I recently purchased an HP8644B with options: 01, 05, 11. I have executed ILD diagnostics and need to execute module / cable level tests. Unfortunately, I do not posses the service kit to further diagnose the problem . Does anybody have the cable test board or schematic of the cable test board in order to build the assembly?
Hi Will02,
Normally, the schematics would be locked to the public, but since the 8644B has been obsolete for a while, we are able to share the following attachments with you (see attached schematics). It may be difficult to locate a replacement service kit, since this product is obsolete.
Note: These schematics might not be able to help if you do not know how to connect the service kit to the instrument. For help, please contact our extended service team for the 8644B:

If you wish to speak with someone on the phone, call the toll-free number: 1 (800) 829-4444 Press #, then 2
FYI, If you are thinking about upgrading, check out this instrument:

Hello Will,
I've worked on this model for many years, and have never needed the service kit. I've only seen scattered remnants of old kits here and there. The service guide always suggests cable tests, but I've never seen any cable failures in this model. If you just perform the other testing using the internal diagnostics, it should lead you to the problem.
