Performance Tests
Introduction
2-4 Agilent E4418B/E4419B Service Guide
Performance Test Record
Results of the performance tests may be tabulated in Table 2-8,
“Performance Test Record,” on page 2-30. The Performance Test Record
lists all of the performance test specifications and the acceptable limits for
each specification. If performance test results are recorded during an
incoming inspection of the power meter, they can be used for comparison
during periodic maintenance. The test results may also prove useful in
verifying proper adjustments after repairs are made.
Performance Tests
The performance tests given in this chapter are suitable for incoming
inspection or preventive maintenance. During any performance test, all
shields and connecting hardware must be in place.
The tests are designed to verify published power meter specifications.
Perform the tests in the order given and record the data in Table 2-8 on
page 2-30 and/or in the data spaces provided at the end of each procedure.
Calibration Cycle
This power meter requires periodic verification of performance to ensure
that it is operating within specified tolerances. The performance tests
described in this chapter should be performed once every two years. Under
conditions of heavy usage or severe operating environments, the tests
should be more frequent. Adjustments that may be required are described
in Chapter 3.
Test Procedures
It is assumed that the person performing the following 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.
