Re: Feet for HP8672A
Sure ¡ª injection molded parts are great, but the quality of those feet, when 3D-printed out of something strong like polycarbonate on a reasonably priced printer (~$750 range) would be entirely

Re: Feet for HP8672A
As far as I can tell those are pretty standard HP feet that are abundant on ePay in any colors. I seriously doubt 3D-printed ones would be any cheaper not even mentioning their poor quality, not even

You can make your own with a 3D printer. ?Check your local Public Library - they may have free access to a 3D printer. 73, Bernie, VE3FWF

Re: HP 6012B volt zero and current regulation
I made a constant current load at work, 100 amps 200 volts, of course with a control loop.? When first connected the loop is calling for max current and it made a big current spike.? As this was

Re: HP 6012B volt zero and current regulation
One that doesnt give spikes :-)) Any supply with feedback linear or switcher is a potential spike producer ! I am not up to date in this area it is possible that slow-start supplies might be best.

Re: HP 6012B volt zero and current regulation
Hi Dave. I got to thinking a bit about the point Alan made below, and it's a very good one. If you consider the turn-on behavior of an unregulated linear supply (i.e. the classic transformer, bridge

Re: HP 6012B volt zero and current regulation
OK, I'll bite-- What kind of power supply would you recommend?? I always thought that a regulated supply would be the safest. Were these linear or switcher supplies that produced the spikes? Thanks,

Re: 8566B SA all PLLs unlocked
I too have seen a failed power resistor. ?Other failed item maybe be a leaky diode that then shuts down the power supply. ?If the -40v supply is other than 0, -40v suspect a leaky diode, or shorted
