Re: total newbie into GP-IB
If you're clever enough to figure it out, you can do a USB passthrough over ethernet
with Linux. I've done that in the past.
Not recommending that, just noting the point :-)

On the other hand, there seem to be more USB interfaces on the market than Ethernet interfaces.

Re: total newbie into GP-IB
Hi Ruben,
I guess it depends a lot on whether you want NI compatibility or not. In the latter case, you'll need to do some substantial coding work. I left Windows decades ago, so for me that was a non issue and I went for an original ProLogix GPIB-Ethernet, and coded almost all my equipment in Java.
Before that, I bought an Agilent GPIB-USB interface which lasted one lousy Friday evening. Counterfeit. Lesson learned.
Unfortunately, at ProLogix's current price point, I would seriously consider other options like DIY.

Anyways, just my 2 cents, admittedly somewhat from a developer's perspective.
Good luck with your choice/purchase,
Jan

For your 08460-60370 board you need to use the manual changes sheets pdf from 1984, with the 08640-90197 pdf bought from Artek, good luck with the repair.

David & GH thanks,
Sorry I replied to Jos before I saw your your answer GH.
Following the excellent suggestion of Jon above I downloaded the "HP 8640 B Service Manual Volumes 1 and 2 INC CCT Pn 08640-90215 May 1991 .pdf"
(Messy indeed! That's why I always prefer to buy the excellent searchable Arteks.)
I thought it was mine but no. It is only partly.
I then knew there were at least three different A10A2. I'll have a good look at the fourth now!
Thanks and I'll report here.

There are at least four versions of the A10A2 RF divider board, I've combined date code info from pictures of boards on the web and that messy manual pdf from 1991, the actual info the OP needs is in the 16th Feb 1984 manual changes pdf, not sure where I found that pdf;
A10A2
08460-60023 D-1339-4, D-1441-4, E-1712-4
08460-60092 service exchange by HP, rebuilt of above 08460-60023
08460-60370 A-2118-4, B-2314-10
(change 5, s/n 2118A to 2403A, from manual changes dated 16th Feb 1984)
08460-60383 ?
(change 27, s/n 2404A, s/n 2408A, from manual changes dated 16th Feb 1984)
(s/n 2520A to 2828A)
08460-60483

Re: 11048C feed through termination data?
Well,? Wikipedia does not have any reference to support that. As you imply they are not always correct. Certainly entrys on things I have direct knowedge of have errors.?
Also see
I'm not disputing that the gentlemen may have had involvment, just the naming. I was taught the connector types formally over 40 years ago and there was no mention of Neill or Concelman. They were C type, N type, Baynet N Compact and Threaded N compact.
I think the naming was probably introduced by advertising (probably by Amphenol) in the late 20th centuary and has been propagated and "validated" by the internet. It's a good story.
So many times when trying to find obscure information on the internet I find that lots of sites say exactly the same thing (often dubious if not outright wrong) and further digging indicates it all came from one unverifid source. When I say exacty the same thing that can be letter for letter including spelling mistakes.
Late breaking:
I found this 50's Amphenol catalog
It does not mention N type connectors but it does have UHF which the Amphenol series is 83. There is also a L"arge" UHF in single and twin contact (never seen that before). If Ampphenol invented the N connector in the 40's ou would have thought it would be mentioned. Of note is ann the Amphenol connectors have number "series" indentification, not letters.
Robert.

Thanks Jos. The 08640-90197 manual is also what I got, but in pdf through Artek. Do you refer to:
"Figure 8-38. A10A2 RF Divider Assembly Component Locations."
and: "Figure 8-39. RF Dividers Schematic Diagram" ?
This is the older board (first one on my initial post) but I don't find the second board on that manual.
Do you have more please?

As said earlier the archive serial N is 125 while mine is 2482 and it looks like there are serious differences between the two models.

Re: 11048C feed through termination data?
BTW, I just referenced Wikipedia, that on-line source that is?ALWAYS correct (tongue firmly in cheek) . It attributes the BNC, TNC, N and the C connector to Neill and Concelman. I forgot the C, Concelman's contribution. This leads me to believe firmly that they were named for the inventors, re-affirming Dick Knadle. BNC to 4 GHz.
Look at Wiki for the N which it says is named for Neill.

Joe,
?I have a defunct 1740A parts unit, would you be
interested in the whole thing? It looks like someone long ago
butchered the low voltage power board, but the switch assy looks
ok. Located just North of San Diego, Ca. I'm not doing anything
with it, let me know if you can pick it up. It's a lot to ship
for the "value", what ever that is.

My HP-143A (the large-screen member of the 140 family came in a cardboard box with no padding. Aside from the CRT being broken, the frame members were bent such that the plug-ins were very tight. I eventually managed to free them but it was always a challenge going forward. Replacing the CRT was another matter¡ªtook about a year to track one down. The seller (claimed ¡°a friend¡± packed it for him) refunded most of my money.?

I thought I would never get the amplifier out of mine and ended up having to remove the bottom cover just to get enough push to free it.? I suspect it is the alignment pin that's too tight in the hole but it could also be the connector.? I tried a bit of sanding with a 1/4" dowel and some silicon carbide paper to smooth the surface of the hole and I think that helped but it is still rather tight.

The screen photo's in that HP140B add, appear to show a Z axis problem?
(blanking, or not.)
The impression of a square wave I think, is caused by the timebase?
triggering on the incoming power line frequency (50/60Hz) with the sweep?
speed high enough (10uS/div) to see the vertical A/B "chop" signal, with?
the brightness turned up high enough to see the low duty trace, but the?
sweep blanking might not be functioning correctly, and/or the CRT bias?
setting is out of adjustment.
Probably fixable, the rest of it looks clean, save for a dent in the top?
cover.

there for the past day job.

Hi Jeff,
a 0.01" (10 thou) delta does not sound like much on it's own, but in this case it is 20% oversize, That's like trying to screw a M10 nut onto a M12 bolt.
At worst case design limit it is 0.011 to 0.014" oversize.You will damage a good quality TNC/BNC female by pushing a N male into it.
On naming, I've no reason to be jealous but very few military connectors are named after their designers. The truth is probably lost in time. I've never been able to find any contempary documentation to support either way.
