1) I have doubt how actually the power measurement equation, Pmeas=(2*Vcom*(V1-V0)+V0^2-V1^2)/(4*R*CF*Ms) has been derive from instrument fundamental or design charactheristic. I manage to get the result of measurments, just want to know further how this equation been derived.

2) Do I need to put into equation for CF let say 99.2% at 50 MHz (from sensors 478A) while I have done and "ON" table edit CF & frequency accordingly on the N432A power meter? Or do I need select either one as 100%? I affraid the CF let say 99.2% become redundance..
