IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
1. Test Instrument Identification.
calibration of the Power Meter, Giga-tronics, Inc., Model 8542 and Power Sensor, Giga-
tronics, Inc., Model 80301A. The manufacturer's manual was used as the prime data
source in compiling these instructions. The equipment being calibrated will be referred to
as the TI (test instrument) throughout this bulletin.
a. Model Variations. None.
b. Time and Technique. The time required for this calibration is approximately 4
hours, using the dc and low frequency and microwave techniques.
2. Forms, Records, and Reports. Forms, records, and reports required for calibration
personnel at all levels are prescribed by TB 750-25.
3. Calibration Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
