I just recently sold my IBM Type 37 to a collector in the Los Angeles area. I

If you don't need the 26 and 19.2 to be exactly phase locked to the

that you go straight digital. There are a number of simple divide,

frequencies directly. The main

They are not like the US meters, but interesting.
BTW, Google Translate works fine on the text and helps a lot.
OTOH, it is hard to see the benefit of such meters to the utility, because

If the computer used for this is also running "ntpd" the computer's

Hello 50 & 60 Hz nuts,
The recent discussions here on measuring the mains frequency and
phase prompted me to revive an experiment I set up some 3 years ago.

Hi
What you probably will wind up with is a bit wider PLL bandwidth than 50 Hz.
The noise floor of your dividers and your phase detector will need to be
below that of the BVA. If you divide by 10, then the 20 log N works against
you in this case. Take a look at the phase noise numbers on the OCXO
Hi
There may be different behavior with different firmware versions. I do know
that a *lot* of 53131's behave exactly as described (like over 40 of them).
