Results are displayed in ACLR table for BS channel offset 5 MHz and 10 MHz.


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:
