Additionally, the outer heater on many commercially-available "double
oven" OCXOs -- including the DO 10811s -- is not on during normal
operation. It is only there to get the inner oven up to temperature
quickly, then it cuts out. This allows the inner heater to be
designed for lower output and finer temperature control, without
taking forever to warm up to operating temperature.
Best regards,
