1250 seconds at 50Hz = 62500 periods.
Assume one extra period over 1250 seconds: 62500 + 1 = 62501
Hi All
Apologies to any who may receive multiple copies of this but I thought it
worth sending to those lists where I've previously seen mention of this
meter.
I have now had two identical failures of Schaffner filtered mains sockets
on ex-mil 7150plus DMMs, although I'm not suggesting th

Hi,
A fellow amateur and I have just put together the GPS-based frequency
reference published in the "Every day Practical Electronics" issue of
April/May 2009 and are both experiencing the same problem. The type-3
phase comparator of the 74HC4046 has both 1-pps and 50kHz DC-coupled
inputs designed

particularly relevant.
In both cases there has been an internal component failure within the mains

And a FYI - it was 60 hertz power here

Never let flimsy details like facts derail a perfectly good theory.
(That's about 13,33 ppm BTW)

Gentlemen,
has anyone of you ever experiend problems with the ALC regulation loop of a
HP8660C/D synthesizer that had its origin in a problem with the level
