Digital Standard 3GPP W-CDMA (FDD)SMIQParameters that are valid for the current base station:BS 1(2,3,4) STATE ON The BS is active. All other parameters are activated.IEC/IEEE-bus command :SOUR:W3GP:BST1:STAT ONOFF The BS is inactive. The other parameters are ignored.IEC/IEEE-bus command :SOUR:W3GP:BST2:STAT OFFSCRAMBLING CODESTATEONOFFThe scrambling code is active.IEC/IEEE-bus :SOUR:W3GP:BST1:SCOD:STAT ONThe scrambling code is inactive (test mode).IEC/IEEE-bus :SOUR:W3GP:BST2:SCOD:STAT OFFSCRAMBLING CODE Code of base station. At the same time, the initial value for the scrambling codegenerator. Permissible values are in the range 0 to 0x5FFF.IEC/IEEE-bus command :SOUR:W3GP:BST1:SCOD #H1TFCI STATE ON TFCI field is used in the frame.IEC/IEEE-bus command :SOUR:W3GP:BST1:TFCI:STAT ONOFF TFCI field is not used in the frame.IEC/IEEE-bus command :SOUR:W3GP:BST2:TFCI:STAT OFFTFCI (DPCH)Setting the TFCI value in the range 0 to 1023. A combination of 30 bits isselected by this value. This combination is distributed over 15 successive slotsin groups of two.IEC/IEEE-bus command :SOUR:W3GP:BST4:TFCI 212 ND SEARCH CODEGROUPTPC PATTERN READOUT MODEThis parameter indexes the “Allocation of SSCs for secondary SCH“ tabledescribed in the 3GPP standard, reference [2], Table 9. For each slot in theframe, this table assigns a certain spreading code to the synchronization codesymbol. The parameter’s range is 0 to 63. This parameter can only be read.The value is calculated from the SCRAMBLING CODE.IEC/IEEE-bus command :SOUR:W3GP:BST3:SSCG?TPC bits are used for W-CDMA to inform the called station if the transmitpower is being increased or decreased. The contents of the TPC field can beseparately defined in this panel in the table below for the channels of the BS.The parameter TPC Pattern Read Out Mode is used to define how this bitpattern is to be used. The following modes are distinguished:• Continuous: A bit is taken for each slot from the up to 24-bit long bitpattern for the Transmitter Power Control field of the slots and entered inthe bit stream several times (depending on the symbol rate). The specifiedbit pattern is used cyclically.• Single + All 0: A bit is taken for each slot from the up to 24-bit long bitpattern for the Transmitter Power Control field of the slots and entered thebit stream several times (depending on the symbol rate). The specified bitpattern is used once, then the TPC sequence is continued with 0 bits.• Single + All 1: A bit is taken for each slot from the max. 24-bit long bitpattern for the Transmitter Power Control field of the slots and entered inthe bit stream several times (depending on the symbol rate. The specifiedbit pattern is used once, then the TPC sequence is continued with 1 bits.1125.5555.03 2.194E-9
