Sorry, should have said "femtoseconds" here. Going from 10 Hz-100 kHz to 10 Hz-1 MHz with one OCXO plot I have contributes 1E-15 more jitter. The idea still applies, though -- just keep moving the upper limit higher until the difference doesn't matter in your application. With a high-qualty source you will not usually need to extrapolate beyond the boundaries of the plot. -- john, KE5FX _______________________________________________ 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.
