ITEM 1.   SECURITY AND ISSUER

          This Schedule 13D relates to 388,658 shares of common stock (the
"Securities") of Cerprobe Corporation (the "Issuer") that are issuable upon
conversion of Series A Preferred Stock.  The principal executive offices of 
the Issuer are located at 600 South Rockford Drive, Tempe, Arizona  85281.

ITEM 2.   IDENTITY AND BACKGROUND

          This Schedule 13D is being filed by Citadel Limited Partnership, an
Illinois limited partnership ("Citadel").  Citadel's principal business office
is located at 225 West Washington Street, 9th Floor, Chicago, Illinois 60606.

ITEM 3.   SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

          Citadel is the trading manager for Olympus Securities, Ltd., a Bermuda
corporation ("Olympus") and is the managing general partner of Nelson Partners,
a Bermuda exempted general partnership ("Nelson"). The funds used for purchases
reported herein are from the accounts of Olympus and Nelson. Citadel has no
beneficial ownership interest in any of the funds or other property of Olympus
or Nelson, except for Citadel's interest as general partner of Nelson.

ITEM 4.   PURPOSE OF TRANSACTION

          The purchases reported herein were made as an investment. Citadel may,
in the future, recommend or make additional purchases or sales of the subject
Securities on behalf of Olympus or Nelson.

          Citadel has no present plans or proposals which would relate to or
result in transactions of the kind described in paragraphs (a) through (j) of
Item 4 of Rule 13D-101 of the Securities and Exchange Commission. However,
Citadel reserves the right to adopt such plans or proposals, subject to
applicable regulatory requirements, if any.

ITEM 5.   INTEREST IN SECURITIES OF THE ISSUER

          (a)  By reason of its serving as trading manager for Olympus and
               managing general partner of Nelson, Citadel may be deemed to be
               the indirect beneficial owner of the Securities, which represent
               a 7.88% interest in the common stock of the Issuer.

          (b)  Citadel has the sole power to vote and the sole power to dispose
               of the Securities on behalf of Olympus and Nelson.

          (c)  This filing is being made as a consequence of Citadel's
               deregistration as of September 27, 1996 as a registered
               investment advisor. Citadel, which changed its name from Citadel
               Investment Management, L.P. in connection with the
               deregistration, may have previously filed a Schedule 13G with
               respect to its investment in the Issuer under such former name.
               No transactions with respect to the Issuer's common stock have
               been effected during the 60-day period ending September 26, 1996.

          (d)  Citadel acquired the Securities as agent for Olympus and Nelson.
               Olympus and Nelson, as the direct beneficial and legal owners of
               the Securities, have the right to receive or the power to direct
               the receipt of dividends from, or the proceeds from the sale of
               the Securities. However, Citadel, as trading manager for Olympus
               and managing general partner of Nelson, ultimately has the right
               to direct such activities.

ITEM 6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
          TO SECURITIES OF THE COMPANY.

          Olympus and Nelson own 48.48% and 51.52% of the Securities,
          respectively. Olympus and Nelson have the right to receive any
          dividends from and the proceeds from the sale of the Securities. As
          described in Item 3 above, Citadel is the trading manager for Olympus
          and the managing general partner of Nelson. As a result, Citadel has
          the power to vote and dispose of the securities held by Olympus and
          Nelson.
