SMIQEnhanced Functions For Digital Standard 3GPP W-CDMA (FDD)ADDITIONAL MSSTATESwitch with which up to 50 additional mobile stations can be added (ON) to a3GPP W-CDMA signal (defined in MS1 to MS4) otherwise all additional MSare deactivated (OFF).The additional MS are also calculated on the MCOD and added to the ARBmemory with the signal component of the primary MS.The basic settings of the additional mobile stations (e.g. Signature, AccessSlot, TFCI, FBI and TPC settings as well as the channel scenario fromPRACH, PCPCH, DPCCH + DPDCHs) are taken over from the primaryreference mobile station 4.In the OFF state, the following menu parameters have no influence on the3GPP W-CDMA signal:NUMBER OF ADDITIONAL MS,SCRAMBLING CODE STEP,POWER OFFSET [RELATIVE TO MS4].IEC/IEEE-bus command :SOUR:W3GP:MST:ADD:STAT ONNUMBER OFADDITIONAL MSSCRAMBLING CODESTEPPOWER OFFSETNumber of additional mobile stations 1 to 64.IEC/IEEE-bus command :SOUR:W3GP:MST:ADD:COUNT 33Initialization increment of uplink scrambling code generator for additional mobilestations. The scrambling code value of the primary reference MS4 is used as thebasic value of the scrambling code initialization of an additional MS.IEC/IEEE-bus command :SOUR:W3GP:MST:ADD:SCOD:STEP 5With this menu parameter it is possible to set a power offset of the activechannels of the additional MS relative to the powers of the active channels ofthe primary reference MS4.The resulting power value of the channel must be in the range from 0 to –60dB (limitation in case of underrange or overrange).IEC/IEEE-bus command :SOUR:W3GP:MST:ADD:POW:OFFS –3.01125.5555.03 2.261E-9
