SMIQEnhanced Functions For Digital Standard 3GPP W-CDMA (FDD)CHAN CODEPOWER STARTSets the corresponding enhanced channel.Downlink:The channelization codes of the downlink enhanced channels are variable from0 to -1 (3.840 MCPS/enhanced channel symbol rate). In the higher BS1 menu,the CH. CODE parameter is updated in the channel-table line determined by theENHANCED CHANNEL NUMBER.With Enhanced P-CCPCH/BCH State On in the downlink, the P-CCPCHautomatically has the data rate of 15 ksps and the channelization code 1stipulated in the standard.Uplink:The channelization codes of the uplink enhanced channels are constant anddescribed in [2].IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:CHAN11:CHNC 0Sets the channel (start) power of the corresponding downlink enhancedchannel. If the EXTERNAL POWER CONTROL STATE switch is set to ONand the channel-specific POWER CONTROL switch to UP or DOWN, thisvalue is the channel start power for the external power control mechanism.In the higher BS1 menu, the POWER DB parameter has to be updated in thechannel table line determined by the ENHANCED CHANNEL NUMBER.Note :By starting the ADJUST TOTAL POWER menu parameter in theupper menu level of 3GPP W-CDMA all channel powers (POWERDB parameter) of the BS1 channel table and thus also the POWERSTART values of the set enhanced channel are adapted so that theaverage overall power of all activated channels is 0 dB withreference to the LEVEL indicated in the SMIQ display.In the uplink, the channel start powers are determined via the parametersPOWER START DPCCH and POWER START DPDCH.IEC/IEEE-bus command :SOUR:W3GP:BST1:ENH:CHAN11:POW:STAR -30.0POWER CONTROLDATADATA DTCHDATA DCCHSwitch indicating the direction (UP or DOWN) with external power controlmechanism activated – with which the channel power of the correspondingdownlink enhanced channel is changed in the POWER STEP. The link is withreference to the high level of the external power control TTL signal at thebeginning of the pilot field of a timeslot.In the OFF state, the corresponding downlink enhanced channel of theexternal power control mechanism is not taken into account.IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:CHAN1:POW:CONT UPNote: The Power Control parameter is not provided with P-CCPCHsince it is not power-controlled.If channel coding is inactive, the data source for the data fields of the timeslotsof the corresponding enhanced channel can be selected here (DATA DTCHand DATA DCCH are nor displayed in this case.).If channel coding is active, data sources can be selected for the twocomponents of the channel (DTCH and DCCH).In a submenu the data sources PN9, PN11, PN15, PN16, ALL0, ALL1 and a24-bit PATTERN as well as any data lists DLISTxx can be selected. In the firstuplink enhanced channel (DPCCH) a data source cannot be indicated sinceno data field is available for this channel in the timeslots.IEC/IEEE-bus :SOUR:W3GP:BST:ENH:CHAN1:DATA PN9IEC/IEEE-bus :SOUR:W3GP:BST:ENH:CHAN1:DATA:PATT #H3F, 8IEC/IEEE-bus :SOUR:W3GP:BST:ENH:CHAN1:DATA:DSEL 'name'1125.5555.03 2.251E-9
