Digital Standard W-CDMA (NTT DoCoMo/ARIB 0.0)SMIQSET DEFAULTCHIP RATELINK DIRECTION/MULTIPLEXProvides the default setting for W-CDMA.For LINK DIRECTION/MULTIPLEX DOWN- in mode 8, channel 0 is a Perch channel, it is switched on and its symbolrate is 16 ksymbol/s- all other channels are also switched on (STATE ON), channel type (TYPE)is DPCH, symbol rate is 32 ksymbol/s- the channels have the same relative power (POWER)- the data are pseudo random (PN15), except for Perch channel, a data offsetof three times the channel number (3 • CHNO) is set.For LINK DIRECTION/MULTIPLEX UP- only channel 0 is switched on, channel type is DPCH, symbol rate is32 ksymbol/s- the data are pseudo random (PN15), no data offset is set.For LINK DIRECTION/MULTIPLEX UP_IQ_MULT- all channels are switched on except I-channel 0 in mode 8- Q-channel 0 is configured as DPCCH, all the other channels are configuredas DPDCH with a symbol rate of 16 ksymbol/s- all channels have the same relative power (POWER)- the data are pseudo random (PN15), no data offset is set.IEC/IEEE-bus:SOUR:WCDM:PRESSelection between 4.096 Mcps and 8.192 Mcps. Selecting 8.192 Mcpsdepends on the hardware configuration of the unit and is not offered yet.Selecting CHIP RATE has an effect on the generation of spreading codes andthus on the calculated chip sequence.IEC/IEEE-bus :SOUR: WCDM:CRAT R4MOpens a window for selecting the type of transmit signal from the differentmodes.DOWNUPUP_IQ_MULTActivates the generation of a downlink signal. In thismode, the transmit signal of a base station can begenerated in line with the Japanese ARIB standard oraccording to NTTDoCoMo specifications for anexperimental system.IEC/IEEE-bus :SOUR:WCDM:LINK DOWNActivates the generation of an uplink signal. In this mode,the transmit signal of a mobile station can be generatedin line with the NTTDoCoMo specifications for anexperimental system.IEC/IEEE-bus :SOUR:WCDM:LINK UPActivates the generation of an uplink signal with amultiplex mode for the I and Q channel. Separatechannel types and data sources are available for I andQ. In this mode, the transmit signal of a mobile stationcan be generated in line with the Japanese ARIBstandard.IEC/IEEE-bus :SOUR:WCDMA:LINK UPM1125.5555.03 2.156E-9
