Then pressure it into a small coin-sized pellet. Oh, the platinumplates we used for the ovenwork was nice... Cheers, Magnus

How well they can do this (ie: how small can they keep DUT1) depends on the quality of their science (and/or coin-flips) >I notice that this subject seems to make you a little grumpier than >the Poul-Henning I am used to. I hope I am not treading on ground >you feel already is too well covered.

I tend to think of the machine clock as being something that should keep ticking along one SI second to the next, keeping count of the seconds since some epoch.

the connection would have to be a minimal 3-wire serial (RS-232 or TTL/UART) https://en.m.wikipedia.org/wiki/RS-232#3-wire_and_5-wire_RS-232 Ground is easy to find, and TxD and RxD is a coin-toss (50:50) if you hook-up right. greg, w9gb === I thought I could answer this question (Acron Zeit) easily, since I had the cable right at hand.

The spec sheet for the 134-10 lists the short-term stability as < 1e-10 / sec, and both units meet this spec, with long-term aging at <1e-9 after 30 days, 5e-10 after 1 year, with both units also meeting this spec after 30 days.
