Hello Alan, this sought of conundrum normally does my head in, I would guess the true test is to ensure the source and the load are correctly matched in impedance terms and then do the measurement, not to sure how accurate the Avo 8 is over a given frequency range, mines got a definate peak and roll off but can't remember the details, if the source and the load are correctly matched then maybe try measuring the peak input with a scope and work out the RMS from that and thus the power in from the resultant.
