Cal Authority Notes

Elmendorf-Richardson JB AK, Hill AFB UT, Holloman AFB NM, Otis ANGB MA, RAF Feltwell UK, Robins AFB GA, Tinker AFB OK, Wright-Patterson AFB OH N2 Any item listed as N2 in the Cal Interval clolumn is Precise Time and Frequency and will be calibrated as follows:

(1) Frequency standards employing rubidium or quartz oscillators are calibrated to the manufacturer 6 month accuracy specifications. This accuracy specification may be found by multiplying the long term stability rate listed in T.O. 33K3-4-2133-1 (or other appropriate specification) by the number of time intervals necessary for 6 months. If the long term stability is given per day, multiply the value by 180 days; if the long term stability is given per week, multiply the value by 26 weeks; if the long term stability is given per month, multiply the value by 6 months. This gives the accuracy of the TI during its calibration interval regardless of the actual length of the calibration interval. The calibration procedure is T.O. 33K3-4-2133-1, the calibration responsibility is PMEL and the calibration interval is 6 months.

(2) Calibration authority for all cesium beam frequency standards and cesium beam clocks shall be determined on an individual item basis as follows: Units used for frequency only will have a calibration authority of ABSOLUTE. Cesium standards used for frequency only may be certified by either the PMEL or the TRC. Units used for time will require a time synchronization using T.O. 33K3-4-2133-1 as the calibration authority. The calibration responsibility is PMEL and the calibration interval should be set to satisfy the timing requirements of the User.

(3) Frequency Standards in a system that are continuously adjusted or compared to a Frequency Source which is referenced to NIST via their FMAS (Frequency measurement and analysis service) (such as GPS, CONUS Loran, etc.) will be given a Calibration Interval of NCR.

N67 Any item listed as N67 in the Cal Responsibility field may be calibrated with National Instruments Calibration Executive (NI Cal-Exec) software. PMELs using NI Cal-Exec shall verify the Procedure Version listed on the Calibration Performance Test Data report matches the Procedure Version in the Cal T.O. field of AFCAV.

If the Procedure Versions do not match, PMEL must perform a Val/Ver IAW TO 00-20-14 and submit the data on an AFTO 22. Unlisted items require the PMEL perform a Val/Ver IAW TO 00-20-14 and submit the data on an AFTO 45. If no suitable WUC exists, but the same PN has a Procedure Version in the Cal T.O. field, a Val/Ver is not required; however, an AFTO 45 is required to have an appropriate WUC assigned.

PMELs listed below have NI Cal-Exec. Recommend contacting the calibration PMEL to ensure all required equipment and adaptors are available before sending. PMELs without NI Cal-Exec may perform a manual calibration using the Calibration Report and Manual Calibration Procedure, or contact a PMEL with NI Cal-EXEC for lateral support. For Table 1 Specifications, see WebAFCAV - Technical Data - Calibration Performance Test Data.
