Part I Performance Check; Outline For Part I Performance Check - Tektronix 7B92A Maintenance Manual

The following procedure is intended to be used for inspection and periodic calibration checks to confirm that the
7B92A is operating within acceptable limits. This procedure is concerned with those portions of the instrument calibration
that are essential to measurement accuracy and correct operation. Removal of the side covers is not necessary to
perform this procedure in that all checks are made from the front panel.
