TB 9-6625-2094-24
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Signal Generator SG-1170/U (Wavetek, Model 3001). 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
(1) Wavetek, Model 3001 (unmodified) frequency range is from 1 MHz to 520 MHz.
(2) The SG-1170/U (modified) instruments have a frequency range from 1 kHz to 520 MHz.
(3) SG-1170/U (unmodified) instruments have a frequency range from 450 kHz to
520 MHz.
(4) Frequency ranges for a particular instrument are shown on the front panel,
located above the FREQUENCY indicator switches.
b. Time and Technique. The time required for this calibration is approximately 4
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.
