5) Inclusive of operating temperature range, supply voltage change, load change, shock and
vibration, 20 years aging, Vc=2.18V, initial calibration.
6) 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
7) Referenced to Fo @ 25°C, Positive Transfer Characteristic.
