EQUIPMENT REQUIREMENTS
calibration procedure. This equipment is issued with Secondary Transfer Calibration
Standards Set AN/GSM-287, Microwave Standards Kit Drawing 13335458. 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 parenthesis.
