Using WCDMA/HSPA+ Signal Analyzer
Introduction
This WCDMA/HSPA+ Signal Analyzer can be used to test a WCDMA transmitter including
HSDPA/HSPA+ signals to check the base station
’s compliance with following standards documentation.
 3GPP TS 25.104 Base Station radio transmission and reception
 3GPP TS 25.141 Base Station (BS) conformance test
 3GPP TS 25.211 Physical channel and mapping of transport channels onto physical channels
 3GPP TS 25.212 Multiplexing and channel coding
 3GPP TS 25.213 Spreading and modulation
The instrument automatically makes standard defined measurements using the measurement
methods and limits as defined in the standards. Detailed measurement results allow you to analyze
WCDMA and HSPA+ system performance. You may alter the measurement parameters for specialized
analysis. Pass/Fail testing with standard defined or user defined upper and lower limits and the
Pass/Fail indictor help you to determine base station performance easily.
This instrument provides the following measurement tools for WCDMA/HSPA+ system:
 Spectrum Analysis
