2FS is 10 times the TIME/DIV OR DLY TIME switch setting.
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-286; AN/GSM-287; or 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.
5. Accessories Required. The accessories listed in table 3 are issued as indicated in
paragraph 4 above and are used in this calibration procedure. When necessary, these items
may be substituted by equivalent items, unless specifically prohibited.
