Hi,
Usual (best?) is supply slight over voltage and use LDO/RC filtering in

24v/12v/5v/-12v (with some margin 10%?) or converting some single supply
of 24v or 48v in each unit to required

Hi
Well, I’m sitting here plotting the stability of some eBay “frequency
standards”. The one thing I *can*
measure is just when the power cords get bumped.
As long as you can hold sub mili-volt sorts of stability on the supplies “as
delivered” it pretty much does not
matter how you get
I have been addicted to home brewing GPSDO, Rubidium, OCXO, and etc, etc, etc.
I don't mean making of these from scratch but taking a surplus unit and encase
them in ready-to-use form. Most of them are in U2 rack case.
One part of it that I really do not like is constructing a power supply
Dear fellow time-nuts,
I'm launching a measurement effort at Cloudflare Research to monitor and
evaluate the performance of NTP and NTS servers from multiple vantage
points. The goal is to create and open, distributed monitoring system, with
plans to inform IETF efforts as well as the research
