SECTION 1
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.
1.3 This procedure includes tests of essential performance parameters only. Any malfunction noticed during calibration,
whether specifically tested for or not, should be corrected.

EQUIPMENT REQUIREMENTS
NOTE
Minimum use specifications are the principal parameters required for performance of the calibration, and are
included to assist in the selection of alternate equipment, which may be used at the discretion of the using
laboratory. Satisfactory performance of alternate items shall be verified prior to use. All applicable
equipment must bear evidence of current calibration.
The instruments utilized in this procedure were selected from those known to be available at Navy calibration
facilities, and the listing by make or model number carries no implication of preference, recommendation, or
approval for use by other agencies. It is recognized that equivalent equipment produced by other
manufacturers may be capable of equally satisfactory performance in this procedure.

Throughout this procedure, TI “hardkeys” are those on the front panel, while “softkeys” are those blank
buttons on the side of the TI display for which the TI display will indicate the “softkey” name according to the
current menu selection.
3.1 Ensure that all power switches are set to off, and set all auxiliary equipment controls as necessary to avoid damage to the
equipment and so that dangerous voltages will not be present on output terminals when the power switches are turned on.
3.2 Verify that the N-type connector of the TI sensor check source conforms to the MIL-C-39012 composite specification
(0.187” to 0.207”) as follows:
As required Local supply

PRELIMINARY OPERATIONS
NOTE
3.2.1 If the coaxial gage has been standardized with a MIL-C-39012 master gage block, verify that the gage dial indicates
between -0.020 and 0.000 inches.
