:TRIGger[:SEQuence]:SOURce
Syntax :TRIGger[:SEQuence]:SOURce {BUS|IMM}
:TRIGger[:SEQuence]:SOURce?
Description Select the trigger source.
Query the trigger source currently selected.
Parameter Name Type Range Default
{BUS|IMM} Discrete BUS|IMM BUS
Explanation  The trigger sources include BUS (bus trigger) and IMM (immediate trigger). In
bus trigger, also called software trigger, the power supply receives trigger from
the bus, namely the power supply receives trigger via software. In immediate
trigger, the power supply receives immediate trigger via the remote interface.
 When the trigger source is set to "IMM" (immediate trigger), the system
executes a complete trigger operation (the voltage/current of the specified
channel changes to the trigger voltage/current currently set immediately)
immediately after executing the :INITiate or :TRIGger:IN:IMMEdiate
command and there is no delay.
 When the trigger source is set to "BUS" (bus trigger, namely software trigger),
the system generates a trigger by executing the *TRG command after
executing the :INITiate or :TRIGger:IN:IMMEdiate command to initialize the
trigger system. Then, the power supply executes a trigger operation (the
voltage/current of the specified channel change to the trigger voltage/current
currently set) after the specified delay time (if the delay time is
set, :TRIGger[:SEQuence]:DELay ).
 When the trigger source is set to "BUS" (bus trigger, namely software trigger),
the *WAI command can ensure the synchronization. After executing the *WAI
command, the power supply will only execute new command when all the
pending operations are completed.
 When the trigger source is set to "BUS" (bus trigger, namely software trigger),
you can use the *OPC command to report that the operation is completed. The
*OPC? command will return "1" to the output buffer and the *OPC command
will set the bit0 (OPC bit, operation complete) in the standard event register
when the operation is finished.
 You can also send the :TRIGger:IN:CHTYpe command to select the trigger
source type.
Return Format The query returns BUS or IMM.
Example :TRIG:SOUR BUS /*Set the trigger source to BUS (bus trigger, namely software
trigger)*/
:TRIG:SOUR? /*Query the trigger source currently selected and the query
returns BUS*/
