Gang,
Thanks for the input. I never seem to hear any discussion about the
5345A so I thought that maybe there was something about the
HP-5345A's that was not in favor - for some reason. Glad to know
that's not the case. I paid about $300 for my 5345A about 8 or so
years ago with a complete service manual. It was working when I got
it and it has the Hi-Stab oscillator. I've had it apart a few times
to clean, edge connectors and all, and I think it's about time for
that again. This time I'm going to replace the fan. It's starting
to become noisier than just high velocity noise.
I used to have a HP-5425A and still have 3 or 4 plug in's from it. I
see one of the adaptors on eBay that looks pretty clean for
$495. What is a fair price for the adaptor?
Thanks again for your input.

Subject: Re: [time-nuts] Speaking of counters...
other then big, noisy and somewhat of a power hog, they to me are one
of the best bargains out there if you don't have a big budget.
HP Journal that talks about them

if your not in a hurry and you use GPIB or think you will in the
future, look for option 12. I have
seen fully working 5345As go for as little as $25 on the E. One day I
went to do a local pickup
of a piece of Tek gear and the guy had about 10 5345A's all not
working from a DOD sale. I went
home with a full pickup for $50.
001 - Room Temperature Time Base
010 - General Purpose Interface ( gpib format, talk only)
011 - General Purpose Interface (Digital I/O plus control of all
functions except input amplifier)
012 - General Purpose Interface (similar to option 011, but adds slope
and level control)
Where I will never give mine up is the combination of the 5355A
plug-in and one of the 5356A/B/C
heads. It brings the counters input as close as you want to your work.
You do have to be careful on getting a non damaged head
There is 5245A that will take you to 4Ghz. and an App note

Lastly there is the HP10590A plug-in adapter that lets you use the
5245 plug-ins. For me I use
the Video plug-in and one that I made myself from a gutted one.
Lastly there are S/N ranges but I can't remember them ..
