Series 8500A Peak Power Meters
5.2 Performance Testing
The tests in this section are to determine that the performance of the Model 8501A or 8502A Peak Power
Meters (PPM) is within the parameters of the specifications given for the instrument. Assemble all of the
required test equipment and the PPM to be tested. Connect all equipment to the ac power line, turn it on,
and allow at least 30 minutes for it to warm up before starting the test.
5.2.1 Equipment Required
The equipment listed in Table 5-1 is required for Performance Testing. Equivalent or similar test
equipment can be substituted.
