Re: 8596E Spectrum Analyzer Fault
Not sure about 'autocouple' but the actual range seems to be irrelevant. I've tried several. It's the instant the 'stop' frequency is entered that brings on the fault, whether that be by keypad or

Re: HP 5245L counting/gate problems
You can use the old vintage cans and put a newer, low ESR capacitors inside to keep the vintage look.
Just make a simple pcb to solder the new cap inside and keep the old pins outside.

OK Scott, it has never been recapped as far as I know. I’ll look into how/where the supply voltages are tested and will probably just go ahead and recap to avoid any future supply

Re: HP 5245L counting/gate problems
Just an idea: In the case of the gate indicator (a neon bulb): try shining a bright light on it to see if that "fixes" it.
As for "not counting", I don't know an alternative other than to probe

Indeed, but with a 1000:1 probe that becomes a +/- 2000 volt input range which is sufficient.
That was a work requirement and their solution covers more, although this would be sufficient for them
