SMIQDigital ModulationTRIGGER MODESelection of trigger mode.This selection is only available when option SMIQB11 is installed.AUTORETRIGARMED_AUTOARMED_RETRIGSINGLEThe data sequences from the selected DATA LIST andCONTROL LIST are continuously repeated.IEC/IEEE-bus command :SOUR:DM:SEQ AUTOThe data sequences are continuously repeated. A triggerevent causes a restart from symbol 1.IEC/IEEE-bus command :SOUR:DM:SEQ RETRA start of data sequences from symbol 1 is caused by atrigger event. The unit is then automatically set to AUTOand can no longer be triggered.IEC/IEEE-bus command :SOUR:DM:SEQ AAUTA start of data sequences from symbol 1 is only caused bya trigger event. The unit is then automatically set toRETRIG. Each new trigger event causes a restart of thedata sequences.IEC/IEEE-bus command :SOUR:DM:SEQ ARETA trigger event causes a single data sequence run.IEC/IEEE-bus command :SOUR:DM:SEQ SINGEXECUTETRIGGERTRIGGER...Executes a trigger event to start a data sequence.IEC/IEEE-bus command :TRIG:DM:IMMOpens a window for setting the different types of trigger and for setting thetime delay of the trigger signal.
