I am interested to know how members go about probing relevant nodes in power electronic circuits. Conventional scope probes suffer from very long ground leads which pick up a lot of noise and add a lot of inductance to the path.
I recall a technical article on here about placing SMA connectors on the PCB and then using an SMA to BNC adaptor to plug that straight into the scope. I was rather nervous about this as the lead won't have the 10x attenuation and I don't want to blow up the input of my scope.
I have also tried the ordinary little through-hole test loops which are very convenient for DC signals and low frequency stuff but again you're stuck with a conventional probe and long ground leads.
