Basic Digital Operation (Option 651/652/654)Clipping a WaveformClipping a WaveformDigitally modulated signals with high power peaks can cause intermodulation distortion, resulting inspectral regrowth that can interfere with signals in adjacent frequency bands. The clipping functionenables you to reduce high power peaks by clipping the I and Q data to a selected percentage of itshighest peak, thereby reducing spectral regrowth.• How Power Peaks Develop on page 180• How Peaks Cause Spectral Regrowth on page 182• How Clipping Reduces Peak–to–Average Power on page 183• Configuring Circular Clipping on page 186• Configuring Rectangular Clipping on page 187Figure 8-8Clipping SoftkeysMode > Dual ARB > MoreAvailable only whenclipping type = |I|, |Q|For details on each key, use key helpas described on page 42.Agilent <strong>N5161A</strong>/<strong>62A</strong>/<strong>81A</strong>/<strong>82A</strong>/<strong>83A</strong> <strong>MXG</strong> <strong>Signal</strong> <strong>Generators</strong> User’s <strong>Guide</strong> 179
