3 - Programming the DC Source

Initiating the Output Trigger System
When the dc source is turned on, the trigger subsystem is in the idle state. In this state, the trigger
subsystem ignores all triggers. Sending the following commands at any time returns the trigger system to
the Idle state:
ABORt
*RST
*RCL
The INITiate commands move the trigger system from the Idle state to the Initiated state. This enables
the dc source to receive triggers. To initiate for a single triggered action, use:
INITiate:SEQuence1or
INITiate:NAME TRANsient
After a trigger is received and the action completes, the trigger system will return to the Idle state. Thus it
will be necessary to initiate the system each time a triggered action is desired.
To keep a trigger system initiated for multiple actions without having to send an initiate command for each
trigger, use:
INITiate:CONTinuous:SEQuence1 ON or
INITiate:CONTinuous:NAME TRANsient, ON
Generating Triggers
You can only program output triggers over the GPIB bus. Since BUS is the only trigger source for output
triggers, the following command is provided for completeness only:
TRIGger:SOURce BUS
After you have specified the appropriate trigger source, you can generate triggers as follows:
Single Triggers Send one of the following commands over the GPIB:
TRIGger:IMMediate
*TRG
a group execute trigger
Continuous Triggers Send the following command over the GPIB:
INITiate:CONTinuous:SEQuence1 ON
When the trigger system enters the Output Change state upon receipt of a trigger (see figure 3-1), the
triggered functions are set to their programmed trigger levels. When the triggered actions are completed,
the trigger system returns to the Idle state.
