EQUIPMENT REQUIREMENTS
4. Equipment Required. Table 2 identifies the specific equipment to be used in this
calibration procedure. This equipment is issued with Secondary Reference Calibration
Standards Set NSN 4931-00-621-7878, and Secondary Transfer Calibration Standards Set
AN/GSM-705. Alternate items may be used by the calibrating activity. The items selected
must be verified to perform satisfactorily prior to use and must bear evidence of current
calibration. The equipment must meet or exceed the minimum use specifications listed in
table 2. The accuracies listed in table 2 provide a four-to-one ratio between the standard
and TI. Where the four-to-one ratio cannot be met, the actual accuracy of the equipment
selected is shown in parentheses.
5. Accessories Required. The accessories required for this calibration are common
usage accessories, issued as indicated in paragraph 4 above, and are not listed in this
calibration procedure. The following peculiar accessories are required for adjustment only:
Serial interface assembly, Anritsu P/N T1678, or Special Purpose Cable locally procured
