Agilent 54835A scope (4 channel 1GHz / 4Gs/s) repair & uphack

Just adding this here in case it's useful to you:
--- Quote from: free_electron on July 09, 2017, 07:17:48 pm ---you can launch scope.exe using the service command " scope.exe /service" that gives extra options in the self test menu where you can set attenuator click and othe roptions
--- End quote ---
Also you should be able to use the link to the scope software to upgrade to Win98 - I'm not sure what the experience will be like but I'd check the PDF that describes the process and limitations first.

My scope on the way to my home, should be here in about 2 weeks.

Ran the scope app with /service option and got boatload of new fails, too many to mention. Opened the case to have a quick look inside but saw nothing obvious.
Well, atleast the external display works :)

Trying to make room on my desk to start proper inspection, supply voltages and bypassing attenuators by feeding signal straight to hybrids etc.
What needs to be removed to get the attenuator modules out?
JanNousiainen:
Still cleaning desk (and installing more sockets to lab etc) to be able to start proper debugging >:(
Being overly optimistic, ordered some 64 MB of RAM in addition of current 16 MB to allow Windows 98 to run which is required to run later SW. Where can I find the update images/files? I think I need IDE CD-ROM too?

I used a parallel port CD-ROM drive I bought from eBay ("MicroSolutions Backpack Parallel Port CD-ROM Drive", I paid $14 for it but I took a quick look and they seem to be much more expensive now). Apparently you can hook up an IDE CD ROM drive on the secondary IDE channel though so I'd try that path, especially if you have one laying around already.
