ORDERING INFORMATION
1) Initial calibration @ 25°C
2) Frequency vs. temperature stability, 0 to 70°C absolute.
3) At the time of shipment after 48 hours of operation.
4) Inclusive of calibration, operating temperature range, supply voltage change, load
change, shock and vibration, 10 years aging.
5) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference
frequency, measured after 30 minutes of continuous operation at a stable 25°C
