Enable the output transient function
First, you must enable the output to respond to transient triggers. Unless an output transient function
enabled, nothing will happen even if you have programmed the transient parameters and generated a
transient trigger.
Front Panel Menu Reference SCPI Command
Select Transient\Mode .
If you are operating in voltage priority mode select
Voltage mode. If you are operating in current priority
mode select Current mode.
In the dropdown list, select Step, List or Arb
transients. Then press
Select .
To enable the transient function, use:
VOLT:MODE STEP
VOLT:MODE LIST
VOLT:MODE:ARB
or
CURR:MODE STEP
CURR:MODE:LIST
CURR:MODE:ARB
In Step mode, the triggered value becomes the immediate value when the trigger is
received. In Fixed mode, trigger signals are ignored; the immediate values remain in
effect when a trigger is received.
Program the transient parameters
For example, set the triggered voltage level if you are programming a voltage step:
Front Panel Menu Reference SCPI Command
Select Transient\Step .
Select the Trig Voltage box to set the voltage. Enter
a value and press Select.
To set a voltage step level of 15 V use:
VOLT:TRIG 15
Select the trigger source
A TRIGger:TRANsient[:IMMediate] command over the bus will always generate an
immediate transient trigger, regardless of the selected trigger source.
Unless you are using the front panel menu or a TRIGger:TRANsient[:IMMediate] command to trigger
the transient, select a trigger source from the following:
Trigger Source Description
Bus Selects GPIB device trigger, *TRG, or <GET> (Group Execute Trigger).
External Selects ANY pin that has been configured as a Trigger Input on the digital control port.
Immediate Triggers the transient as soon as it is INITiated.
Pin<1-7> Selects a specific pin<n> that is configured as a Trigger Input on the digital control port.
Use the following commands to select a trigger source:
