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.
VOLTage:TRIGgered {|MAX|MIN|DEF}
CURRent:TRIGgered {|MAX|MIN|DEF}
POWer:TRIGgered {|MAX|MIN|DEF}
The user can choose to set all or any one of voltage, current, and power triggered
levels.
DEF (DEFault) means that when a trigger is received, no change will occur.
2. Specify a trigger signal source.
TRIGger: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
• IMM means the trigger source is the SCPI command INIT:IMM
• NONE means triggering is disabled. See , p. 109.
Auto
Sequencing
Auto Sequencing allows users to program a sequence of steps. Each step has the
properties of voltage, current, power limits, and OVP limit. The steps are either
programmed to run for a predetermined length of time or are programmed to pause
and wait for a trigger.
Programmed sequences can run one time only, or repeatedly up to 9999 times or
infinitely. You can store up to 10 sequences of 99 steps each. The duration of each
step may range from a minimum of 10 milliseconds to a maximum of 99 hours.

CAUTION
Setpoint limits do not apply to triggered setpoints.
