Note: The AC source output remains at the last programmed values at the completion of
the list.
In three-phase mode, the voltage lists are phase selectable. You can set up a different voltage
list for each phase. To do this, use the PHASE key to choose the desired phase, as described in
the example. Note that fields common to all phases such as DURATION, END DELAY and
REPEAT always apply to all three phases in three-phase mode. When the cursor is moved to
any of these fields, the phase enunciator in the top right-hand corner always reverts to øABC.
Frequency transients are identical to voltage transients except they apply to all three phases at
all times in a three-phase configuration.
4.7.6 Programming Slew Rates
As shown in the previous examples there are a number of ways that you can generate custom
waveforms. Programmable slew rates provide additional flexibility when customizing waveforms.
Slew rates determine how fast the voltage or frequency is changed by the controller when a step,
pulse, or list transient is triggered. Slew rates cannot be programmed from the front panel and
are always set to their maximum values at power on. To use programmable slew rates, the AC
source must be programmed over the bus. Refer to the SCPI Programming Manual for more
information about programming slew rates.
