If you are using lists or arbs to generate sinusoids near the grid frequency, there will
be additional distortion currents in the line. Refer to the
section.
The output of the Keysight RPS models can be modulated by the instrument's built-in arbitrary
waveform generator. This allows the output to generate complex user-defined voltage or current
waveforms. The following are key features of the constant-dwell arbitrary waveform generator:
Generate voltage or current arbitrary waveforms.

Arbs can contain up to 65,535 data points.

A single dwell value applies to every point in the constant-dwell arbitrary waveform (see

ARB:VOLT:CDW:DWEL
Only the Arb that corresponds to the active priority mode, either voltage or current priority, may be

generated.
Specify the Arb type and dwell
To specify the Arb type and dwell:
Front Panel Menu Reference
Select Transient\Arb\Config.
In the dropdown list, pick either a voltage or a current
Arb. Then press Select.
Enter a dwell value in the Dwell field. Then press
Select.
Configure the Arb
Note that you can only view Arb point data from the front panel. You cannot program Arb data from the
front panel. You must use the SCPI ARB:CURRent:CDWell or ARB:VOLTage:CDWell commands to
program the Arb data.

for dwell information).
To specify a voltage or current Arb:
ARB:FUNC:TYPE VOLT
ARB:FUNC:TYPE CURR
To specify a dwell time of 1 millisecond:
ARB:VOLT:CDW:DWEL 0.001
ARB:CURR:CDW:DWEL 0.001
