Re: N9020A
One part of the analyser is merely a computer doing signal analysis in SW, displaying measurements, doing automation etc. Not sure about the architecture of these "modern" instruments, but I guess

Re: Interesting power supply issue!
Hi Peter, maybe there is a short circuit in the PS towards its chassis that only reveals itself when screwed to the instrument's chassis? cheers Martin

Re: N9020A
The X-series analyzers have evolved quite a bit since their introduction, as the early versions ran XP, and the newer ones are probably on Win10, maybe 11. That gets into licensing negotiations with

HP 140B LVPS -12.6V Not Working
I was working on my HP 140B when I suddenly smelled something overheating. I looked and I'd lost the traces and on further inspection, both -100V and -12.6V were gone. -100V was an open 1/2A fuse and

Interesting power supply issue!
I have an 8711B where the power supply runs when out of the chassis but when plugged in it keeps trying to start as if there is a short. I have determined that the supply acts this way when the small

Re: Re-capping an HP-130 Scopes
You won't be able to set up the power supplies by themselves, the other rails depend on the -150V rail, which has the voltage reference tube. Pulling the 6AQ5 (V17 in the pdf manual) would be enough
