TB 9-6625-2258-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Programmable Sweep Generator, Wiltron, Model 6669M. Procurement
specifications (A3023130, dated 20 Nov 86) were used as the prime data source for the
performance paragraphs and the manufacturer's manual was used for adjustment
paragraphs. 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 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. 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.
