For Immediate Release


             DYNATECH CEO AND NOMINATING COMMITTEE HEAD COMMIT TO
                   ACCELERATE BOARD REVITALIZATION PROCESS


BURLINGTON, MASSACHUSETTS, July 25, 1994 . . . John F. Reno, president and CEO
of Dynatech Corporation (Nasdaq: DYTC), and Richard K. Lochridge, chairman of
the nominating committee of Dynatech, stated today that a number of major
institutional shareholders have recently asked the Company to accelerate the
process of revitalizing its Board, and Messrs. Reno and Lochridge have
committed to do so.

Messrs. Reno and Lochridge also said: "With successful resolution of tomorrow's
contested Annual Meeting, we have pledged to seek significant changes in the
Board structure in the near term. We are convinced that, without the divisive
element on our Board, we will be able to complete the process of revitalizing
the Board with highly qualified candidates."

At Dynatech's Annual Meeting at 10:00 a.m. on Tuesday, July 26, shareholders
will vote on the election of three directors, a new stock option plan, and a
proposal by SC Fundamental, a dissident Dynatech shareholder.

Mr. Reno added: "We strongly urge all shareholders to support the Board's
efforts to enhance value through out existing restructuring program. We are
asking all shareholders to vote for management's proposals and against SC
Fundamental's proposal."

The Dynatech Board in fiscal 1994 appointed a nominating committee and hired a
nationally recognized search firm to assist it in implementing Board changes.
Mr. O. Gene Gabbard, previously Executive Vice President and Chief Financial
Officer of MCI Communications Corporation, was recently brought onto the Board
as part of that process, and a number of other qualified candidates are under
active consideration as successors for several current directors.

With fiscal 1994 sales of $458 million from continuing operations, Dynatech
Corporation supplies products for the support of voice, video, and data
communications. Headquartered in Burlington, Massachusetts, Dynatech sells its
products worldwide through subsidiaries located throughout North America,
Europe and Asia.
