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 and 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 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 accessories are required for this calibration:
Calibration Element, Bird Electronic Corporation, Model 4410-070, and 50 Ω termination
supplied with TI.
