Hello Time-Nuts,
A while back I acquired an HP 53131A, and a bit later added one of the
Chinese knock-off 3GHz prescalers. Makes for a nice counter except
for the very poor standard timebase. So, While researching the Option
010 and finding how outrageous the prices are running I found an
Option
Hi
Be careful about air flow. Those counters have heat issues even in the stock
configuration.
The Rb is a bit of a power hog so it heats up as well. Not saying it won’t
work, only that
you need to be sure the air is moving in the right places.

I recently got a strange little 1U FEI rack mounted unit called an
FE-7923F-100-1,
which appears to have rear 10MHz and dual 100Mhz outputs. it is called a
Frequency Reference Unit.
sadly, my unit has a fault light, and no outputs. All the internal supplies look
good, and there is an FE-83AA
start with the power supplies, and go on until morning...

Some time ago bought one on Ebay for under $50 just because it looked
interesting. It isn't a prototype but most of the FEI units probably
had limited production. It seemed to be more complicated than I
expected it to be but if I understood it better it would make more
sense.
The 10Mhz board is en
