SMIQ Enhanced Functions For Digital Standard 3GPP W-CDMA (FDD)
1125.5555.03 E-92.241
2.15.3.1.1 P-CCPCH/BCH with System Frame Number
In addition to channel-coded reference measurement channels, test specifications for mobile or UE
tests (see [1]) often stipulate a channel-coded P-CCPCH (BCH). With the Enhanced P-CCHCP/BCH
State 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 Standard
Enhanced mode (Enhanced P-CCHCP/BCH State Off).
ENHANCED P-
CCPCH/BCH (INCL.
SFN) STATE
This switch enables one P-CCPCH/BCH and one DPCH to be generated as
enhanced channels (OFF) instead of the 4 DPCHs.
IEC/IEEE-bus command :SOUR:W3GP:BST:ENH:PCCP:STAT ON
With 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 a
DPCH.
• If the P-CCPCH is activated under Specific Enhanced Channel Settings, it will automatically be
generated 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 frames
