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

(see Appendix A), Instrument Controller.
