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 Sets, AN/GSM-287; AN/GSM-286; and AN/GSM 440. 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 is shown in parentheses.
5. Accessories Required. The accessories required for the 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 also required for this calibration: 50 Ω
feedthrough termination, Hewlett-Packard Model 11048C, and crystal detector, Hewlett-
Packard Model 423A.
