SMIQEnhanced Functions For Digital Standard 3GPP W-CDMA (FDD)----------------------Common Enhanced Channel Settings-----------------------------------------------------OVERALL SYMBOLRATEDPDCH POWERSets the overall symbol rate in ksps and the required uplink DPDCHs.For an overall uplink symbol rate of up to 960 ksps only one DPDCH isrequired in addition to the normally available DPCCH. Further DPDCHs with960 ksps each are added to the signal to obtain a higher overall symbol rate(maximum 6 DPDCHs).The enhanced channel table is adapted depending on the setting forOVERALL SYMBOL RATE (e.g. number of active enhanced channels). In thechannel table of the higher MS1 menu, the enhanced channels are marked byan additional E (in addition to CHANNEL NUMBER).If the CHANNEL CODING STATE switch is set to ON, there is a close relationbetween the settings CODING TYPE and OVERALL SYMBOL RATE:MEASURE__12.2: OVERALL SYMBOL RATE = 60 kspsMEASURE__64:OVERALL SYMBOL RATE = 240 kspsMEASURE_144:OVERALL SYMBOL RATE = 480 kspsMEASURE_384:OVERALL SYMBOL RATE = 1 * 960 kspsAMR_CODER:SYMBOL RATE DPDCH = 60 ksps;When a parameter is changed (CODING TYPE or OVERALL SYMBOL RATE)the associated parameter is adapted automatically.IEC/IEEE-bus command :SOUR:W3GP:MST:ENH:ORAT X2Sets the channel power (-60 dB to 0 dB) of the DPDCHs. Each active DPDCHis sent with this power. If the EXTERNAL POWER CONTROL STATE switchis set to ON, this power is also the start power for the power control.Note:Starting the ADJUST TOTAL POWER menu parameter at the topmenu level of 3GPP W-CDMA adapts all the channel powers(POWER DB parameter) of the mobile stations (and, thus, also thePOWER START values of the set enhanced channels) so that theaverage overall power of all the activated channels is 0 dB withreference to the LEVEL in the SMIQ display.IEC/IEEE-bus command :SOUR:W3GP:MST:ENH: POW:DPDC -30.0ENHANCED DPCCHSTATEThis parameter is used to determine whether the DPCCH is calculated asenhanced channel (on the data generator) or as "normal" channel (on themodulation coder).STATE = ON:The DPCCH is calculated as enhanced channel. This setting is useful whenExternal Power Control is active.STATE = OFF:The DPCCH is calculated as a normal channel. This setting is useful for allmeasurements which require no External Power Control.IEC/IEEE-bus:SOUR:W3GP:MST:ENH:DPCC:STAT OFF1125.5555.03 2.255E-9
