I, personally would have expected the isotemp oscillators to perform better than the HP signal generator. The paper shows that measurements made with the counter are too optimistic.
Do you have other really good oscillators you can measure such as a HP10811 and also an Austron and perhaps a high-end Wenzel? Maybe you could borrow these just for measurements. I hate to say for sure that the Isotemps are so poor until you use your same counter to measure other oscillators. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
