What I’ve want to know is;

1. Current measurent with high accuracy up to let’s say 100MHz with moderate accuracy was possible when attached to the input of DSO?

2. Is there current probe provides a truly displayed a real current waveform so if I use multi trace oscilloscope use for voltage measurement simultaneously? So I expect in this way I could observe current and voltage waveform relationship at the same time when observing a complex electrical waveform?

3. If point 2 above satisfied, can I have to do some mathematical operation upon two waveforms by multiplying them together (trace A x trace B) so the resultant trace represent instantaneous power (Watts)?

Thanks and Regards
