SECTION I
IDENTIFICATION AND DESCRIPTION
1. Test Instrument Identification. This bulletin
provides instructions for the
calibration of Dual Trace Delayed Sweep Sampler, Tektronix Type 5Sl4N. The
manufacturer's manual was used as the prime data source in compiling these
instructions. The above equipment 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 4
hours, using the dc (direct current) 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) follows the
designated adjustment. Report only those adjustments made and designated with (R).
3. Calibration
