Triggering Commands

•You can also trigger the power supply from the GPIB interface by sending the IEEE-488 Group Execute Trigger (GET) message. The following statement shows how to send a GET from a Agilent Technologies controller.

TRIGGER 705 (group execute trigger)

•To ensure synchronization when the bus source is selected, send the *WAI (wait) command. When the *WAI command is executed, the power supply waits for all pending operations to complete before executing any additional commands. For example, the following command string guarantees that the first trigger is accepted and is executed before the second trigger is recognized.

TRIG:SOUR BUS;*TRG;*WAI;*TRG;*WAI

•You can use the *OPC? (operation complete query) command or the *OPC (operation complete) command to signal when the operation is complete. The *OPC? command returns ‘‘1’’ to the output buffer when the operation is complete. The *OPC command sets the ‘‘OPC’’ bit (bit 0) in the Standard Event register when the operation is complete.

Immediate Triggering

•To select the immediate trigger source, send the following command.

TRIG:SOUR IMM

•When the IMMediate is selected as a trigger source, an INITiate command immediately transfers the VOLT:TRIG or CURR:TRIG value to VOLT or CURR value. Any delay is ignored.
