TB 9-6625-106-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Synthesized Signal Generator, Anritsu, Model MG3695B, with options 1B
(rack mounts), 2C (step attenuators), 5 (RF coverage, with analog down convertor to 10
MHz), 6 (analog sweep), and 28B (full modulation suite) only. The manufacturers' manuals
and procurement specifications were 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 and microwave techniques.
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 Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
