Trigger system consists of commands and configuration trigger mode
subsystems.
TRIGger
When the trigger system has been initiated, this command generates a trigger
signal regardless of the selected trigger source.
Command Syntax

Parameters
None
Examples
TRIG
Related Parameters
TRIG:SOUR TRIG:TIM
TRIGger:SOURce
This command selects the trigger source.
BUS Accepts a GPIB <GET> signal or a *TRG command as the trigger
source. This selection guarantees that all previous commands are complete
before the trigger occur.
EXTernal Selects the electronic load’s trigger input as the trigger source.
This trigger is processed as soon as it is received.
HOLD Only TRIG:IMM command will generate a HOLD mode trigger. All the
other trigger commands are not considered.
MANUal The event occurs when the Trig key is pressed.
TIMer The trigger will synchronize with the crystal within the electronic load.
Once the command is executed a synchronous oscillator will start running. Use
the TRIG: TIM to edit crystal cycle.
