Digital Standard IS-95 CDMASMIQSET DEFAULTProvides the default setting for the channel configuration of the forward linkmodes.For FWD_LINK_18:- channels 0 to 8 are switched on- the power of the pilot channel (channel 0) makes out 20% of the total power(-7 dB).- channel 1 is set as sync channel by WALSH CODE 32- channel 2 is set as paging channel- the remaining 7 channels are configured as traffic channelsThe power setting was selected according to the "Base Station Test Model"of TIA standard IS-97.For FWD_LINK_64:- all 64 channels are switched on- the power of the pilot channel makes out 20% of the total power (-7 dB).- the remaining 80% of the transmit power is distributed equally on theremaining 63 channels.IEC/IEEE-bus command :SOUR:IS95:PRESMODULATION...Opens a window for setting the modulation parameters.Fig. 2-82Menu DIGITAL STD - IS-95 - MODULATION..., equipped with options modulation coderSMIQB20, data generator SMIQB11 and SMIQB42(MODULATION...) MODULATION TYPE Indicates the modulation type.CHIP RATESetting value of chip clock frequency.Preset to 1.2288 Mcps.IEEE-bus command :SOUR:IS95:CRAT 1.2 MHZ(MODULATION...) FWD LINK FILTER... Opens a window for selecting the baseband filtersfor the forward link. A selection between the FIRfilters defined in IS-95, the Nyquist filters COS andSQRCOS or a user-defined filter USER (cf. SectionDigital Modulation) is possible. A FIR filter is presetwith equalizer according to IS-95.IEEE command :SOUR:IS95:FILT:FTYP EIS951125.5555.03 2.138E-9
