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.
