Trigger Tutorial
The RPS trigger system is a flexible, multi-purpose system that controls the operation of the
instrument to suit a variety of user-defined applications. The trigger diagram below provides a
graphical view of how the trigger sources and destinations are interconnected.

Trigger Sources
The following table describes the available trigger sources, which are shown on the left of the trigger
diagram. Not all trigger sources can be applied to every trigger subsystem.
Source Description
BUS Enables GPIB device triggers, *TRG, or <GET> (Group ExecuteTrigger).
CURR1 Selects an output current level.
IMMediate Triggers the transient as soon as it is INITiated.
PIN<n>|EXTernal Selects a digital port pin configured as a trigger input. <n> specifies the pin number. EXTernal selects ALL con-
nector pins that have been configured as trigger inputs.
TRAN1 Selects the transient system as the trigger source.
TRIG:ACQ:IMM Triggers the acquisition immediately.
TRIG:TRAN:IMM Triggers the transient immediately.
VOLT1 Selects an output voltage level.
Trigger Destinations
The following table describes the trigger system destinations.
Destination Description
Digital pin Sends the trigger to the designated digital pin. See Programming the Digital Port.
Transient system Sends the trigger to the designated transient (STEP, BOST, EOST)
Acquisition system Sends the trigger to the acquisition system (TOUT)
Arb Starts the arbitrary waveform. Notethatthe waveform must first be enabled and initiated. SeeProgramming
Output Transients.
