Hi all!

I'm looking for a service manual for the HP pulse generator 8133A.
Can someone help out?

Did you ever find a schematic for this instrument?

Yes, it's easy:

1) go to http://www.ko4bb.com/getsimple/index.php?id=manuals
2) type 8133A into search box (it's not listed in the directory)
3) have fun (and tell me where to get a cheap 8133A)

Ah, I looked through the directory but didn't realize there are unlisted documents, including an 8133A service guide!  Excellent!

Well, I bought one as a project to see if I can fix it up... No idea what inside the case, or even if it's board complete, but the seller accepted what I thought was a reasonable offer so I'll take a look.  This is the one I bought: https://www.ebay.com/itm/232976283208
Will try to arrange to go pick it up tomorrow.

It COULD be easy to fix.  Could also have had boards pilfered and I'm stuck with a bad power supply and broken front panel and nothing else.  I guess I'll find out.

Without a service manual available I wouldn't have bothered...

Wow, this is a monster... built like the proverbial brick outhouse.  It must weigh 60 lbs at least.  So, picked up the 8133A, got home and powered it up to see what happens, if there are any beeps, POST messages, fans come on, whether it responds to GPIB, etc.

It comes on.  I poke around a bit.  It works fine.  Checked some low frequency stuff with the scope.  Will check 1-3GHz output with the counter.  Perhaps it has some problems with certain kinds of outputs or something.  Keyboard seems okay, not too snaggly.



So I'm leaving it running for a few hours to see if it has any thermal issues.  Then will open it up and give it a good cleaning, check caps, etc.  I bet it either had a loose connector that resettled during transport (or because I stood it up sideways perhaps) or some other trivial problem.

Well, that has worked out alright so far.
