PULSe The waveform shape is changed to the value set by
FUNCtion:TRIGgered for a duration determined by the pulse commands.
LIST The waveform shape is controlled by the waveform shape list when a
triggered transient occurs.

This command selects the shape of the output voltage waveform when a triggered step or pulse
transient occurs. The parameters are:
SINusoid A sinewave is output
SQUare A squarewave is output
CSINusoid The output is a clipped sine waveform. Both positive and negative peak
amplitudes are clipped at a value determined by
SOURce:FUNCtion:SHAPe:CSINusoid.
The output shape is described by one of the user-defined waveform
tables.
The maximum peak voltage that the AC source can output is 425 V peak. This includes any
combination of voltage and function shape values. Therefore, the maximum value that can be
programmed depends on the peak-to-rms ratio of the selected waveform. For a sinewave, the
maximum voltage that can be programmed is 300 V rms.
Note: You cannot program a voltage that produces a higher volt-second on the output than a
300V rms sinewave.

This command sets the clipping level when a clipped sine output waveform is selected. The
clipping characteristics can be specified in two ways:
The clipping level is expressed as a percentage of the peak amplitude at which clipping
occurs. The range is 1.33 to 100. These are the default units when the optional THD suffix is
not sent.
The clipping level is expressed at the percentage of total harmonic distortion in the output
voltage. The range is 0 to 43 percent. The optional THD suffix is sent to program in these
units.
