2 Performance Tests
42 Keysight N8262A 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:
– 1 mW Power Reference Level Test
– Output Standing Wave Ratio (SWR) Test (Power Reference Output)
– Time Base Frequency Accuracy
– Zero Set (Average Path)
– Zero Set (Peak Path)
– Linearity (Average Path)
– Absolute Accuracy Test (Average Path)
– Rise/Fall Time (Peak Path)
– This document does not provide a complete breakdown for these tests; it only
gives a brief overview of each, in line with Keysight’s recommendation that
the Keysight N7832A calibration software should be used at all times.
– Performance Testing is limited to the measurement and verification of
warranted specifications.
– Some tests cannot be performed manually, and so the N7832A calibration
software is essential.
– Measurement uncertainty will not be addressed in this document (this is
handled by the N7832A software).
