No, I disagree. That's not carrying things nearly far enough. I really think we should figure out a reliable methodology for this sort of thing. This is time nuts after all, so perhaps some time/frequency applications might end up needing sub-nanovolt regulation (and there are those whom might simply "need" it because they're nuts) Tom Van Baak, Thursday, January 31, 2013 9:43 AM (Local NY time): ((...snip...)) > I was never quite satisfied with the outcome of comparing a half dozen power > supplies this way: > http://www.leapsecond.com/pages/tbolt/noise.htm > > We have rigorous ways to compare and report oscillator performance; both as > numbers and as plots. Is there something equivalent for power supplies? Thanks Tom. I found that writeup about various power supplies rather useful. I'm doing some research and development for power supplies right now, and hope to come up with something completely nuts by the time I'm ready to go from learning how to work with thunderbolts / GPS Disciplined OCXO to something exotic which, today, might be far over my head. --Sarah _______________________________________________ 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.
