IDENTIFICATION AND DESCRIPTION
This bulletin provides instructions for the
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.
prescribed by TB 750-25.
b. Adjustments to be reported are designated (R) at the end of the sentence in which
they appear. When adjustments are in tables the (R) follows the designated adjustment.
Report only those adjustments made and designated with (R).
pertain to this calibration are listed in table 1.
