Triggering
Commands
Triggers are event-driven signals that instruct power supplies to change their output.
Triggering provides a method to control changes in the power supply’s output and to
program several power supplies to react at the same time. Triggering is useful in
manufacturing processes where power requirements change as the machinery
performs different operations.
To program triggers:
1. Configure the desired output levels as a result of a trigger.
:VOLT:TRIG {<voltage>|MAX|MIN|DEF}
:CURR:TRIG {<current>|MAX|MIN|DEF}
The user can choose to set both or just one of voltage or current triggered levels.
DEF (DEFault) means that when a trigger is received, no change will occur.
2. Specify a trigger signal source.
TRIG:SOURce {BUS|EXT|IMM|NONE}
Where:
• BUS
means the trigger source is the IEEE 488.1 GET or “*TRG”
• EXT
means the source is the external trigger line. See “User Lines” on page
40
• IMM
means the trigger source is the SCPI command INIT:IMM
• NONE
means triggering is disabled.

CAUTION
Setpoint limits do not apply to triggered setpoints.
