You should now see a display that is similar to the one shown in Figure 8-8 . The CCDF plot displays the
peak to average characteristics of the waveform with randomly generated phases and a random seed.
The random phase setup simulates the typically random nature of multitone waveforms. Notice that
randomly distributed phases result in a much lower peak to average ratio than fixed phases. An increase
in the number of tones with random phases will decrease the probability of a maximum peak power
occurrence.
