98 i Series / iX Series

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 annunciator 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.
