[time-nuts] EIP 371 counter

I’m trying to put a EIP 371 into talk only mode but have zero documentation. Anyone know how to do so so that we can characterize a few oscillators? Thanks! Bob ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com

Re: [time-nuts] Favorite counters (current production)?

Hi Don’t get me wrong here, I think the SR620 is a great counter. My concern is that the design came out a *long* time ago in terms of solid state generations. If things work out as they often do, some random part in there is going to go obsolete. What part and when, I have no idea. HP has alwa

Eric -- Thanks much for that posting. List -- If you are interested in a summary of optical and lattice clocks, see: "A New Era for Atomic Clocks" https://phys.org/news/2014-02-era-atomic-clocks.html https://www.nist.gov/news-events/news/2014/02/new-era-atomic-clocks I also highly recommend this
