     Not riogorously, not, in my view, even approximately:
      V*I does not work with AC....
     Especially with complex wave forms, tho I'd think SSTC
     waveforms are less complex than others.
     A digitizing scope is one (the only?) thing that comes to
     mind...

     RF input, while interesting, ignores the losses in getting
     from DC, or power line AC, to 'rf'.
