According to ETSI TS 125 141 V7.11.0 (2008-04) Technical Specification
- 6.5.1 Occupied Bandwidth
In-band portion of emitted signal is displayed in % in Output Equations window. Bandwidth is set to 5 MHz, as described in Minimum Requirements section. In order to display the results:
1. Run the simulation by clicking on Run/Stop System Simulator button.
2. Stop simulation or wait until simulation is complete. Click Analyze button.
Bandwidth may be changed by right-clicking on OccBWPwrDB output equation, selecting Properties, then entering desired value in Channel BW field.
WCDMA/HSDPA TX Conformance Testing:
According to 3GPP TS 25.141 V6.10.0
Test Models for TX conformance testing are selected through TestModel parameter in Global Definitions. Multiple channel configurations available for some of the tests are selected by the ChannelConfig parameter. In case of invalid entries, these parameters are rounded to the nearest valid value.
The rated output power, PRAT, of the base station is set by OutPowerLevel_dBm. The nominal values are specified as follows:
The center frequency is specified by CarrierFreq_MHz. Its value should be set according to the values specified in Section 3.4 of the specification document.
Test Model configurations are specified in the tables below:
