Initiating the output trigger system
When the ac source is turned on, the trigger system is in the idle state. In this
state, the trigger system 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 ac source to receive triggers. To initiate for a
single triggered action, use:
INITiate:IMMediate:SEQuence1 or
INITiate:IMMediate: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
Selecting the output trigger source
The trigger system is waiting for a trigger signal in the Initiated state. Before you
generate a trigger, you must select a trigger source. To select the external Trigger
In BNC as the source, use:
TRIGger:SEQuence1:SOURce EXTernal or
TRIGger:TRANsient:SOURce EXTernal
To select GPIB bus triggers (group execute trigger, device trigger, or *TRG
command), use:
TRIGger:SEQuence1:SOURce BUS or
TRIGger:TRANsient:SOURce BUS
The SEQuence2 (or SYNChronize) trigger sequence does not have an INITiate
command. It is always initiated.
