SMIQEnhanced Functions For Digital Standard 3GPP W-CDMA (FDD)2.15.3.1.1 P-CCPCH/BCH with System Frame NumberIn addition to channel-coded reference measurement channels, test specifications for mobile or UEtests (see [1]) often stipulate a channel-coded P-CCPCH (BCH). With the Enhanced P-CCHCP/BCHState activated, the SMIQ can generate this test scenario.The SMIQ then offers one P-CCPCH and one DPCH instead of the 4 enhanced DPCHs in the StandardEnhanced mode (Enhanced P-CCHCP/BCH State Off).ENHANCED P-CCPCH/BCH (INCL.SFN) STATEThis switch enables one P-CCPCH/BCH and one DPCH to be generated asenhanced channels (OFF) instead of the 4 DPCHs.IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:PCCP:STAT ONWith Enhanced P-CCHCP/BCH State On, this may affect the structure of the other operating menus:• The channel table under Specific Enhanced Channel Settings contains the P-CCPCH and aDPCH.• If the P-CCPCH is activated under Specific Enhanced Channel Settings, it will automatically begenerated with the sequence length 4096 frames (SFN period).• The maximum sequence length (SEQUENCE LENGTH DPCH) changes:- for symbol rates ≤ 30 ksps: 2044 frames- for symbol rates >30 ksps: 500 framesFig. 2-167Common Enhanced Channel Settings with Enhanced P-CCHCP/BCH State OnFig. 2-168Specific Enhanced Channel Settings with Enhanced P-CCHCP/BCH State On1125.5555.03 2.241E-9
