Digital Standard 3GPP W-CDMA (FDD)SMIQTRANSMITDIVERSITYNUMBER OF PAGEINDICATORS PERFRAMEMULTI CHANNELEDIT...The 3GPP standard describes various forms of transmit diversity. The signal isdistributed with different coding between two antennas. The SMIQ cansimulate the signal for one of the two antennas. A fixed diversity scheme isassigned to each channel type:DPCH, PCCPCH, SCCPH: STTD (Space time block coding transmitantenna diversity).Primary SCH, secondary SCH: TSTD (Time switched transmit diversity for SCH).Both schemes are described in detail in reference [1], section 5.3.1.If transmit diversity is required, the antenna whose signal is to be simulatedcan be specified.OFF:no transmit diversityANTENNA 1: calculate antenna signal for antenna 1 and display resultANTENNA 2: calculate antenna signal for antenna 2 and display resultIEC/IEEE-bus command :SOUR:W3GP:BST1:TRAN:DIV ANT1The number of page indicators per frame in the page indication channel (PICH)can be defined thanks to this menu item. The value range is 18, 36, 72, 144.IEC/IEEE-bus command :SOUR:W3GP:BST2:PIND:COUNT D36A certain number of DPCHs can be configured with just a few keystrokesusing this menu item, see section 2.14.2.7.CHANNEL GRAPH This menu item gives an overview of the assigned channels, see section 2.14.2.8.CODE DOMAIN This menu item indicates the assignment of code domain, see section 2.14.2.9.1125.5555.03 2.196E-9
