EQUIPMENT REQUIREMENTS
4. Equipment
Required. Table 2 identifies the
specific equipment to be
used in this
calibration procedure. This equipment is issued with Secondary Reference Standards Set,
AN/GSM-286. 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.
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 accessory is also required for this calibration:
Extender, Tektronix, Type 067-0589-00, and Standardizer 5-80 pF, APN 7916146.
