It's NASA property and not likely to be excessed. You'll wait in vain.... <grin>

For many aspects of Time and Freq related work I do close in Phase Noise is a primary concern. If you ever decide it is not needed let me know I and I am sure many other "Time Nuts" would be interested.

Interestingly, it seems it's not that wonderful, compared to a $200 Wenzel streamline, except for "real close in" FTS1050 Wenzel 1 -116 -105? (est from 1/f^3 and 10 Hz offset) 10 -140 -135 100 -150 -155 1k -157 -165 10k -160 -165 I note that John Ackerman reports on https://www.febo.com/pages/oscillators/fts1050a/old/ a similar observation I suppose that you use these things for "close in" and ADEV performance, not for phase noise at 10 kHz out. Some of these units were modified at the lab to replace the original oscillator with a better one (a BVA, it's rumored). And who knows what else was done.. _______________________________________________ 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. _______________________________________________ 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. _______________________________________________ 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.
