It is a Tektronix 420a ps failed. Threw it away: transformer costs more than a news Silgent 2000X
it WAS a high tech switching powersupply with like 4 voltages out (6 or 8 if +- included).
I realize this project might "be back shelf" (not the easiest project for a hobbiest to finish in near term).
I have a used Tek 420a with working PS (dead acquisition board) to work with.
Can I just disconnect and measure the PS with a 50Mhz scope and mimic the results? With a few drawdown tests?
Can I just buy four chinese switching modules (one for each V needed) ($12 ea, say) then "make my build all about cleaning up the signal" so it "looks as good as the other" on the 50Mhz scope? (all four would fit in the 420a easily I think)
Not asking for total instructions. just broad warnings to save me allot of time, if such advice is possible. If my thinking is way out of the ball field.
I'm a little familiar with power supply jargon - but totally unfamiliar with "what is sufficient to prevent frying IC". (signal smoothness, maximum drawdown allowed).
I've tried to find lessons on the internet about "what signal clean-ness is required" and "what drawdown is acceptable" for IC chips. I can't find any after long google searches. Obviously it would be too big a job to chart every chip's requirements with no schematics ever released. I need something "more in general".
(tek 420a mess of a board that "supported all voltages on one 5 layer board not separately but intertwined" (making repair quite awful. i guess that's high tech!)
