SMIQEnhanced Functions For Digital Standard 3GPP W-CDMA (FDD)POWER UP RANGEPOWER DOWNRANGEPOWER CONTROLGRAPH ►Dynamic range (0 to 30 dB) by which – with external power control mechanismswitched on – the channel powers of all activated enhanced channels can beincreased. The value POWER UP RANGE can be changed by POWER STEP.If the dynamic range is exceeded, the warning MAX. POWER UP REACHED isdisplayed.The resulting external power control dynamic range (= POWER UP RANGE –POWER DOWN RANGE) may be 30 dB at max. which is why the POWER UPRANGE is limited as a function of the POWER DOWN RANGE.IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:EPOW:RANG:UP 10.0Dynamic range (0 to 30 dB) by which – with external power control mechanismswitched on – the channel powers of all activated enhanced channels can bedecreased. The value POWER UP RANGE can be changed by POWER STEP.If the dynamic range is underranged, the warning MAX. POWER UP REACHEDis displayed.The resulting external power control dynamic range (= POWER UP RANGE –POWER DOWN RANGE) may be 30 dB at max. which is why the POWERDOWN RANGE is limited as a function of the POWER UP RANGE.IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:EPOW:RANG:DOWN 10.0With this menu parameter selected, the display window is opened again and -with external power control mechanism switched on - the "current" deviation ofthe channel power from the set power start value of the correspondingenhanced channels is displayed graphically(see section 2.15.3.3).The display window is only shown if the EXTERNAL POWER CONTROLswitch is set to ON and if the specific POWER CONTROL switch is positionedto UP or DOWN in the downlink for at least one enhanced channel.Note :This window is opened automatically after calculation of the signalstriggered by STATE = ON or MOD ON but can be closed againmanually by the user. This menu parameter allows the insertion ofthe window again without recalculating the signal.Note:With Enhanced P-CCPCH/BCH State On in the downlink, only the DPCH is powercontrolled.The P-CCPCH always has the power set in the enhanced channel table.1125.5555.03 2.247E-9
