Notes:

1.

Terminology and test conditions according to IEC60679-1 and MIL-PRF-55310, unless otherwise stated

2.

Allows for any and all degrading contributions, including initial tolerance, temperature stability, supply

and load change and aging

3.

For other vibration profiles please consult factory. For lower PSD level of 0.01 g²/Hz, 20 ~ 2000 Hz the

phase noise under vibration will be 10 dB better.

4.

Oscillator is within specification limits
