Enhanced Functions For Digital Standard 3GPP W-CDMA (FDD)SMIQ----------------------External Power Control-----------------------------------------------------------------------------EXTERNAL POWERCONTROL STATESwitch for activating or deactivating the external power control mechanism ofall enhanced channels.In the OFF state, the following menu parameters are not effective:POWER UP RANGE,POWER DOWN RANGE,POWER STEP,IEC/IEEE-bus command:SOUR:W3GP:MST:ENH:EPOW:STATONPOWER STEPPOWER UP RANGEPOWER DOWNRANGEStep width (0.25 to 6.0 dB) by which – with the external power controlmechanism switched on – the channel powers of the activated enhancedchannels in the timeslot grid are increased or decreased within the setdynamic range.IEC/IEEE-bus command:SOUR:W3GP:MST:ENH:EPOW:STEP1.0Dynamic range (0 to 30 dB) in which – with the external power controlmechanism switched on – the channel powers of all the activated enhancedchannels can be increased. The value POWER UP RANGE can be changed byPOWER STEP. If the dynamic range is exceeded, the warning "MAX. POWERUP REACHED” is displayed.The resulting external power control dynamic range (= POWER UP RANGE –POWER DOWN RANGE) must not exceed 30 dB. For this reason, thePOWER UP RANGE is limited as a function of the POWER DOWN RANGE.IEC/IEEE-bus command:SOUR:W3GP:MST:ENH:EPOW:RANG:UP 10.0Dynamic range (0 to 30 dB) in which – with the external power controlmechanism switched on – the channel powers of all the activated enhancedchannels can be decreased. The value POWER DOWN RANGE can bechanged by POWER STEP. If the dynamic range is underranged, the warning"MIN. POWER DOWN REACHED" is displayed.The resulting external power control dynamic range (= POWER UP RANGE –POWER DOWN RANGE) must not exceed 30 dB. For this reason, thePOWER DOWN RANGE is limited as a function of the POWER UP RANGE.IEC/IEEE-bus command:SOUR:W3GP:MST:ENH:EPOW:RANG:DOWN 10.01125.5555.03 2.254 E-9
