ORDERING INFORMATION
Notes:
1) Initial calibration @ 25°C
2) Frequency vs. temperature stability
3) Inclusive of calibration, operating temperature range, suppl y voltage change, shock and
vibration and aging (20 years).
4) Specifications at time of shipm ent after 48 hours of operation.
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.
