A trigger event causes a restart.IEC/IEEE-bus command :SOUR:PHS:SEQ RETRThe PHS signal generation does not start until a triggerevent has occurred. The unit then automaticallyswitches over to the AUTO mode and can no longer betriggered.IEC/IEEE-bus command :SOUR:PHS:SEQ AAUTThe PHS signal generation does not start until a triggerevent has occurred. The unit then automaticallyswitches over to the RETRIG mode. Each new triggerevent causes a restart.IEC/IEEE-bus command :SOUR:PHS:SEQ ARETEXECUTETRIGGERTRIGGER...Executes a trigger even to start the PHS signal generation.IEC/IEEE-bus command :TRIG:DM:IMMOpens a window for selecting the trigger source, for configuring the triggeroutput signals and for setting the time delay of an external trigger signal.1125.5555.03 2.120E-9
