TB 9-6625-2259-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin provides instructions for the calibration
of Sweep Generator SG-1206( )/U. The procurement specifications for SG-1206( )/U ( A 3 0 2 3 1 3 0
dated 20 November 1986) were used for performance tests, and TM 11-6625-3231-40 was used
for adjustments and adjustment locations. 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 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. 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.
