TABLE I. Dash numbers and operating characteristics.
Frequency-temperature tolerance (one-half temperature cycle, referenced to frequency measured at +23
C 1C,
immediately prior to starting of the test): See table I. Measurements taken at ten equally spaced increments over
the specified operating temperature range. 1/
Frequency-voltage tolerance:
1 ppm maximum for a 10 percent change in supply voltage. Measurements taken
at reference temperature and operating temperature range end points.
Frequency-load tolerance:
1 ppm for a 5 percent change in oscillator load.
Frequency-ambient pressure tolerance:
1 ppm sea level to 70,000 feet.
Frequency aging: Measurements shall be taken at +70
C 0.2C at intervals of not more than every 72 hours for
30 days minimum.
1 ppm per 30 days, maximum.
1 ppm per 60 days, maximum. 2/
Terminal strength:
Method 211 of MIL-STD-202 , test condition C.
Applied force: 2 pounds each terminal.
Bends: Five at 45 degrees each.
Frequency-environmental tolerance: Not applicable.
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
).
2/ This is a performance requirement of the oscillator. Support data shall be presented showing that this
requirement shall be met.
