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-287, 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 provided 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 parenthesis.
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 the calibration:
Semiconductor Device (coaxial crystal detector), Hewlett-Packard, Model 423AOPT03.
