Nick, It is confusing, and above my pay grade! Could the 8(etc)ma be measured at the center of the waveform (dv/dt). Since its a square wave there is power in the harmonics too that will cause calcula

Just one more data point for this discussion. I experimented with different oscillators for IMD measurements of wideband amplifiers (so the 2 frequencies are far apart, for example 3 and 4MHz). Si5351

I think it's called DSPVIEW
