4.18 Source Subsystem - Function
This subsystem programs the output function of the AC source.
Subsystem Syntax
[SOURce:]
FUNCtion
[:SHAPe]
[:IMMediate] Sets the periodic waveform shape
(SIN|SQU|CSIN|)
:MODE Sets the waveform shape mode (FIX|STEP|PULS|LIST)
:TRIGgered Sets the triggered transient shape
(SIN|SQU|CSIN|)
:CSINusoid [THD] Sets the % of peak at which the clipped sine clips (or %
THD)
FUNCtion
This command selects the shape of the output voltage waveform as follows:
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 the
SOURce:FUNCtion:SHAPe:CSINusoid setting.
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.
Before programming a different waveform shape, the output voltage should be programmed to
zero volts. After the shape is changed, the voltage maybe programmed to the desired value.
Note: You cannot program a voltage that produces a higher volt-second on the output than a
300V rms sinewave.

FUNCtion:MODE
This command determines how the waveform shape is controlled during a triggered output
transient. The choices are:
FIXed The waveform shape is unaffected by a triggered output transient.
STEP The waveform shape is programmed to the value set by
FUNCtion:TRIGgered when a triggered transient occurs.
