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,
NSN 4931-00-621-7878. 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 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 the
calibration procedure. The following peculiar accessories are also required for this
calibration: 2 watt, 20 dB attenuator, 50 , Tektronix, Type 011-0059-02 (011-0059-02).
