Bob, you of all people must be able to answer this:
OCXO's have specified temperature ranges for instance
-40...+70°C for the heavy duty stuff.
But I cant imagine the ovens used are so perfect that they have the
same regulation performance at all temperatures.
I can choose the exterior temperature, which I should prefer ?
Disregard aging of electronics and materials, we all know that
stuff, what I'm interested in is at which exterior temperature
OCXO ovens work best ?
