Performance Test Record
Performance test results can be recorded in Table 2-9, “Performance Test Record”
on page 68. The Performance Test Record table lists the performance test
specifications and the acceptable limits for each specification.
Calibration Cycle
Keysight E4416A and E4417A power meters require performance tests to be run
every two years to verify that they are operating within specified tolerances. Under
conditions of heavy usage or severe operating environments, this calibration cycle
should be performed more frequently.
Test Procedures
It is assumed that the person performing the tests understands how to operate
the specified test equipment. Equipment settings, other than those for the power
meter, are stated in general terms. It is assumed that the person will select the
proper cables, adapters, and probes required for test setups illustrated in this
chapter.
