Sorry the FE-5680A 1PPS is of course on pin 6, not pin 3.
Still, about 1uS long only. Pin status 3 did not change on mine.
Low all the time.

Aging is a composite of phenomena sometimes resulting in a negative rate
and sometimes in a positive rate (most common). Some causes that haven't
been mentioned in this thread are the slow release of stress in the
crystalline structure created by shock or temperature excursion, and the

What do you mean by that? I don't see the connection with USA 193.

I'll second this. I'm kind of fond of the MCS-51 family for 8 bit
applications. They're really nothing special, old school stuff, but
they have something like 40% of the embedded market, and once you

I'm not familiar with the E1938, but the 10811, I believe is one of the
small hi stab units that HP put into their higher end counters. It uses a
single oven where the 103 and 107 used double ovens. Incidentally, the 103
uses a 1 MHz rock and the 107 uses a 5 MHz rock.
