SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin provides instructions for the level A
and level C calibration of Dual-Trace Amplifier, Tektronix Types 3A1 and 3A6. The
manufacturer's instruction manuals were used as the prime data source in compiling these
instructions. The dual-trace amplifier will be referred to as the "TI" (test instrument)
throughout this bulletin.
a. Model Variations. Variations among models are described in text.
b. Time and Technique. The time required for this calibration is approximately 2
hours, using the dc and low frequency technique.
2. Calibration Data Card, DA Form 2416
a.
Forms. records, and
reports required for calibration personnel at all
levels are
prescribed by TM 38-750. DA Form 2416 must be annotated in accordance with TM 38-750
for each calibration performed.
b. Adjustments to be reported on DA Form 2416 are designated (R) at the end of the
sentence in which they appear. When adjustments are in tables, the (R) will follow the
designated adjustment. Report 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.
