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)
NOTE
– 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).
