Yup. Thank you, sounds vaguely familiar. There is ofcourse a small problem....
Planning to use this DC/DC converter to feed:
1: isolation amplifier, low voltage(immediate need is <60V, really would not mind to build final version to survive three phase 400 VAC), low frequency (isolation amplifiers are not fast) AMC1200 + some pre amplifier - which I haven't fiqured out yet.
2: small signal (TTL and such) differential amplifier. Nothing too fancy, my scope is 50 MHz. Video amplifier should do. There are many designs, some very ambitious and very involved.
There are some hurdles to overcome...some are very trivial to those who are in the know, but I'm fighting to understand.
Right now I am in PSU rippel measurement/definition phase.
Next thing is to figure out how to transfer that signal to scope. For low frequency righ now shielded and twisted pair cable, maybe even ethernet cat5e cable looks pretty good. Traditional 50 ohm transmission line feels safe, but my scope is that basic - it does not even have internal 50 ohm termination.
If I need passive probe, I'll buy it. I wish there were cheap 1:5 or 1:10 ready made compact scope probe for 0,1" square test pins - maybe I need to buy cheap one and bucher one to fit a pinheader.
