Figure 4-22 Clipped Sine Wave
The depth of clip is set using the crest factor or clip ratio. Each of them is defined by the
following expression. The clip ratio is set in percentage.
Crest factor = Peak value/RMS value
Clip ratio = Clipped sine wave peak value/Original sine wave peak value
As shown in
Table 4-8, the output voltage setting method differs depending on the clip depth setting method.
Therefore, a clip ratio less than 100% makes the output voltage smaller than the setting.
Table 4-8 Different Output Voltage Settings Depending on Clip Depth Setting Method
Clip Depth Setting Method Output Voltage Setting Method
Crest factor Sets the RMS of the clipped waveform
Clip ratio Sets the RMS of the sine wave before clipping

Notes
----------------------------------------------------------------------------------------------------------------
 When the clipped sine wave is output in the AC mode, the clip of the output waveform
may be tilted by the DC component remove function in the AC mode. To avoid this,
switch to the ACDC mode.
