SMIQDigital Standard 3GPP W-CDMA (FDD)Channel table:Fig. 2-118DIGITAL STD – WCDMA/3GPP – BS CONFIGURATION / channel table menuBelow the general parameters of the current base station follows a table comprising all the parametersthat can be edited on a channel-specific basis.CH NOChannel number, consecutive from 0 to 138. This value cannot be edited. Allrows are displayed even if the channels are inactive. Activating/deactivating isvia STATE at the end of the row.TYPESYMBOL RATECHANNELIZATIONCODEChannel type which is permanently linked to the channel number and whichcannot be edited:The first 11 code channels in the table are occupied for the special channelsP-CPICH to DL-DPCCH. All other code channels are DPCHs. The channeltype is a pure display parameter and cannot be edited. Not all parameters inthe table can be edited. This depends on the type of channel.Symbol rate of channel in ksps.The value range of symbol rate is modified depending on the channel type.For example, the P-CPICH is fixed at a symbol rate of 15 ksps by the 3GPPstandard, but all symbol rates between 7.5 ksps and 960 ksps are available fora DPCH.IEC/IEEE-bus command :SOUR:W3GP:BST3:CHAN12:SRAT D30KThe channelization code (previously called spreading code number) isselected here. The code channel is then spread with the channelization code(spreading code) thus determined. The value range of the channelization codedepends on the symbol rate of the channel. A fixed channelization code isallocated to a few channels as standard (the P-CPICH e.g. always uses thechannelization code 0).The maximum value range extends from 0 to chip _ rate( = 3.84Mcps)−1symbol _ rateIEC/IEEE-bus command :SOUR:W3GP:BST3:CHAN12:CCOD 111125.5555.03 2.197E-9
