what ever does the clamp, if bellow 32kHz, the power meter catch it and compute the real power.
modern powermeter (and even old analog like the one I used in the 80s) don't care of the shape of the signal. it make the integral of the U*I product over time... only problem is bandwidth, high and low. 2013/5/28 Andrew <andrew...@att.net> > ** > I also am pretty sure that most here haven't understood Duncan's "diode > fudge".
