long as the nominee of DTC is the registered owner or holder of any
Notes, such nominee will be considered the sole owner or Holder under the
Indenture of any Notes evidenced by the Global Notes. Beneficial owners of Notes
evidenced by a Global Note will not be considered the owners or Holders thereof
under the Indenture for any purpose, including with respect to the giving of any
directions, instructions or approvals to the Trustee thereunder. Neither the
Company nor the Trustee will have any responsibility or liability for any aspect
of the records of DTC or for maintaining, supervising or reviewing any records
of DTC relating to the Notes. No beneficial owner of an interest in any Global
Note will be able to transfer that interest except in accordance with DTC's
procedures in addition to those provided for under the Indenture.
 
                                       81
<PAGE>
    Payments in respect of the principal of, premium, if any, interest and
Liquidated Damages, if any, on any Notes registered in the name of the nominee
of DTC on the applicable record date will be payable by the Trustee to or at the
direction of DTC or its nominee in its capacity as the registered Holder under
the Indenture. Under the terms of the Indenture, the Company and the Trustee may
treat the person in whose names Notes, including the Global Notes, are
registered as the owners thereof for the purpose of receiving such payments.
Consequently, neither the Company, the Trustee nor any paying agent of the
Company has or will have any responsibility or liability for the payment of such
amounts to beneficial owners of Notes (including principal, premium, if any,
interest and Liquidated Damages, if any). The Company believes, however, that it
is currently the policy of DTC or its nominee, to immediately credit the
accounts of the relevant Participants with such payments, in amounts
proportionate to their respective holdings of beneficial interests in the
relevant security as shown on the records of DTC or its nominee. Payments by the
Participants and the Indirect Participants to the beneficial owners of Notes
will be governed by standing instructions and customary practice and will be the
responsibility of the Participants or the Indirect Participants.
 
CERTIFICATED NOTES
 
    If (i) the Company notifies the Trustee in writing that DTC or its nominee
is no longer willing or able to act as a depository and the Company is unable to
locate a qualified successor within 90 days or (ii) the Company, at its option,
notifies the Trustee in writing that it elects to cause the issuance of Notes in
the form of Certificated Securities under the Indenture, then, upon surrender by
DTC or its nominee of its Global Notes, Notes in such form will be issued to
each person that DTC or its nominee identify as being the beneficial owner of
the corresponding Notes.
 
    Neither the Company nor the Trustee will be liable for any delay by a holder
of a Global Note or DTC or its nominee in identifying the beneficial owners of
Notes and the Company and the Trustee may conclusively rely on, and will be
protected in relying on, instructions from DTC or its nominee for all purposes.
 
REGISTRATION RIGHTS; LIQUIDATED DAMAGES
 
    In connection with the sale of the Old Notes, the Company and the Initial
Purchaser entered into the Registration Rights Agreement on the Issue Date.
Pursuant to the Registration Rights Agreement, the Company agreed to file with
the SEC a registration statement on the appropriate form under the Securities
Act with respect to the New Notes (the "Exchange Offer Registration Statement").
The Exchange Offer is being made to satisfy the contractual obligations of the
Company under the Registration Rights Agreement and the Registration Statement
of which this Prospectus forms a part in the Exchange Offer Registration
Statement. If (i) the Company is not required to file the Exchange Offer
Registration Statement or permitted to consummate the Exchange Offer because the
Exchange Offer is not permitted by applicable law or SEC policy or (ii) any
Holder of Transfer Restricted Securities notifies the Company within the
specified time period that (A) it is prohibited by law or SEC policy from
participating in the Exchange Offer or (B) that it may not resell the New Notes
acquired by it in the Exchange Offer to the public without delivering a
prospectus and the prospectus contained in the Exchange Offer Registration
Statement is not appropriate or available for such resales or (C) that it is a
broker-dealer and owns Old Notes acquired directly from the Company or an
affiliate of the Company, the Company will file with the SEC a shelf
registration statement (the "Shelf Registration Statement") to cover resales of
the Notes by the Holders thereof who satisfy certain conditions relating to the
provision of information in connection with the Shelf Registration Statement.
The Company will use its best efforts to cause the applicable registration
statement to be declared effective as promptly as possible by the SEC. For
purposes of the foregoing, "Transfer Restricted Securities" means each Old Note
until (i) the date on which such Note has been exchanged by a person other than
a broker-dealer for a New Note in the Exchange Offer, (ii) following the
exchange by a broker-dealer in the Exchange Offer of a Old Note for a New Note,
the
 
                                       82
<PAGE>
date on which such New Note is sold to a purchaser who receives from such
broker-dealer on or prior to the date of such sale a copy of this Prospectus,
(iii) the date on which such Note has been effectively registered under the
Securities Act and disposed of in accordance with the Shelf Registration
Statement or (iv) the date on which such Note is distributed to the public
pursuant to Rule 144 under the Act.
 
    The Registration Rights Agreement provides that (i) the Company will file an
Exchange Offer Registration Statement with the SEC on or prior to 60 days after
the Issue Date, (ii) the Company will use its best efforts to have the Exchange
Offer Registration Statement declared effective by the SEC on or prior to 120
days after the Issue Date, (iii) unless the Exchange Offer would not be
permitted by applicable law or SEC policy, the Company will commence the
Exchange Offer and use its best efforts to issue on or prior to 45 business days
after the date on which the Exchange Offer Registration Statement was declared
effective by the SEC, New Notes in exchange for all Old Notes tendered prior
thereto in the Exchange Offer and (iv) if obligated to file the Shelf
Registration Statement, the Company will use its best efforts to file the Shelf
Registration Statement with the SEC on or prior to 60 days after such filing
obligation arises (and in any event within 120 days after the Issue Date) and to
cause the Shelf Registration to be declared effective by the SEC on or prior to
120 days after such filing obligation arises. If (a) the Company fails to file
any of the Registration Statements required by the Registration Rights Agreement
on or before the date specified for such filing, (b) any of such Registration
Statements is not declared effective by the SEC on or prior to the date
specified for such effectiveness (the "Effectiveness Target Date"), (c) the
Company fails to consummate the Exchange Offer within 45 business days of the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement, or (d) the Shelf Registration Statement or the Exchange Offer
Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (a) through (d) above a "Registration Default"),
then the Company will pay Liquidated Damages to each Holder of Old Notes, with
respect to the first 90-day period immediately following the occurrence of such
Registration Default in an amount equal to $.05 per week per $1,000 principal
amount of Old Notes held by such Holder. The amount of the Liquidated Damages
will increase by an additional $.05 per week per $1,000 principal amount of Old
Notes with respect to each subsequent 90-day period until all Registration
Defaults have been cured, up to a maximum amount of Liquidated Damages of $.50
per week per $1,000 principal amount of Old Notes. All accrued Liquidated
Damages will be paid by the Company to the Global Note Holder by wire transfer
of immediately available funds or by federal funds check and to Holders of
Certificated Securities by wire transfer to the accounts specified by them or by
mailing checks to their registered addresses if no such accounts have been
specified. Following the cure of all Registration Defaults, the accrual of
Liquidated Damages will cease.
 
    Holders of Old Notes will be required to make certain representations to the
Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver information to
be used in connection with the Shelf Registration Statement and to provide
comments on the Shelf Registration Statement within the time periods set forth
in the Registration Rights Agreement in order to have their Notes included in
the Shelf Registration Statement and benefit from the provisions regarding
Liquidated Damages set forth above. See "The Exchange Offer."

                       DESCRIPTION OF OTHER INDEBTEDNESS
 
NEW CREDIT AGREEMENT
 
   
    In connection with the Recapitalization Transactions, the Company entered
into a New Credit Agreement with Fleet National Bank, as Administrative Agent,
DLJ Capital Funding, Inc. ("DLJCF"), as Syndication Agent, and the several
lenders named therein. The following summary of the material terms of the New
Credit Agreement does not purport to be complete and is qualified in its
entirety by reference to the New Credit Facility, a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
New Credit Agreement provides for a five-year and six month term loan in the
principal amount of $25.0 million and a five year and six month revolving credit
facility providing for borrowings of up to $20.0 million, which includes a
swingline facility. The revolving credit facility under the New Credit Agreement
provides for up to an aggregate of $7.5 million of borrowings in British pounds,
French francs and Deutsche marks. The Company's obligations under the New Credit
Agreement constitute Senior Debt with respect to the Notes.
    
 
    PRINCIPAL PAYMENTS.  The term loan facility is subject to quarterly
amortization commencing in September 1998, in the following aggregate annual
amounts for fiscal years ending September 30: 1998 -- $1.0 million; 1999 --
$4.25 million; 2000 -- $5.25 million; 2001 -- $6.25 million; 2002 -- $6.75
million; and for the three months ending December 31, 2002 -- $1.5 million.
 
    INTEREST RATE.  Indebtedness under the New Credit Agreement bears interest,
at the option of the Company, at either (i) the Base Rate (as defined in the New
Credit Agreement) plus 1.5%, or (ii) at the reserve-adjusted Euro-Dollar Rate
(as defined in the New Credit Agreement) plus 2.5%, subject to reduction upon
achievement of certain performance levels and/or credit ratios. Loans under the
swingline facility bear interest at the Base Rate plus 1.5%.
 
    GUARANTEES AND SECURITY.  All current and future domestic subsidiaries of
the Company unconditionally guarantee the obligations under the New Credit
Agreement. In addition, all loans are secured by a lien on substantially all
existing and after-acquired property of the Company and its current and future
domestic subsidiaries, including a pledge of 100% of the stock of all domestic
subsidiaries of the Company, 65% of the stock of all foreign subsidiaries of the
Company and all intercompany loans from the Company to the Foreign Subsidiaries.
 
    COVENANTS.  The New Credit Agreement contains various affirmative, negative
and financial covenants, including, without limitation; (i) limitations on other
indebtedness, liens, investments, leases and guarantees; (ii) limitations on
redemptions and prepayments of the Notes and other junior debt prior to the
stated maturity thereof; (iii) limitation on mergers, acquisitions and sales of
assets; and (iv) a minimum EBITDA requirement, fixed charge coverage ratio
requirement, a minimum net worth test and a maximum leverage ratio test.
 
    EVENTS OF DEFAULT.  Events of default under the New Credit Agreement include
various events of default customary for such type of agreement. Without
limitation, a failure to make payments when due, noncompliance with covenants
and breaches of representations and warranties, payment defaults on other debt
and a change of control of the Company constitute an event of default.
 
OTHER DEBT
 
    Wavetek U.S. Inc. had a Business Loan Agreement (the "Existing U.S. Credit
Agreement") with a bank providing for revolving line of credit borrowings of up
to $4.0 million through January 1998. The Existing Credit Agreement was
terminated as part of the Recapitalization Transactions.
 
    The Company's subsidiaries in the United Kingdom, France, Germany and
Austria have agreements with banks providing for short-term revolving advances
and overdraft facilities in an aggregate total amount of approximately $6.5
million. In addition, the bank agreements with such subsidiaries also provide
 
                                       92
<PAGE>
for issuance of letters of credit and bank guarantees in an aggregate total
amount of approximately $4.0 million. At June 30, 1997, an aggregate amount of
$3.4 million had been borrowed under these facilities. Revolving borrowings
under these agreements bear interest at variable rates ranging from 4.2% to 8.4%
as of June 30, 1997. These bank agreements also provide for long-term borrowings
and are generally secured by the assets of the local subsidiary and the
guarantee of the Company. Most of these agreements also provide for the issuance
of letters of credit and bank guarantees. At June 30, 1997, the Company and its
foreign subsidiaries were contingently liable for outstanding letters of credit
and bank guarantees aggregating $2.1 million. Borrowings under the Company's
revolving bank agreements have been classified as "Notes payable to banks" in
the Company's Consolidated Financial Statements due to the short-term nature of
the revolving advances taken under these agreements.
 
    In connection with the October 1994 acquisition of its Telecom business, the
Company has a promissory note payable to Schlumberger in the amount of 5.2
million French francs ($0.9 million at June 30, 1997). The note is unsecured and
the full principal balance is payable in January 1998. Interest is payable
quarterly at PIBOR plus 0.50% (3.871% at June 30, 1997).
 
    In fiscal 1995, the Company sold its facility in Indianapolis to a third
party investor. In connection with this sale, the Company entered a master lease
agreement with the buyer, under which the Company leased back the facility for a
period of 20 years for an annual rent of $473,000, subject to annual adjustments
based on changes in the consumer price index, not to exceed 3% per annum. In
December 1994, the Company subleased a portion of this facility to a third party
for five years for an annual base rent and common area expense reimbursement of
$387,000. Because of the significance of the sublease in relation to the
Company's master lease of the facility, generally accepted accounting principles
require that the transaction be recorded as a financing transaction, whereby the
building remains on the Company's balance sheet in an amount equal to the net
proceeds from the sale and an offsetting long-term financing obligation has been
recorded. As of June 30, 1997, this financing obligation was $4.1 million.

                               VALIDITY OF NOTES
 
    The validity of the Notes offered hereby will be passed upon for the Company
by Sullivan & Cromwell, Los Angeles, California.

    The consolidated financial statements of Wavetek Corporation as of September
30, 1995 and 1996, and for each of the three years in the period ended September
30, 1996, appearing in this Prospectus and Registration Statement have been
audited by Ernst & Young LLP, independent auditors, as set forth in their report
thereon appearing elsewhere herein, and are included in reliance upon such
report given upon the authority of such firm as experts in accounting and
auditing.
 
                              PLAN OF DISTRIBUTION
 
    The Company is making the Exchange Offer in reliance on the position of the
staff of the Division of Corporation Finance of the Commission as set forth in
certain interpretive letters addressed to third parties in other transactions.
Based on these interpretations by the staff of the Division of Corporation
Finance, and subject to the two immediately following sentences, the Company
believes that New Notes issued pursuant to this Exchange Offer in exchange for
Old Notes may be offered for resale, resold and otherwise transferred by a
holder thereof (other than a holder who is a broker-dealer) without further
compliance with the registration and prospectus delivery requirements of the
Securities Act, provided that such New Notes are acquired in the ordinary course
of such holder's business and that such holder is not participating, and has no
arrangement or understanding with any person to participate, in a distribution
(within the meaning of the Securities Act) of such New Notes. However, any
holder of Old Notes who is an "affiliate" of the Company within the meaning of
Rule 405 under the Securities Act (an "Affiliate") or who intends to participate
in the Exchange Offer for the purpose of distributing New Notes, or any broker-
dealer who purchased Old Notes from the Company to resell pursuant to Rule 144A
or any other available exemption under the Securities Act, (i) will not be able
to rely on the interpretations of the staff of the Division of Corporation
Finance of the Commission set forth in the above-mentioned interpretive letters,
(ii) will not be permitted or entitled to tender such Old Notes in the Exchange
Offer and (iii) must comply with the registration and prospectus delivery
requirements of the Securities Act in connection with any sale or other transfer
of such Old Notes unless such sale is made pursuant to an exemption from such
requirements. In addition, as described below, broker-dealers ("Participating
Broker-Dealers") must deliver a prospectus meeting the requirements of the
Securities Act in connection with any resales of New Notes.
 
    Each holder of Old Notes who wishes to exchange Old Notes for New Notes in
the Exchange Offer will be required to represent that (i) it is not an
Affiliate, (ii) any New Notes to be received by it are being acquired in the
ordinary course of its business, (iii) it has no arrangement or understanding
with any person to participate in a distribution (within the meaning of the
Securities Act) of such New Notes and (iv) if such holder is not a
broker-dealer, such holder is not engaged in, and does not intend to engage in,
a distribution (within the meaning of the Securities Act) of such New Notes.
Each Participating Broker-Dealer must acknowledge that it acquired the Old Notes
for its own account as the result of market-making activities or other trading
activities and must agree that it will deliver a prospectus meeting the
requirements of the Securities Act in connection with any resale of such New
Notes. The Letter of Transmittal states that by so acknowledging and by
delivering a prospectus, a Participating Broker-Dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
Based on the position taken by the staff of the Division of Corporation Finance
of the Commission in the interpretive letters referred to above, the Company
believes that Participating Broker-Dealers may fulfill their prospectus delivery
requirements with respect to the New Notes received upon exchange of such Old
Notes (other than Old Notes which represent an unsold allotment from the
original sale of the Old Notes) with a prospectus meeting the requirements of
the Securities Act, which may be the prospectus prepared
 
                                       94
<PAGE>
for an exchange offer so long as it contains a description of the plan of
distribution with respect to the resale of such New Notes. Accordingly, this
Prospectus, as it may be amended or supplemented from time to time, may be used
by a Participating Broker-Dealer during the period referred to below in
connection with resales of New Notes received in exchange for Old Notes where
such Old Notes were acquired by such Participating Broker-Dealer for its own
account as a result of market-making or other trading activities. The Company
has agreed that this Prospectus, as it may be amended or supplemented from time
to time, may be used by a Participating Broker-Dealer in connection with resales
of such New Notes for a period ending one year from the date on which the
Exchange Offer Registration Statement is declared effective (subject to
extension under certain limited circumstances). Any person, including any
Participating Broker-Dealer, who is an Affiliate may not rely on such
interpretive letters and must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any resale
transaction. Gooding, an Affiliate of the Company, is the beneficial owner of
$5,000,000 aggregate principal amount of Old Notes. This Prospectus may be used
by Gooding in connection with resales of such Old Notes.
 
    In that regard, each Participating Broker-Dealer who surrenders Old Notes
pursuant to the Exchange Offer will be deemed to have agreed, by execution of
the Letter of Transmittal or delivery of an Agent's Message in lieu thereof,
that, upon receipt of notice from the Company of the occurrence of any event or
the discovery of any fact which makes any statement contained or incorporated by
reference in this Prospectus untrue in any material respect or which causes this
Prospectus to omit to state a material fact necessary in order to make the
statements contained or incorporated by reference herein, in light of the
circumstances under which they were made, not misleading or of the occurrence of
certain other events specified in the Registration Rights Agreement, such
Participating Broker-Dealer will forthwith discontinue the disposition of New
Notes pursuant to this Prospectus until the Company has amended or supplemented
this Prospectus and has furnished copies of the amended or supplemented
Prospectus to such Participating Broker-Dealer, or the Company has given notice
that the sale of the New Notes may be resumed, as the case may be.
 
    The Company will not receive any cash proceeds from the issuance of the New
Notes offered hereby. New Notes received by broker-dealers for their own
accounts may be sold from time to time in one or more transactions in the
over-the-counter market, in negotiated transactions, through the writing of
options on the New Notes or a combination of such methods of resale, at market
prices prevailing at the time of resale at prices related to such prevailing
market prices or at negotiated prices. Any such resale may be made directly to
purchasers or to or through brokers or dealers who may receive compensation in
the form of commissions or concessions from any such broker-dealer and/or the
purchasers of any such New Notes. Any broker-dealer that resells New Notes that
were received by it for its own account in connection with the Exchange Offer
and any broker or dealer that participates in a distribution of such New Notes
may be deemed to be an "underwriter" within the meaning of the Securities Act,
and any profit on any such resale of New Notes may be deemed to be underwriting
compensation under the Securities Act. The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
Wavetek Corporation
 
    We have audited the accompanying consolidated balance sheets of Wavetek
Corporation as of September 30, 1996 and 1995, and the related consolidated
statements of income, stockholders' equity and cash flows for each of the three
years in the period ended September 30, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Wavetek Corporation at September 30, 1996 and 1995, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended September 30, 1996, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1996 AND PERTAINING TO JUNE 30, 1997
 
     AND THE NINE-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
 
    ORGANIZATION
 
    Wavetek Corporation ("the Company") is a leading global designer,
manufacturer and distributor of a broad range of electronic test instruments,
with a primary focus on application-specific instruments for testing voice,
video and data communications equipment and networks. The Company also designs,
manufactures and distributes precision instruments to calibrate and test
electronic equipment and provides repair, upgrade and calibration services for
its products on a worldwide basis. The accompanying consolidated financial
statements include the operations of the Company and its wholly-owned
subsidiaries. All significant intercompany accounts and transactions have been
eliminated in consolidation.
 
    FOREIGN CURRENCY
 
    The accounts of foreign subsidiaries consolidated herein have been
translated from their respective functional currencies into U.S. dollars at
appropriate exchange rates. Cumulative translation adjustments are included as a
separate component of stockholders' equity. Exchange gains and losses from
foreign currency transactions are included in "Other, net" in the accompanying
consolidated statements of income.
 
   
    INTERIM FINANCIAL INFORMATION (UNAUDITED)
    
 
   
    The consolidated financial statements at June 30, 1997 and for the nine
month periods ended June 30, 1996 and 1997 are unaudited, but include all
adjustments (consisting of normal recurring adjustments) which management
considers necessary for a fair presentation of the financial position at such
date and the operating results and cash flows for those periods. Results for
interim periods are not necessarily indicative of results of the entire year or
any future periods.
    
 
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
    CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
    It is the Company's policy to invest excess funds in highly liquid,
short-term investments. Such investments are comprised primarily of U.S.
Treasury securities, guaranteed obligations of the U.S. government or its
agencies, mutual funds, which invest in U.S. Treasury securities, and money
market accounts and are stated at cost, which approximates market. For purposes
of financial statement presentation, the Company considers all highly liquid
investments with a maturity of three months or less at date of purchase to be
cash equivalents.
 
    INVENTORIES
 
    Inventories are valued at cost determined on the first-in, first-out basis,
not in excess of market.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
 (INFORMATION SUBSEQUENT TO SEPTEMBER 30, 1996 AND PERTAINING TO JUNE 30, 1997
 
     AND THE NINE-MONTH PERIODS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
 
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    PROPERTY AND EQUIPMENT
 
    Property and equipment are recorded at cost. Depreciation for financial
statement purposes is computed using the straight-line method based upon the
estimated useful lives of the various classes of assets which range from 3 to 35
years for buildings and improvements and from 3 to 10 years for fixtures and
equipment.
 
    DEFERRED DEBT ISSUANCE COSTS
 
    Costs associated with the issuance of long-term debt have been deferred and
are being amortized over the term of the related debt using the interest method.
Amortization expense for these costs is included in interest expense in the
accompanying consolidated statements of income.
 
    INTANGIBLE ASSETS
 
    Intangible assets consist of covenants not to compete and the excess of
purchase price over net tangible assets of businesses acquired (goodwill) and
are recorded at cost. Intangible assets are amortized over their estimated lives
ranging from five to fifteen years.
 
    IMPAIRMENT OF LONG-LIVED ASSETS
 
    Effective October 1, 1995, the Company adopted Statement of Financial
Accounting Standards No. 121, ACCOUNTING FOR THE IMPAIRMENT OF LONG-LIVED ASSETS
AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF ("SFAS 121"). SFAS 121 establishes
accounting standards for recording the impairment of long-lived assets,
including identifiable intangibles and goodwill. The adoption of SFAS 121 did
not have a material impact on the Company's financial position or the results of
its operations.
 
    REVENUE AND CREDIT RISK
 
    Sales are recognized at the time of shipment. The Company grants credit to
its customers based on an evaluation of the customers' financial condition, and
generally, collateral is not required. Credit losses have traditionally been
minimal and within management's expectations.
 
    NET INCOME PER SHARE
 
    Net income per share has been computed using the weighted average number of
common shares and dilutive common stock equivalents outstanding during the
periods presented. Common stock equivalents result from outstanding options to
purchase common stock.
 
    In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, EARNINGS PER SHARE ("SFAS 128"),
which is required to be initially adopted by the Company for its reporting
period ending December 31, 1997. At that time, the Company will be required to
change the method currently used to compute net income per share and to restate
all prior periods. Under the new requirements for calculating primary net income
per share, the dilutive effect of stock options will be excluded. The impact is
expected to result in no change to reported net income per share for the fiscal
year ended September 30, 1994, an increase in primary net income per share for
the fiscal

years ended September 30, 1995 and 1996 of $.01 and $.05 per share,
respectively, and the nine month periods ended June 30, 1996 and 1997 of $.05
and $.02 per share, respectively.
 
    STOCK-BASED COMPENSATION
 
    In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK-BASED
COMPENSATION ("SFAS 123"), which is effective for the year ending September 30,
1997. SFAS 123 allows companies to either account for stock-based compensation
under the new provisions of SFAS 123 or under the provisions of Accounting
Principles Board Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB
25"), but requires pro forma disclosure in the footnotes to the financial
statements as if the measurement provisions of SFAS 123 had been adopted. The
Company has continued accounting for its stock-based compensation in accordance
with the provisions of APB 25.
 
    FINANCIAL INSTRUMENTS
 
    The Company periodically uses forward exchange contracts to hedge certain
transactions denominated in foreign currencies. Unrealized gains and losses on
forward contracts are deferred and offset against foreign exchange gains or
losses on the underlying hedged item. At September 30, 1996 and June 30, 1997,
the Company had no material forward exchange contracts outstanding.
 
   
    RECENTLY ISSUED ACCOUNTING STANDARDS
    
 
   
    In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, REPORTING COMPREHENSIVE INCOME ("SFAS
130"), and Statement of Financial Accounting Standards No. 131, SEGMENT
INFORMATION ("SFAS 131"). Both of these standards are effective for fiscal years
beginning after December 15, 1997. SFAS No. 130 requires that all components of
comprehensive income, including net income, be reported in the financial
statements in the period in which they are recognized. Comprehensive income is
defined as the change in equity during a period from transactions and other
events and circumstances from non owner sources. Net income and other
comprehensive income, including foreign currency translation adjustment, minimum
pension accrual, and unrealized gains and losses on investments, shall be
reported, net of their related tax effect, to arrive at comprehensive income.
The Company intends to adopt SFAS 130 in fiscal 1999 and operating results of
prior periods will be reclassified. The Company's only component of other
comprehensive income is the foreign currency translation adjustment which is
currently reported as part of stockholders' equity. Historically, the Company
has operated in one business segment; however, SFAS 131 redefines segments and
in the future, the Company will be required to disclose certain financial
information about operating segments, products, services and geographic areas in
which they operate. The Company has not determined how operating segments will
be defined for disclosure purposes or which segments will meet the quantitative
requirements for disclosure. The adoption of the standard will have no impact on
the Company's future results of operations or financial position.

3. RECAPITALIZATION TRANSACTIONS
 
    On June 11, 1997, the Company completed the following transactions (the
Recapitalization Transactions): (i) the Company sold an aggregate of 2,428,470
shares of its Common Stock, representing 49.7% of the Common Stock outstanding
following the Recapitalization Transactions, to DLJ Merchant Banking Partners
II, L.P. and its affiliates and Green Equity Investors II, L.P. and its
affiliates for an aggregate purchase price of $43.5 million, less related costs
of $644,000 (the New Equity Investment); (ii) the Company issued $85 million
aggregate principal amount of 10 1/8% Senior Subordinated Notes maturing June
15, 2007 (the Notes) (Note 6); (iii) the Company incurred indebtedness of $25
million under a five year and six month term loan facility and entered into a
five year and six month revolving credit facility providing for borrowings of up
to $20 million (the New Credit Agreement) (Note 6); (iv) the Company incurred
aggregate debt issuance costs of $4.3 million in connection with the issuance of
the Notes and with entering the New Credit Agreement; (v) the Company used the
net proceeds from the New Equity Investment, the issuance of the Notes and the
New Credit Agreement to repurchase an aggregate of 8,513,610 shares of Common
Stock from existing stockholders for an aggregate of $152.5 million and to make
cash payments upon surrender of stock options by employees in an aggregate
amount of $7.1 million (Note 9). Such existing stockholders retained 50.3% of
the shares of Common Stock outstanding following the Recapitalization
Transactions.
 
4. STRATEGIC ALLIANCE AND PURCHASE AND SALE OF BUSINESS
 
    In April 1996, the Company entered into a Strategic Alliance with Yokogawa
Electric Corporation (Yokogawa), a leading Japanese process control and test and
measurement company. Under terms of the Strategic Alliance, Yokogawa acquired
all of the outstanding shares of the Company's Japanese subsidiary for 10
million Japanese Yen (approximately $93,000) and 12% of the Company's Common
Stock from certain of the Company's stockholders. There was no significant gain
or loss on the sale of the Japanese subsidiary. Additionally, Yokogawa will
distribute the Company's products in Japan and Yokogawa and the Company will
collaborate to develop new products for the communications test markets
worldwide. In connection with the June 1997 Recapitalization Transactions (Note
3), the Company repurchased a portion of the Common Stock owned by Yokogawa,
reducing Yokogawa's ownership of the outstanding Common Stock to 5.8%.
 
    In October 1995, the Company sold its Industrial Measurement Instruments
(IMI) product line to a third party for $502,000, resulting in a gain of
$56,000. The Company received $310,000 cash on the closing date. The remaining
proceeds were being paid under the terms of two promissory notes which were
fully repaid in June 1997 ($150,000 was outstanding at September 30, 1996).
Under the terms of the sale agreement, the Company is entitled to receive
royalties from the buyer based on its sales of IMI products for four years
following the closing date. The Company received royalties aggregating $92,000
in fiscal 1996, and $57,000 and $69,000 in the nine months ended June 30, 1996
and 1997, respectively.
 
    In October 1994, the Company acquired certain worldwide assets and
liabilities of the communications test division of Schlumberger for
approximately $16.1 million (the "Schlumberger Acquisition"). Of the total
purchase price, $13.0 million was paid in cash on the closing date and an
additional $2.1 million was paid in cash in April 1995. The remaining balance of
5,167,000 French francs (approximately $900,000 at June 30, 1997) will be paid
under terms of a promissory note due in January 1998 (Note 6). The acquisition
was accounted for as a purchase and the assets and liabilities of the acquired
business were

recorded at their estimated fair values, including goodwill of $4.2 million.
Additionally, $4.2 million was accrued as an estimate of the costs that would be
incurred to restructure and integrate the acquired business into the Company, of
which $3.4 million had been spent as of September 30, 1996 and June 30, 1997 and
$754,000 was included in other current liabilities in the accompanying balance
sheet at September 30, 1996 ($739,000 as of June 30, 1997). In connection with
this transaction, Schlumberger purchased 57,600 shares of the Company's Common
Stock for $3.0 million in cash. The Company repurchased these shares in
September 1995 for $3.2 million in cash.
 
5. SALE AND LEASEBACK FINANCING
 
    To raise funds for the Schlumberger Acquisition, in October 1994, the
Company entered into a sale and leaseback financing whereby it sold its facility
in Indianapolis to a third party investor for $4.5 million, resulting in a
charge to income of $1.8 million, representing the excess of the net book value
of the property over the net proceeds received. The Company simultaneously
entered a Master Lease Agreement with the buyer, under which the Company leased
back the facility for a period of 20 years for an annual rental $473,000,
subject to annual adjustments based on the change in the consumer price index,
not to exceed 3.0% per annum. In December 1994, the Company subleased a portion
of this facility to a third party for five years for an annual base rental and
common area expense reimbursement of $387,000. Because of the significance of
the sublease in relation to the Company's master lease of the facility,
generally accepted accounting principles require that the transaction be
recorded as a financing transaction, whereby the building remains on the
Company's balance sheet in an amount equal to the net proceeds from the sale and
an offsetting long-term financing obligation has been recorded.

6. CREDIT AGREEMENTS AND LONG-TERM OBLIGATIONS
 
    The Company's U.S. subsidiary had a Business Loan Agreement (Agreement) with
a bank providing for revolving line of credit borrowings of up to $4.0 million.
This Agreement was terminated in June 1997. The Company had no borrowings under
this agreement as of September 30, 1996.
 
    The Company's subsidiaries in the United Kingdom, France, Germany and
Austria also have agreements with banks providing for short-term revolving
advances and overdraft facilities in an aggregate total amount of approximately
$6.5 million. In addition, the bank agreements with such subsidiaries also
provide for issuance of letters of credit and bank guarantees in an aggregate
total amount of approximately $4.0 million. At September 30, 1996 and June 30,
1997, aggregate amounts of $786,000 and $3.4 million, respectively, had been
borrowed under these facilities. Revolving borrowings under these agreements
bear interest at variable rates ranging from 4.863% to 8.25% as of September 30,
1996 (4.20% to 8.40% as of June 30, 1997). These bank agreements also provide
for long-term borrowings (see table below) and are generally secured by the
assets of the local subsidiary and the guarantee of the Company. Most of these
agreements do not have stated expiration dates, but are cancellable by the banks
at any time. The Company's bank agreements also generally provide for the
issuance of letters of credit and bank guarantees. At September 30, 1996 and
June 30, 1997, the Company was contingently liable for outstanding letters of
credit and bank guarantees aggregating $1.3 million and $2.1 million,
respectively. Borrowings under the Company's revolving bank agreements have been
classified as "Notes payable to banks" in the accompanying consolidated balance
sheets due to the short-term nature of the revolving advances taken under these
agreements.
 
    Long-term obligations are as follows:

</TABLE>
 
    As of September 30, 1996, the future annual principal payments on long-term
obligations outstanding at September 30, 1996 were as follows for fiscal years
ending September 30: 1997 -- $95,000; 1998 -- $1,106,000; 1999 -- $112,000; 2000
- -- $123,000; 2001 -- $135,000 and thereafter -- $3,597,000.
 
    In connection with the Recapitalization Transactions (Note 3), the Company
issued $85 million aggregate principal amount of Senior Subordinated Notes
(Notes) pursuant to an Indenture (the Indenture) between the Company and the
Bank of New York, as trustee. The Notes bear interest at 10.125%, payable
semi-annually on each June 15 and December 15 commencing December 15, 1997. The
total principal balance of the Notes is due June 15, 2007. On or after June 15,
2002, the Notes will be redeemable at the option of the Company, in whole or in
part, at the following redemption prices (expressed as percentages of principal
amount) plus accrued and unpaid interest and liquidated damages, if any:
105.063% if redeemed during the twelve-month period beginning on June 15, 2002;
103.375% if redeemed during the twelve-month period beginning on June 15, 2003;
101.688% if redeemed during the twelve-month period beginning on June 15, 2004;
and 100% thereafter. Notwithstanding the foregoing, during the first three years
following the issue date of the Notes, the Company may redeem up to 33 1/3% of
the aggregate principal amount of the Notes with the proceeds of one or more
Public Equity Offerings (as defined in the Indenture) at a redemption price of
110.125% of the principal amount thereof, in each case plus accrued and unpaid
interest and liquidated damages, if any. The Notes are guaranteed on a senior
subordinated basis by the Company's current and future subsidiaries in the
United States. The Indenture requires the Company to comply with various
affirmative, negative, and financial covenants. The Company was in compliance
with all such covenants at June 30, 1997.
 
    Also in connection with the Recapitalization Transactions, the Company
entered into a New Credit Agreement (New Credit Agreement) with a group of five
lending banks (the Lenders) including DLJ Capital Funding, Inc. as Syndication
Agent and Fleet National Bank as Administrative Agent. The New Credit Agreement
provided for a $25 million five year and six month term loan (Term Loan)
borrowed by the Company on June 11, 1997. The Term Loan is repayable in
quarterly installments on the 15th day of each September, December, March and
June commencing September 15, 1998. Total principal payments due in each future
fiscal year are as follows: 1998--$1,000,000; 1999--$4,250,000;
2000--$5,250,000;

2001--$6,250,000; 2002--$6,750,000 and; 2003--$1,500,000. The Term Loan may be
prepaid at any time and is subject to mandatory prepayments if the Company
generates Excess Cash Flow (as defined in the New Credit Agreement). The New
Credit Agreement also provides for a five year and six month revolving credit
facility in the amount of $20 million, of which up to $7.5 million may be
borrowed in British pounds, French francs or Deutsche marks. The Company has no
borrowings outstanding under the revolving credit facility. All borrowings under
the New Credit Agreement bear interest, at the option of the Company, at either
(i) the Base Rate (as defined in the New Credit Agreement) plus 1.5%, or (ii) at
the reserve adjusted Euro-Dollar Rate (as defined in the New Credit Agreement)
plus 2.50%, subject to reduction upon the achievement of certain performance
levels and/or credit ratios. The Term Loan currently bears interest at 8.1875%
through August 14, 1997, with interest payable at the end of each one-month
period. The New Credit Agreement is secured by all of the Company's assets in
the United States (approximately $52.5 million at June 30, 1997) and the pledge
of 100% of the stock of its subsidiaries in the United States and 65% of the
stock of its foreign subsidiaries. The New Credit Agreement requires the Company
to comply with various affirmative, negative, and financial covenants. The
Company was in compliance with all such covenants at June 30, 1997.
 
    The Company incurred aggregate debt issuance costs of $4.3 million in
connection with the issuance of the Notes and with entering into the New Credit
Agreement. Such costs have been deferred and will be amortized over the term of
the related debt using the interest method.
 
7. EMPLOYEE RETIREMENT SAVINGS PLAN
 
    The Company has a tax deferred retirement savings plan under Section 401(k)
of the Internal Revenue Code whereby U.S. employees may defer a portion of their
compensation through payroll deductions as contributions to the Plan. The
Company may match a portion of the savings contribution as prescribed in the
Plan. The Company's contributions may be made each year out of accumulated
profits in cash, and are at the discretion of the Board of Directors.
Contributions by the Company to the Plan were $211,000, $221,000 and $215,000
for the years ended September 30, 1994, 1995 and 1996, respectively, and
$170,000 and $213,000 for the nine months ended June 30, 1996 and 1997,
respectively.
 
8. LEASE COMMITMENTS
 
    The Company rents certain office and plant facilities under operating leases
which expire at various dates through 2006, except for a land lease in the U.K.
extending to 2103. The leases generally provide that the Company pay the taxes,
insurance and maintenance expenses related to the leased property. Certain
leases include renewal options and/or options to purchase the leased property.
The Company also rents equipment and other facilities on a month-to-month basis.
Total rent expense was $1.2 million, $2.6 million and $2.6 million for the years
ended September 30, 1994, 1995 and 1996, respectively, and $2.0 million for each
of the nine month periods ended June 30, 1996 and 1997, respectively.
 
    In 1991, the Company entered into a sale/leaseback arrangement for its San
Diego manufacturing facility with an affiliate of a major stockholder. The lease
runs through June 2006 with the minimum annual rental of $570,000, subject to
annual CPI adjustments. The Company's gain on the transaction was deferred and
is being amortized over the original ten-year lease term.

9. STOCKHOLDERS' EQUITY
 
    Prior to June 11, 1997, the Company had two classes of Common Stock
outstanding, Common Stock and Class B Common Stock. The rights and preferences
of both classes of common stock were identical, except that holders of Common
Stock were entitled to one vote per share and holders of Class B Common Stock
were entitled to ten votes per share. The Class B Common Stock was convertible,
at the holder's option, into shares of Common Stock on a share for share basis.
Total common stock authorized and issued and outstanding in each period
presented in the accompanying consolidated financial statements included two
million shares of Class B Common Stock through June 11, 1997. In connection with
the Recapitalization Transactions (Note 3), all shares of Class B Common Stock
were repurchased by the Company and the Company's Certificate of Incorporation
was amended to eliminate the Class B Common Stock. The Company's Certificate of
Incorporation was also amended effective June 11, 1997 to effect a ten-for-one
stock split of its common stock, which was authorized by the Company's Board of
Directors on May 30, 1997. All share and per share amounts and stock option data
in the accompanying consolidated financial statements have been restated to
retroactively reflect the stock split.
 
    In connection with Yokogawa's purchase of shares of the Company's Common
Stock (Note 4), the Company and its stockholders entered certain agreements with
Yokogawa which provided Yokogawa with certain rights of first refusal through
April 1999 if shares of the Company's Common Stock were offered for sale in
certain circumstances defined by the agreements. Yokogawa was also granted the
right to appoint one member to the Company's Board of Directors. In connection
with the Recapitalization Transactions (Note 3), all such preferential rights of
Yokogawa were terminated effective June 11, 1997.
 
    In accordance with the Company's 1992 Nonqualified Stock Option Plan,
options to purchase an aggregate of up to one million shares of Common Stock may
be issued to employees at an exercise price equal to the fair value of the
shares on the date of grant. At September 30, 1994, 1995, 1996 and at June 30,
1997, options to purchase 560,000, 786,000, 843,000 and 322,400 common shares,
respectively, had been granted and were outstanding at exercise prices ranging
from $1.25 to $12.50 per share. Options to purchase an aggregate of 116,000
shares were exercisable at September 30, 1996 at an exercise price of $1.25 per
share and 139,150 shares were exercisable at June 30, 1997 at exercise prices
ranging from $1.25 to $12.50 per share. All options expire on the earlier of
April 28, 2002, or 90 days after termination of

employment. Prior to the Recapitilization Transactions (Note 3), options to
purchase 805,000 common shares had been issued and were outstanding. In
connection with the Recapitalization Transactions, the Company accelerated the
vesting of these outstanding options such that 75% of each option holders'
options became fully vested and the Company offered to make cash payments to
each option holder as compensation for the surrender of all or a portion of such
vested options in a per share amount equal to the price paid to the selling
stockholders in the Recapitalization Transactions. Such surrendering option
holders were also required to pay a pro rata portion of the expenses incurred by
the selling stockholders. Holders of vested options to purchase 472,100 common
shares elected to surrender such options in exchange for payments aggregating
approximately $6.8 million. The amount of such payments, and related employer
expenses of $237,000, were recorded as compensation expense in the accompanying
consolidated statement of income for the nine months ended June 30, 1997.
 
10. PROVISIONS FOR RESTRUCTURED OPERATIONS
 
    In fiscal year 1996, the Company initiated a plan to restructure certain
corporate management functions, its European manufacturing, service and sales
activities and its San Diego manufacturing activities. The restructuring costs
primarily include expenses for employee severance and close down of certain
manufacturing operations. The restructuring plan is expected to be completed
during fiscal 1997. A provision for the restructuring of $1.8 million is
included in the accompanying consolidated statement of income for fiscal 1996
($188,000 for the nine months ended June 30, 1996).

13. SUPPLEMENTAL CONDENSED CONSOLIDATING FINANCIAL DATA
 
    The Company's payment obligations under the Notes to be issued in the
Recapitalization Transactions are guaranteed by all of the Company's current and
future domestic subsidiaries (collectively, the "Subsidiary Guarantors"). Such
guarantees are full, unconditional and joint and several. Separate financial
statements of each of the Subsidiary Guarantors are not presented because the
Company's management has deemed that they would not be material to investors.
The following supplemental condensed consolidating financial data sets forth, on
an unconsolidated basis, balance sheets, statements of income and statements of
cash flows data for (i) the Company ("Wavetek Corporation"), (ii) the current
Subsidiary Guarantors and (iii) the Company's current foreign subsidiaries (the
"Foreign Subsidiaries"). The supplemental financial data reflects the
investments of Wavetek Corporation in the Subsidiary Guarantors and the Foreign
Subsidiaries using the equity method of accounting. Certain reclassifications
have been made to provide for uniform disclosure of all periods presented. The
reclassifications are not material.

                   10 1/8% SENIOR SUBORDINATED NOTES DUE 2007
 
    The 10 1/8% Senior Subordinated Notes due 2007 (the "New Notes" or the
"Notes") mature on June 15, 2007. Interest on the Notes will be payable
semi-annually on June 15 and December 15 of each year, commencing on December
15, 1997. The Notes will be redeemable at the option of the Company, in whole or
in part, at any time on or after June 15, 2002, at the redemption prices set
forth herein, plus accrued and unpaid interest and Liquidated Damages (as
defined), if any, to the date of redemption. However, during the first three
years after the Issue Date (as defined), the Company may redeem up to an
aggregate of 33 1/3% of the aggregate principal amount of Notes originally
issued in the Offering with the proceeds of one or more Public Equity Offerings
(as defined) at a redemption price of 110.125% of the principal amount thereof,
in each case plus accrued and unpaid interest and Liquidated Damages, if any, to
the redemption date; PROVIDED, HOWEVER, that at least 66 2/3% of the aggregate
principal amount of Notes originally issued remains outstanding immediately
after such redemption. Upon the occurrence of a Change of Control (as defined),
holders of the Notes will have the right to require the Company to purchase all
or any part of their Notes at a price equal to 101% of the aggregate principal
amount thereof, plus accrued and unpaid interest and Liquidated Damages, if any,
to the date of purchase. See "Description of Notes."
 
   
    The Notes are subordinated in right of payment to all existing and future
Senior Debt (as defined) of the Company, including borrowings under the New
Credit Agreement (as defined). The Notes are jointly and severally guaranteed on
a full and unconditional senior subordinated basis (the "Subsidiary Guarantees")
by the Subsidiary Guarantors (as defined). As of the date of this Prospectus,
Wavetek U.S., Inc. is the only Subsidiary Guarantor. The Subsidiary Guarantees
are subordinated in right of payment to all existing and future Senior Debt of
the Subsidiary Guarantors, including guarantees of the New Credit Agreement. The
Notes, the Subsidiary Guarantees and borrowings under the New Credit Agreement
are effectively subordinated to the indebtedness of the Company's foreign
subsidiaries (as defined). The Indenture permits the Company and its
Subsidiaries to incur additional Indebtedness, including Senior Debt, subject to
certain limitations, and prohibits the incurrence of any Indebtedness by the
Company and the Subsidiary Guarantors that is senior to the Notes or the
Subsidiary Guarantees, as the case may be, and subordinated to Senior Debt of
the Company or Senior Debt of the Subsidiary Guarantors, as the case may be. See
"Description of Notes." At June 30, 1997, the Company had approximately $114.1
million of outstanding debt and stockholders' deficit of $73.0 million. As of
June 30, 1997, the Company and its subsidiaries had approximately $29.3 million
of outstanding debt that effectively ranks senior to the Notes and the
Subsidiary Guarantees. Additional senior debt may be incurred by the Company and
its subsidiaries from time to time, subject to certain restrictions.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The Delaware General Corporation Law (the "DGCL") authorizes corporations to
limit or eliminate the personal liability of directors to the corporation and
its stockholders for monetary damages in connection with the breach of a
director's fiduciary duty of care. The duty of care requires that, when acting
on behalf of the corporation, directors must exercise an informed business
judgment based on all material information reasonably available to them. Absent
the limitation authorized by the DGCL, directors could be accountable to
corporations and their stockholders for monetary damages for conduct that does
not satisfy such duty of care. Although the DGCL does not change a director's
duty of care, it enables corporations to limit available relief to equitable
remedies such as injunction or rescission.
 
    The Company's Certificate of Incorporation contains a provision permitted
under the Delaware General Corporation Law (the "DGCL") eliminating each
director's personal liability for monetary damages for breach of fiduciary duty
as a director, except to the extent that such exemption from liability or
limitation thereof is not permitted under the DGCL as currently in effect at the
time. The Company's Bylaws authorize the Company to indemnify its present and
former directors, officers and employees against expenses, judgments, fines and
amounts paid in settlement if such person is made a party, or is threatened to
be made a party, to a legal proceeding by reason of the fact that such person is
or was a director, officer, employee or agent of the Company, or was serving in
such position at another company at the request of the Company. Such
indemnification is mandatory in certain circumstances and permissive in others,
subject to authorization by the Company's Board of Directors. In addition, the
Bylaws authorize the Company to advance litigation expenses to such person prior
to the final disposition of the legal proceeding.

ITEM 22. UNDERTAKING.
 
    Each of the undersigned Registrants hereby undertakes:
 
        (a)(1)  To file, during any period in which offers or sales are being
    made, a post-effective amendment to this Registration Statement:
 
           (i) To include any prospectus required by Section 10(a)(3) of the
       Securities Act of 1933.
 
                                      II-2
<PAGE>
   
           (ii) To reflect in the prospectus any facts or events arising after
       the effective date of the Registration Statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the Registration Statement. Notwithstanding the foregoing, any increase
       or decrease in volume of securities offered (if the total dollar value of
       securities offered would not exceed that which was registered) and any
       deviation from the low or high and of the estimated maximum offering
       range may be relected in the form of prospectus filed with the Commission
       pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
       price represent no more than 20 percent change in the maximum aggregate
       offering price set forth in the "Calculation of Registration Fee" table
       in the effective registration statement.
    
 
           (iii) To include any material information with respect to the plan of
       distribution not previously disclosed in the Registration Statement or
       any material change to such information in the Registration Statement.
 
        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment shall be deemed
    to be a new registration statement relating to the securities offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
        (b) That, for purposes of determining any liability under the Securities
    Act of 1933, each filing of the Registrant's annual report pursuant to
    Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
    applicable, each filing of an employee benefit plan's annual report pursuant
    to Section 15(d) of the Securities Exchange Act of 1934) that is
    incorporated by reference in the Registration Statement shall be deemed to
    be a new registration statement relating to the securities offered therein,
    and the offering of such securities at that time shall be deemed to be the
    initial BONA FIDE offering thereof.
 
        (c) To respond to requests for information that is incorporated by
    reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
    Form, within one business day of receipt of such request, and to send the
    incorporated documents by first class mail or other equally prompt means.
    This includes information contained in documents filed subsequent to the
    effective date of the Registration Statement through the date of responding
    to the request.
 
        (d) To supply by means of a post-effective amendment all information
    concerning a transaction, and the company being acquired involved therein,
    that was not the subject of and included in the Registration Statement when
    it became effective.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions referred to in Item 20, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction, the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
