Explanation
This command defines all compulsory parameter of a new multitone signal.
<No_Of_Bins_CHX> equals the total number of signal bins for channel 1 / 2.
<Bin_No_X_CHY> indicate the bin numbers as calculated with Equation 7 (p. 25).
<Phase_X_CHY> indicate the phases of the signal bins.
OUTPut[1-2]:LEVel <Level> <Unit>
