/ 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
) instead of to the nominal frequency (f
