1. Initial calibration @ 25°C
2. Frequency vs temperature stability
3. Inclusive of calibration, operating temperature range, supply voltage change,
shock and vibration, and 10 years aging.
4. Measured @ 25°C, within 5 minutes, the unit will be within ±0.1 ppm of its reference
frequency, measured after 30 minutes of continuous operation at a stable 25°C
