Keysight N1911A/1912A 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)
–
Linearity (Peak 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).
