I am happy to report that the offset problem I mentioned on Dec 28 is
fixed.
There were no responses to my request, but it might be helpful to others
should their 1992 get faulty in the same way.
Basically the A-input had a low leakage input protection diode (JPAD50)
that was, well, not so low lea
Hi,
Sorry if this question is a bit out of place. It is not about timing, but
more an electronics thing. But searching for Racal 1992 seems to get a lot
of hits here on this list.
I have just received a used Racal 1992 counter and are checking it for
proper operation. All seem fine except the chan
mine 1992 (S/N: 992064) mounts a
9462 (454879, REV A) 5MHz OCXO:
any more info about it?

Antonio,
I will have a look this weekend when I'm back home so I can read the
manual and/or open the counter to find the jumper...

Thanks, Harry, I already had got this info from this list, but had trouble
locating the jumper. The manuals seemed ambiguous, and I didn't find anyone who
actually made the change. May you help? Anyway, now my programs are MATE/CIIL

You can switch the mode to standard language instead of MATE/CIIL by
changing a jumper inside the counter.

In my experience limited to two units, the 04E works very well, and I've been
prudent claiming an aging of one part in 10E10 per day. I suggest to check your
unit. My reference was Rb (LPRO). They are both 02M.
The 02M has a tag on the left side looking from the front. If the tag was lost,

Hi,
A year or so back I had an unusual fault on my 1991 (160MHz version of
the 1992). After half-an-hour it would lock-up if you changed any
settings but was okay if you left it alone. Of course, after a cool-down
period, all went well until the next time.
Now for some reason I got it into my hea
Ed,Mine comes out of standby pretty much where it is going to be. I see from
information posted that I seem to have option 4E. Mine doesn't look quite
that good compared to GPS. I believe mine is an 02M model though there is
nothing on the unit to say so. The manual says the GPIB should be a 401820

Although the timebase appears to be stable, I've noticed that the

been on standby for many days. It takes a couple of hours
