Digital Standard GSM/EDGESMIQ(MODULATION...)The following parameters are used with GSMMODULATION TYPEFSK DEVIATIONFILTER TYPEFILTER PARAMETEROpens a window for selection of the modulation type.GMSK Gaussian Minimum Shift KeyingGFSK Gaussian filtered Frequency Shift KeyingIEC/IEEE-bus SOUR:GSM:FORMat GMSKInput value of deviation with GFSK selected.With GMSK selected, the deviation is fixed to thefourth part of the symbol rate.IEC/IEEE-bus SOUR:GSM:FSK:DEV 67 KHZDisplay of the baseband filter for GSM.Input value for the B×T value (Gaussian filter).IEC/IEEE-bus SOUR:GSM:FILT:PAR 0.31The following parameters are used with EDGEMODULATION TYPEFILTER TYPEThe modulation type for EDGE is displayed. It ispermanently set to 8PSK EDGE. In contrast to themodulation types for GSM, the one for EDGE hasthree bits per symbol.The filter for EDGE is displayed. It is permanently setto GAUSS LINEAR.TRIGGER MODE...Opens a window for selecting the trigger mode.AUTOThe GSM signals are continuously transmitted in theactivated slots.IEC/IEEE-bus command SOUR:GSM:SEQ AUTORETRIGARMED_AUTOARMED_RETRIGThe GSM signals are continuously transmitted in theactivated slots. A trigger event causes a restart.IEC/IEEE-bus command SOUR:GSM:SEQ RETRThe GSM signal generation does not start until atrigger event has occurred. The unit thenautomatically switches over to the AUTO mode andcan no longer be triggered.IEC/IEEE-bus command SOUR:GSM:SEQ AAUTThe GSM signal generation does not start until atrigger event has occurred. The unit thenautomatically switches over to the RETRIG mode.Each new trigger event causes a restart.IEC/IEEE-bus command SOUR:GSM:SEQ ARET1125.5555.03 2.306 E-9
