For π/4 DQPSK modulation,a selection between Nyquist filters COS andSQRCOS or a user-defined filter USER (cf. SectionDigital Modulation) is possible.IEC/IEEE-bus :SOUR:DECT:FILT:TYPE COSTRIGGER MODE...FILTER PARAMETER Input value for the BT value for Gauss filtering or forthe roll-off factor for Nyquist filtering.IEC/IEEE-bus SOUR:DECT:FILT:PAR 0.51Opens a window for selecting the trigger mode.AUTOThe DECT signals are continuously transmitted in theactivated slots.IEC/IEEE-bus command SOUR:DECT:SEQ AUTORETRIGThe DECT signals are continuously transmitted in theactivated slots. A trigger event causes a restart. Thismode is not available if values different from zero areset for TIMING ADJUSTMENT or JITTERSIMULATION.IEC/IEEE-bus command :SOUR:DECT:SEQ RETRARMED_AUTO DECT 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:DECT:SEQ AAUTARMED_RETRIG DECT 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. This mode is not available ifvalues different from zero are set for TIMINGADJUSTMENT or JITTER SIMULATION.IEC/IEEE-bus command :SOUR:DECT:SEQ ARET1125.5555.03 2.323 E-9
