INTRODUCTION AND DESCRIPTION

1.1 This procedure describes the calibration of the Hewlett-Packard 8991AOPT003 Peak Power Analyzer. The instrument

being calibrated is referred to herein as the TI (Test Instrument).

NOTE

This procedure does not calibrate the Hewlett-Packard 84812A or 84815A peak power sensors commonly
used with the TI. To calibrate these peak power sensors, use NAVAIR 17-20GD-24.

1.2 This procedure was derived from a draft prepared by Naval Air Warfare Center, Aircraft Division (542800A), Patuxent

River, MD. All comments concerning this procedure should be directed to Measurement Science Directorate, Naval Warfare
Assessment Station, P.O. Box 5000, Corona, CA 92878-5000.
