Digital Standard IS-95 CDMASMIQ2.12.5 Menu IS-95 CDMA Standard - Reverse Link Signal withoutChannel CodingMenu DIGITAL STD - IS-95 provides access to settings for IS-95 CDMA signal generation. Thefollowing figure shows the menu for generating the reverse link signal (transmit signal of mobile station)without signal coding. The previous section showed the menu for generating the forward link signals aswell as the parameters that are identical for both modes.Menu selection: DIGITAL STD - IS-95- MODE - REV_LINKFREQIS95100. 000 000 0 MHzLEVEL-30.0 dBmPEP - 23.3 dBmFREQUENCYLEVELANALOG MODVECTOR MODDIGITAL MODDIGITAL STDLF OUTPUTSWEEPLISTMEM SEQUTILITIESPHSIS95NADCPDCGSMSTATEMODE...SET DEFAULTMODULATION...TRIGGER MODE...EXECUTE TRIGGERTRIGGER...CLOCK...OFF ONREV_LINKQPSK IS-95AUTOINTINTRATE FULL_RATE HALF_RATEBURST RANDOMIZER OFF ONDATA 0000-----------------CHANGE DATA------------------SELECT DATA LIST...CURRENT: R&STDMCOPY CURRENT DATA LIST TO...DELETE DATA LIST...EDIT DATA LIST...Fig. 2-86Menu DIGITAL STD - IS-95 - MODE - REV_LINKSTATE to CLOCKRATEBURSTRANDOMIZERsee section "Menu IS-95 CDMA-Standard- Forward Link Signal"Selection of full-rate or half-rate transmission of modulation data. Thisselection is only possible in the reverse link mode.In the half-rate mode, only 8 of 16 power control groups of a frame aretransmitted ("power gating").IEC/IEEE-bus command :SOUR:IS95:RATE HALFSwitch on/off of burst randomizer. This selection is only possible during halfratetransmission in the reverse link mode.OFF Every second power control group is transmitted.ON A random algorithm determines which eight of the 16 powercontrol groups of a frame will be transmitted.IEC/IEEE-bus command :SOUR:IS95:RAND ON1125.5555.03 2.146E-9
