[SOURce:]FUNCtion
The [SOURce:]FUNCtion subsystem controls what waveform shape (arbitrary,
sinusoid, etc.) the Agilent E1445A generates. For arbitrary waveforms generation,
the subsystem controls which of the 128 possible segment sequences are selected.

Comments • The <shape> parameter values are shown as follows:
– DC: Generates a DC output voltage.
– RAMP: Generates a stepped ramp. The [SOURce:]RAMP subsystem controls the
polarity and number of points.
– SINusoid: Generates a sinusoidal voltage. SINusoid requires that
TRIGger[:STARt]:SOURce INTernal1 be selected.
– SQUare: Generates a square wave. The [SOURce:]RAMP:POLarity command
controls the polarity.
– TRIangle: Generates a stepped triangle wave. The [SOURce:]RAMP subsystem
controls the polarity and number of points.
– USER: Generates an arbitrary waveform. The [SOURce:]FUNCtion:USER
command selects the segment sequence to be generated.
• For the DC function: The voltage level is specified by
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude].
• For the RAMP, SINusoid, SQUare, TRIangle, and USER functions:
– Use [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] to set output
amplitude. For arbitrary (
USER) waveforms, this command specifies the
full-scale output voltage.
– [SOURce:]VOLTage[:LEVel][:IMMediate]:OFFSet specifies the offset voltage.
