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; AN/GSM-287; or AN/GSM-440. Alternate items may be used

by the calibrating activity when the equipment listed in table 2 is not available. 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 also required for this

calibration: Crystal Detector, HP 432A and a 600 Ω termination.
