DPDScale is average rms voltage of PA_Out waveform when extracting DPD model
coefficients and can be used with 3 steps:
1.
Calculate rms voltage ratio of PA_Out waveform to PA_In waveform which is
normalized
2.
Apply ratio got from step 1 on normalized PA_In waveform by multiplying
calculation
3.
Apply DPD model coefficients on waveform got from step 2 to get pre-distorted
waveform which then to be normalized before downloading to signal generator
