The channel type can beseparately set for the I and Q channel.DPDCH Dedicated Physical Data Channel with data field DATADPCCH Dedicated Physical Control Channel with data field Pilot and TPCIEC/IEEE-bus command :SOUR:WCDM:CHAN4:I:TYPE DPCCOpens a window for selecting the symbol rate. The admissible selectiondepends on the channel type selected (TYPE). Possible values for DPDCHare 16, 32, 64, 128, 256, 512 and 1024 ksymbol/s ( ksymbols per second).The DPDCH type has a fixed symbol rate of 16 ksymbol/s.The symbol rate can be separately set for the I and Q channel.IEC/IEEE-bus command :SOUR:WCDM:CHAN4:I:SRAT D16Opens a window for the spread code settings. The first line of the windowindicates the code channel for which the settings are done (SPREADING OFCHANNEL NO).The long code settings are valid in common for the I and Q channel. For theshort code of I and Q separate settings are possible within a channel numberline.SHORT CODELONG CODE INITEntry value for the short code index.The upper limit depends on parameters CHIP RATE,SYMBOL RATE.IEC/IEEE :SOUR:WCDM:CHAN4:I:SCOD 9Entry value for initializing the long code generator inhexadecimal notation.IEC/IEEE :SOUR:WCDM:CHAN4:I:LCOD #H1LONG CODE OFFSET Entry value for a time shift of the long code withrespect to the data symbols in units of chip duration.IEC/IEEE :SOUR:WCDM:CHAN4:I:LCOD:OFFS 51125.5555.03 2.166E-9
