Re: Keysight Forum
At least in its current state, "AI" is a poor substitute for the real thing. I was looking for a 20W 50 ohm attenuator the other day and the text associated with them read like a dictionary

Re: HP 54512B (pair) repair
Thanks, Jim. I still have to perform that test where I play The Cure from my garage with the door open, which I'm sure you'd hear from your bench!! ;)))) I tried to pry off the battery this morning

I would like a copy! After I saw Dave Feldman's request, I went through my 8660x documents yesterday and the 11707A is the only one for which I have the instrument but not the manual. I's even borrow

Free: Repaired 6GHz coupler for 8753D/E or 85047A
Do you need a coupler to fix your network analyzer? I have a repaired 5087-6007 coupler which should fit the 8753D, E, ES or ET or the 85047A test set. It was presumably blown out with applied RF
