SMIQDigital Standard IS-95 CDMAMODE...Selection between the different modes for generating a forward link signal orreverse link signals. The REV_LINK modes will be described in the followingsections.FWD_LINK_18 Activates the generation of a forward link signal withup to 18 code channels (channel No. 0 to 17).The Walsh code (WALSH CODE) and the source formodulation data (DATA) can be determinedindividually for each channel.Each channel can be switched on/off (STATE).The relative power (POWER) of channels 0 (pilot), 1and 2 can be freely determined in range -30 dB to0 dB.The power setting of channel 3 also determines thepower setting of channels 4 to 17. This means thatchannels 3 to 17 all have the same power providedwhen the channels are switched on.IEC/IEEE-bus :SOUR:IS95:MODE FLIN18FWD_LINK_64REV_LINKREV_LINK_CODEDActivates the generation of a forward link signal withup to 64 code channels.Walsh codes 0 to 63 (WALSH CODE) are assignedto the channels.The source for modulation data (DATA) can bedetermined individually for each channel.Each channel can be switched on/off (STATE).The relative power (POWER) of the pilot channel(Walsh 0) can be freely determined in range -30 dB to0 dB.The power setting of channel 1 also determines thepower setting of channels 2 to 63. This means thatchannels 1 to 63 all have the same power providedwhen the channels are switched on.IEC/IEEE-bus :SOUR:IS95:MODE FLIN64Activates the generation of a reverse link signalwithout channel coding. A selection between the fullrateand half-rate mode (RATE) is possible.IEC/IEEE-bus :SOUR:IS95:MODE RLINActivates the generation of a reverse link signal withchannel coding. A selection between the accesschannel and traffic channel with different rates ispossible.IEC/IEEE-bus :SOUR:IS95:MODE RLCO1125.5555.03 2.137E-9
