Hal there is not one straight answer, as mentioned before these units are
intended for commercial applications with large temperature ranges. Most
have added frequency compensation using heater current sensing for C field
adjustment or in the case of the FE 5680A DDS control. Looking close at the
5680 you can expect 4 E-11 per 1 C.

What's the temperature sensitivity of the typical telco-surplus Rb unit?
