EQUIPMENT REQUIREMENTS
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
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
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: Termination, N Jack, dc to 5 GHz, 50 W, Sierra, Model 161A-50 (161A-50) and
Low Pass Filter, Telonic, Models TLC125-6EF1 and TLC75-6EF1.
