Basic Digital Operation (Option 651/652/654)Clipping a WaveformHow Power Peaks DevelopTo see how clipping reduces high power peaks, it is important to understand how the peaks developas you construct a signal.Multiple Channel SummingI/Q waveforms can be the summation of multiple channels, as shown in the following figure. If a bitin the same state (high or low) occurs simultaneously in several individual channel waveforms, anunusually high power peak (positive or negative) occurs in the summed waveform.Because the high and low states of the bits in channel waveforms are random and generally result ina cancelling effect, high power peaks occur infrequently with multiple channel summing.180 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
