Keysight N1914A - Performance Tests; Introduction

2 Performance Tests
48 Keysight N1913/1914A 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, during 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” on page 51
– “Output Standing Wave Ratio (SWR) Test” on page 53
– “Zero Set (Average Path)” on page 56
– “Absolute Accuracy Test (Average Path)” on page 57
– “Linearity (Average Path)” on page 61
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 N7800 Series 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 N7800 Series
calibration software is essential.
– Measurement uncertainty will not be addressed in this document (this is
handled by the N7800 Series software).
