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 +23C 1C (f
ref
) instead of to the nominal frequency (f
nom
).
