IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Radar Test Set, AN/UPM-29A, TS-147B/UP, and TS-1335A.
The
manufacturers' manuals, TM 11-6625-917-15 and TM 11-1247 (Series) were used as the
prime data sources in compiling these instructions. The equipment being calibrated will be
referred to as the TI (test instrument) throughout this bulletin.
a. Model Variations. Differences among models are described in text.
b. Time and Technique. The time required for this calibration is approximately 3
hours using the microwave 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 Description. TI parameters and performance specifications which
pertain to this calibration are listed in table 1.
