IDENTIFICATION AND DESCRIPTION
1. Test Instrument
Identification.
This bulletin provides instructions for the
calibration of AVA Calibration Test Set, Scientific-Atlanta, Inc., Part Number 29085800.
The manufacturer's manual was used as the prime data sources in compiling these
instructions. 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 1
hour, 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. Appendix A is a duplicate copy of table 3, located within the text,
which requires annotation. This table may be conveniently reproduced locally.
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).

EQUIPMENT REQUIREMENTS
4. Equipment
Required.
Table 2 identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-286 or AN/GSM-705. Alternate items may be used by the
calibrating activity. The item selected must be verified to perform satisfactorily prior to use
and must bear evidence of current calibration. The equipment must meet or exceed the
