Digital ModulationSMIQ(SOURCE... ) SOURCE... Opens a window for selecting the source formodulation data.EXT_PAR The modulation data are fed in via theparallel PAR DATA interface at the rearof SMIQ.IEC -bus :SOUR:DM:SOUR PAREXT_SER The modulation data are fed in seriallyat input DATA.IEC -bus :SOUR:DM:SOUR SERPATTERN A simple data pattern is continuouslygenerated.IEC-bus :SOUR:DM:SOUR PATTPRBS A pseudo random bit sequence isgenerated and continuously repeated.IEC -bus :SOUR:DM:SOUR PRBSSERDATA The modulation data are fed in via theasynchronous SER_DATA interface.IEC -bus :SOUR:DM:SOUR SDATDATA LIST Modulation data from listsIEC-bus :SOUR:DM:SOUR DLISPATTERNSelection of a simple data pattern which iscontinuously generated.0 0s are continuously generated.IEC -bus :SOUR:DM:PATT ZERO1 1s are continuously generated.IEC -bus :SOUR:DM:PATT ONE01 010 data changes are continuouslygenerated.IEC -bus :SOUR:DM:PATT ALTPRBS LENGTHSetting of PRBS generator length. 9 bit, 15 bit, 16 bit,20 bit, 21 bit and 23 bit can be selected. The periodof the data sequence is then between 2 9 -1 and 2 23 -1 bit (see Section 2.10.3 "Internal PRBS Data andPattern").IEC/IEEE-bus command :SOUR:DM:PRBS 15SELECT DATA LISTOpens a window for selecting a stored data list or forgenerating a new list.IEC/IEEE-bus :SOUR:DM:DLIS:SEL ´name´COPY CURRENTDATA LIST TOStores the current data list under a different name.IEC/IEEE-bus :SOUR:DM:DLIS:COPY ´name´DELETE DATA LISTDeletes a data list.1125.5555.03 2.102E-9
