[SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPLitude] {<voltage>[MIN|MAX}
This command programs the pending triggered voltage level of the power supply, which is a stored value and transferred to
the output terminals when a trigger occurs. A pending triggered level is not affected by subsequent VOLTage commands.
[SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPLitude]? [MIN|MAX]
This query checks and returns the presently programmed triggered voltage level. If no triggered level is programmed, the
VOLTage value is returned.
VOLTage:TRIGgered? Return the VOLTage value or the set triggered voltage level of the selected output
VOLTage:TRIGgered? MAX Return the maximum programmable voltage values of the selected output
VOLTage:TRIGgered? MIN Return the minimum programmable voltage values of the selected output
4.25 Trigger Source Choice
The power supply’s system allows a change in the output of the power supply when receiving a trigger. Triggering the power
supply includes internal immediate trigger and bus trigger.
Triggering the power supply is a multi-step process:
1. Select an output with the INST:[SELect] command and then configure the power supply for the triggered output level by
using CURRent:TRIGgered and VOLTage:TRIGgered.
2. Specify the source from which the power supply will accept the trigger. The power supply will accept a bus (software)
trigger or an immediate trigger.
3. Set the time delay between the detection of the trigger on the specified trigger source and the start of any corresponding
output change. Notice that the time delay is valid for only the bus trigger source.
4. Execute an INITiate[:IMMediate] command. If the IMMediate source is selected, the selected output is set to the
triggered level immediately. But if the trigger source is the bus, the power supply is set to the triggered level after
receiving the Group Execute Trigger (GET) or *TRG command.
4.26 Selecting a Trigger Source
You must specify the source from which the power supply will accept a trigger. The trigger is stored in volatile memory; the
source is set to bus when the power supply has been off or after a remote interface reset.
4.27 Bus (Software) Triggering
1. Select the bus trigger source by sending the following command.
TRIGger:SOURce BUS
2. Trigger the power supply from the remote interface by sending the *TRG command. And the power supply outputs
specified triggered output level after the set time delay if any delay is given.
3. You can also select the trigger source from the RS232 or GPIB interface. The operation has been introduced before.
4.28 Immediate Triggering
1. Select the internal immediate trigger source by sending the following command:
TRIGger:SOURce IMM
2. If the IMMediate source is selected as a trigger source, once the trigger command is executed, the power supply outputs
triggered output voltage and current immediately. Any delay is ignored.
