EXHIBIT 31.1

                                  CERTIFICATION

I, Thomas H. Reslewic, Chief Executive Officer, certify that:

1.  I have reviewed this quarterly report on Form 10-Q of LeCroy
    Corporation;

2.  Based on my knowledge, this report does not contain any untrue
    statement of a material fact or omit to state a material fact
    necessary to make the statements made, in light of the
    circumstances under which such statements were made, not
    misleading with respect to the period covered by this report;

3.  Based on my knowledge, the financial statements, and other
    financial information included in this report, fairly present in
    all material respects the financial condition, results of
    operations and cash flows of the registrant as of, and for, the
    periods presented in this report;

4.  The registrant's other certifying officer and I are responsible
    for establishing and maintaining disclosure controls and
    procedures (as defined in Exchange Act Rules 13a-15(e) and
    15d-15(e)) for the registrant and we have:

    a.  Designed such disclosure controls and procedures, or caused such
        disclosure controls and procedures to be designed under our supervision,
        to ensure that material information relating to the registrant,
        including its consolidated subsidiaries, is made known to us by others
        within those entities, particularly during the period in which this
        report is being prepared;

    b.  Evaluated the effectiveness of the registrant's disclosure controls and
        procedures and presented in this report our conclusions about the
        effectiveness of the disclosure controls and procedures, as of the end
        of the period covered by this report based on such evaluation; and

    c.  Disclosed in this report any change in the registrant's internal control
        over financial reporting that occurred during the registrant's most
        recent fiscal quarter (the registrant's fourth fiscal quarter in the
        case of an annual report) that has materially affected, or is reasonably
        likely to materially affect, the registrant's internal control over
        financial reporting; and

5.  The registrant's other certifying officer and I have disclosed,
    based on our most recent evaluation of internal control over
    financial reporting, to the registrant's auditors and the audit
    committee of the registrant's board of directors (or persons
    performing the equivalent functions):

    a.  All significant deficiencies and material weaknesses in the design or
        operation of internal control over financial reporting which are
        reasonably likely to adversely affect the registrant's ability to
        record, process, summarize and report financial information; and

    b.  Any fraud, whether or not material, that involves management or other
        employees who have a significant role in the registrant's internal
        control over financial reporting.
