Test Equipment Required - Tektronix 442 Service Manual

Section 4—442 Service
CALIBRATION PROCEDURE
Introduction
This section of the manual is in two parts: Performance
Check and Adjustment Procedure. Each subsection has a
different purpose and important information regarding
their use is included at the beginning of both subsections.
The test equipment listed in Table 4-1, or an equivalent
piece of test equipment, is required if the complete
Performance Check and Adjustment Procedure is to be
