And this is where one question leads to another. For an oscillator that is
going to be used at very high velocities and accelerations, like in a missile,
would it be calibrated somehow under the target G force? Or would you just
compensate some other way? Or just not worry about it?

Hi
The answer to any complicated question is always going to be “that depends” …
You can indeed buy acceleration compensated OCXO’s. You can get them that only
compensate simple (DC) acceleration or that compensate vibration as well. It
all depends
on the requirements of your system.

Hi
All OCXO’s are sensitive to acceleration. Gravity is one form of acceleration.
A
sensitivity in the 0.5 to 2 ppb / G is not uncommon.

I left it on for over a week and it, ultimately, seemed to slow down in its
