Test Procedures
Refer to Figure 4--11 on page 4--28 for component and test point locations used
in the following procedures. Table 4--6 on page 4--28 describes the functions of
the jumpers used on the fixture for verifying the performance of the Tektronix
logic analyzers. The jumpers are also used in these procedures.
All procedures must be followed sequentially. If any single step fails or is out of
calibration, then upon retest, you must start at the first test and follow this
section through from start to finish sequentially.
The following procedures check the DC power supply characteristics.
Parameter tested Power supply

Prerequisites Warm-up time: 30 minutes for adjustment/verification fixture and test
equipment
1.
Plug the fixture supply into an appropriate AC outlet and connect the
DC plug to J26 on the adjustment/verification fixture.
2. Connect the DMM (--) lead to J8 (V
