You do not want to depend on an instrument that will switch its reference willy nilly while you take measurements.
Have a switch so that you have some control on what is happening. Sometimes too much automation is just complication without justification.

I want to feed it with an external OCXO, but I don't want to completely replace the TCXO. Here is the scenario. On initial power on, or after a power loss, I want the internal TCXO to be used. Once the OCXO is up, I want to switch to it. How could this be done easily and cheaply?
