Source Subsystem (Function)
This subsystem programs the output function of the ac source.
Subsystem Syntax
[SOURce:]
FUNCtion
[:SHAPe]
[:IMMediate] <shape> Sets the periodic waveform shape (SIN | SQU | CSIN | <user>)
:MODE <mode> Sets the waveform shape mode (FIX | STEP | PULS | LIST)
:TRIGgered <shape> Sets the triggered transient shape (SIN | SQU | CSIN | <table>)
:CSINusoid <n> [THD] Sets the % of peak at which the sinewave 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 sinewave. Both positive and negative peak amplitudes are clipped
at a value determined by the FUNCtion:CSINusoid command.
<table>
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, voltage offset, 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: For Agilent models 6814B, 6834B and 6843A, you cannot program a voltage that
produces a higher volt-second on the output than a 300 Vrms sinewave.
