2 Performance Tests
26 Keysight E4416A/E4417A Power Meters Service Guide
Introduction
The performance tests described in this chapter test the power meter's electrical
performance against the specifications detailed in chapter 1. They are used for
incoming inspection, the calibration cycle (also called periodic maintenance), or
after repairs have been made.
The following performance tests are described in this chapter:
– Instrument accuracy (normal path) test.
– Instrument accuracy (average path) test.
– Power reference level test.
– Keysight E-Series power sensor interface test.
– Keysight E932x power sensor (average path) functional test.
– Time base accuracy test.
– Output standing wave ratio (SWR) test.
Equipment Required
Each performance test description details the equipment required by the test. In
addition, Appendix B summarizes the equipment required for all performance
tests and adjustments.
The following conditions must be met for valid performance tests:
– The power meter and test equipment must have a 30 minute warm-up for all
specifications.
– The line voltage for the power meter must be 85 to 264 Vac and the line
frequency must be 50 to 440 Hz.
– The ambient temperature must be 0
ºC to 55 ºC.
