The whole purpose of a GPSDO with an expensive double oven OCXO is to provide extremely high quality holdover performance when GPS signals go away. To achieve this level of performance one needs to compensate for the affects of temperature on the parts of the system outside the oven. 0.5C resolution is not up to the task of maintaining parts per trillion accuracy. There does not appear to be any other temperature sensor in the Tbolt --------------- I'm still not convinced. There's going to be another very important temperature sensor inside the Thunderbolt and that's the one inside the ovens, perhaps even two in a double oven. I understand where you're coming from but, given the apparent lack of evidence to support the sudden deterioration in performance your findings would suggest, does it not seem more likely that in fact this sensor is not involved in the conditioning process? regards Nigel GM8PZR _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
