Testing and Calibration
5.1 General
This chapter is a procedural guideline for performance evaluation and calibration of the 8501A and
8502A Peak Power Meters (PPM) and power detectors. These tests can also be used for performance
testing when the instrument is first received.
The Information in this chapter can be used to calibrate and/or confirm calibration of the PPM and its
detectors, using the built-in automatic detector calibration system.
The performance tests are valid only if the detector has been automatically calibrated at an ambient
temperature between 15 and 35 °C (59 and 95 °F), and is operating within ±5 °C (±9 °F) of this
temperature at the time of calibration.
If the PPM has not been previously used, you should review Chapter 2 of this manual to ensure that
power requirements and detector precautions have been complied with before the instrument is turned on.
The instrument has been factory-calibrated and should not be re-calibrated before the performance tests
detailed in this chapter have been completed. Before starting the performance test procedures, the
instrument should be warmed up for at least 30 minutes for maximum stability during testing.
Performance test data and calibration recording sheets are located at the end of this chapter. These sheets
can be copied and used for recording the results each time performance tests and calibration are
performed on the instrument.
