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. 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
accuracies listed in table 2 provide a four-to-one ratio between the standard and TI.
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: Circulator, P/N 7916840 (5985-01-217-0286), and Variable Attenuator,
