R&S®SMIQ-B45 Digital Standard W-CDMA according to 3 GPP (FDD)
Key Facts
- The software supports the standard with 3.840 Mcps and 15 slots/frame in line with the 3G harmonization recommendation. The maximum number of data channels is 512.
- The test models 1 to 4, as predetermined in the standard, can be generated by a simple selection.
- Up to four base stations or mobile stations can be simulated, each having 128 code channels, separately selectable T sector and long code initial values, and different power of the SCH, etc.
- Symbol rate, spreading code, power, data content (various PRBS or bit patterns) and data offset can be selected for each code channel (data offset is a time offset that can be used to influence the crest factor).
- Perch channels, SCCPCH and DPCHs can be generated in the downlink; PRACH, PCPCH, DPCCH and DPDCHs in the uplink; each channel with its specific slot structure.
- The TPC bits may be used for varying the transmit power of a channel versus time.
- The downlink signals can be calculated for antenna 1 or 2 (transmit diversity).
- The long signal length of up to 13 frames (with 3.84 Mcps) allows realistic signals to be generated.
