Re: HP 5245L counting/gate problems
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
I just resurrected one.
If the power supply hasn't been re-capped, check the supply voltages first.? In my case every d*** capacitor was bad.? Check back then.

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

Re: 54003A success
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
