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
).
