TB 9-6625-2343-50
IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin provides instructions for the
calibration of Measuring Receiver, Hewlett-Packard Model 8902A. 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 8
hours, using the dc and low frequency technique.
2. Forms,
Records, and
Reports
a.
Forms, records, and
reports required for calibration personnel at all
levels are
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).
3. Calibration
