SMIQ SOURce:WCDMa Subsystem (NTT DoCoMo/ARIB 0.0)[:SOURce]:WCDMa:CHANnel[:I]|:QThe commands for determining the channel configuration are under this node. For the sense oftransmission DOWN (:WCDM:LINK DOWN) the settings cannot be separately set to I and Qcomponent; :I and :Q need not be specified.Example: :WCDM:CHAN2:TYPE PERCFor UP, however, there is the multiplex setting (UPMulti) with which settings are distinguishedbetween I and Q. :I is optional, :I is used if no indication is made.Example: :WCDM:CHAN2:I:TYPE PERChas the same meaning as :WCDM:CHAN2:TYPE PERCExample for Q-component setting: :WCDM:CHAN2:Q:TYPE PERCThere are some commands which do not make a distinction between I and Q::WCDM:CHAN:LCOD:WCDM:CHAN:LCOD OFFS:WCDM:CHAN:SCOD:LMS[:SOURce]:WCDMa:CHANnel[:I]|:Q:TYPE PERCh | CCPCh | DPCH | DPDCh | DPCCh |ALLDThe command selects the channel type.PERCh Perch Channel (only for :WCDM:LINK DOWN)CCPCh Common Control Physical Channel (not for :WCDM:LINK UPM)DPCH Dedicated Physical Channel (not for :WCDM:LINK UPM)ALLD All Data (not for :WCDM:LINK UPM)DPDCh Dedicated Physical Data Channel (only for :WCDM:LINK UPM)DPCCh Dedicated Physical Control Channel (only for :WCDM:LINK UPM)Example: :SOUR:WCDM:CHAN2:I:TYPE PERC *RST value is DPCH*RST value is PERC for channel 0, mode 8, downlink[:SOURce]:WCDMa:CHANnel[:I]|:Q:SRATe D16 | D32 | D64 | D128 | D256 | D512 | D1024The command determines the symbol rate. The values depend on the channel type.Example: :SOUR:WCDM:CHAN2:I:SRAT D64 *RST value is D32*RST value is 16 for channel 0, mode 8, downlink[:SOURce]:WCDMa:CHANnel[:I]|:Q:SCODe 0 to 511The command is used to set the short code of the spread code. The upper limit depends on:WCDM:CRAT, :WCDM:SRAT and :WCDM:CHAN:TYPE.Example: :SOUR:WCDM:CHAN2:I:SCOD 123 *RST value is (+9)*RST value is 0 for channel 0, mode 8, downlink:SOURce]:WCDMa:CHANnel:LCODe #H0 to #H3FFFF (#H1FFFFFFFFFF)The command determines the long code of the spread code.Example: :SOUR:WCDM:CHAN2:LCOD #H3FFF *RST value is #H1[:SOURce]:WCDMa:CHANnel:LCODe:OFFSet 0 to 40959 (81919)The command is used to set the long code offset of the spread code.Example: :SOUR:WCDM:CHAN2:LCOD:OFFS 345 *RST value is 01125.5555.03 3.157 E-9
