Hi!

I recently bought an old 8590A on eBay. It works fine, but the HPIB/GPIB connector and cable are missing. The cutout has a adhesive blanking plate over it so it seems that the cable was advertrntly removed at some point. The card is there and appears to be working as the analyzer recognises it. The cable is a standard IDC 24 pin to GPIB as far as I can see. Pinout of the IDC connector is not the standard GPIB one though, but I have traced the connections and documented. I have two questions:

1. Does anyone have a schematic of the board or cable so I can verify what I have documented?
2. How is the cable supposed to be routed inside the unit? There is not an awful lot of free space.

Thanks in advance!

No one else has this question

It sounds like you need what is pictured in the attached drawing from the service guide. There is a ribbon cable attached to a board that also has the rear panel GPIB connector attached to it. From the service guide it looks like the part number of this assembly is 08590-60018. Sorry, but I couldn't find any schematics for this at all, but this should solve the mystery of how the cable gets to the rear panel connector...

I did a google search for the part number and I did see at least one hit come up that appeared to be a legitimate offer for one for sale.

Best regards,
Mike

Thanks a bundle. Dunno why I did not find that in the service guide? (0850-90316, the only one I could find on the web). Anyway, If I can find a complete cable and bracket, for a reasonable price, then it is so much easier. I will look.

Ah.. Because it was the wrong manual. The correct one is 08590-90109:

I Guess the manual for the 08590-60052 GPIB OPT Kit would contain wiring instructions, but I have been unable to locate it on the web.

OK. Made some progress, cable pinout seems to be:

1,2,3,5,7,9,11,13 = gnd
4 atn
6 srq
8 ifc
10 ndac
12 nrfd
14 dav
15 ren
16 eoi
17 d8
18 d4
19 d7
20 d3
21 d6
22 d2
23 d5
24 d1

I found one vendor that offered the cable+bracket for just over 50$, ut they have a minimum order of 200$ and shipping will set me back an extra 50$. A gpib connector and an IDC one will set me back less than 10$ :)

Wonder if the cable should be screened? OTOH should the be no emissions from the GPIB cable when idle.
