1 = Termination and input impedance of the circuit board
2 = Voltage level measured at the circuit board
3 = Signal characteristics of the DC Modulator
4 = Signal characteristics at the inputs of the PA (see the documentation of the PA, for example its data
sheet)
The dialog displays a block diagram with parameters, necessary to configure the
envelope signal.
