2Performance Tests
20 N1911A/1912A P-Series 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:
• 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).
