:TRIGger[:SEQuence]:SINGle
Description
Generates a trigger regardless of the trigger source selection. The command is implemented as an overlapped command and it is not completed until the measurement has ended. Thereforethe end of the command CAN be awaited with an OPC command.
If the trigger is NOT in the Waiting for Trigger state, the command has no effect and a Trigger Ignored error (nr. -211) is generated. The only difference between this command and the [:TRIGger[:SEQuence][:IMMediate]](xref:sequenceImmediate) is that this command CAN be awaited and the [:TRIGger[:SEQuence][:IMMediate]](xref:sequenceImmediate) command CAN NOT be awaited.
For more information about the trigger system, please refer to Trigger System.
