I'm new here, but you may get some ideas from this page if you find nothing
that directly fits your needs.

Hi,
I also use a HP 53131A counter and find it to me the nicest, most stable
counter that I have used to date. It is amazing how versatile this counter
is and how stable when using an gps external reference.
Other counters I have or have had are the HP 5370B, 5334, 5335, and various
5328's.
I
I just pull the board (it's fairly obvious how, but I believe the manual
also talks about how to disassemble the front panel), take the sliders out
of the switches, and swab everything down with Caig ProGold.
The only tricky part is paying attention to how the springs are installed on
the switch s
Could someone please provide me with a link or the procedure to disassemble,
cleaned / lubed.
Thanks
Jeff

Jeroen et al,
Apologies for my late reply to this message - I've been out
of the country for a week. I managed to get a copy of some 5680A
documentation from John Cuthbertson at FEI. It is a Word document,
and specific to the units with "Option 2", but it might be of help.
It is in a
It's normal for those last few digits to bounce around when measuring
frequency. The shorter the gate time, the less-consistent the LSDs will be.
How do the tolerances compare to what's in the manual's self-check
procedures? You'll note that they don't tell you to expect 10.000 000 000
MHz, but 1

I got a HP 5370A off of Ebay and although it looks terrible I thought it
would probably work OK.
But it doesn't :-( I downloaded the manual and have yet to print it out.
Question;
When doing a self check by feeding the 10 MHz from the back into the
counter it counts cycles OK
but the last 3 or
Hi Had:
Me too. Tje SR602's 16 digits always arranged the same way is really
nice. A mostly real front panel with limited levels of menuing is OK.
Got rid of my 53132 because although it could do very fast frequency
measurements, it offered no advantage when doing time interval
measurements.

I have to go with the SR620 of the TI counters I have available, HP
5316B, 5370B and 5372A, the first one that gets an input is the
SR620. They all run off of external time bases but I just like the SR620 best.

It's a book about Alfred Loomis.
I remember (forgive my old memory) reading about his use of 3 pendulum
clocks and his discovering that varying the proximal distances had an effect
on drift.

I would be interested in seeing the aryicles.

Hi All,
For over 12 years I have been running a HP53131 12 digit counter and the
freeware Agilent IntuiLink Connectivity Software via an old NI IEEE-488 GPIB to
Ethernet.
