Default Re: Gate drive/ (r) 'scope measurements

Hey folks, i’m out and about, so please excuse the truncated replies.

Hugo: thank you ! that’s a radical solution and also a really comprehensive one. I’ll investigate with a view to buying such a scope. Your research paper is detailed as ever and I’ll take the time to read it more deeply. But your ingenuity and attention to details shines through, once again.

David: good call, thank you ! hadn’t thought of that specific pathway for current

Chris: thank you -

I’m not sure though how I can check the grounding of my bench power supply without opening it up.

Is the output socket marked ‘ground’ next to ’-ve’ likely to be connected to mains safety earth? Otherwise what is the possible configuration here?

Really interestingl comments on the limitations of some ‘scopes and the modules you mention look spot on.

I also like - and will emulate - the coax segment used to get clean readings

I’ll report back on due course , may be a while . It’s facinating stuff, if also sometimes a cause of a little frustration.

Thanks again folks
