One thing you can do with a Thunderbolt is to let it settle into to disciplined equilibrium to 10.0000000 MHz, check the DAC voltage serring, and then switch off disciplining and manually control the EFC DAC. This will improve the phase noise at the expense of frequency drift which may or may not be an issue/compensatable for your application.
The standard Thunderbolt oscillator has excellent phase noise characteristics but is very sensitive to temperature changes. Lady Heather's PWM'ed fan based temperature control can be quite useful for minimizing the effects of temperature changes. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
