Initial frequency-temperature accuracy (one-half temperature cycle): Verification applicable. 1/ Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23C 1C, immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments over the specified operating temperature range. 1/ 1/ For the purpose of transitioning this device to MIL-PRF-55310, ‘Frequency stability versus temperature’ has been renamed ‘Frequency-temperature tolerance’. The verification requirements of ‘initial frequency-temperature accuracy (one-half temperature cycle)’ shall apply except that frequency measurements shall be referenced to the frequency measured at +23C 1C (fref) instead of to the nominal frequency (fnom). 2 MIL-PRF-55310/9J TABLE I.
