IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification.
This bulletin provides instructions for the
calibration of Pulse Generator SG-366A/U (Kay, Model 5070B). 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. There are two versions of SG-366A/U. The adjustments for
version A are located on top view of the chassis. Version B and model 5070B are the same
for calibration purposes, and adjustments are located on both top and bottom views. Some
early models of model 5070B show different adjustment references for the same locations.
These reference designations are not shown on the figures. Some adjustments for version B
are located on the power supply assembly but are not related to the power supply function.
Where adjustment locations are the same for both versions, they will be shown on version
b. Time and Technique. The time required for this calibration is approximately 3
hours, using the dc and low frequency 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.
