The temperature you see is not from the OCXO but from the thermometer chip near the RS-232 connector. The DS1620 is probably at fault and the rest of the Thunderbolt is operating as it should. I've see a lot of Thunderbolts and the most common failure mode of the non E revision DS1620 thermometer is for them to display -55 degrees C although it could just have erratic output like yours. The erratic temperature that it is reporting could cause the processor to try to compensate for the erratic jumps and cause the Thunderbolt output to be less stable. The DS1620 should be replaced. -Arthur _______________________________________________ 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.
