Using TD-SCDMA Signal Analyzer
Introduction
The Time Division-Synchronous Code Division Multiple Access, also known as TD-SCDMA, is a 3G
mobile telecommunications standard that is pursued by the Chinese Academy of Telecommunications
Technology (CATT) in the People's Republic of China. The TD-SCDMA uses the TDD scheme while
the WCDMA uses the FDD.
This TD-SCDMA Signal Analyzer can be used for testing of TD-SCDMA systems, made according to
the following standard documentation.
 3GPP TS 25.105 Base Station radio transmission and reception (TDD)

3GPP TS 25.142 Base Station conformance testing (TDD)
 3GPP TS 25.222 Multiplexing and channel coding (TDD)
 3GPP TS 25.223 Spreading and modulation (TDD)
The instrument automatically makes standard defined measurements using the measurement
methods and limits as defined in the standard. The detailed results allow you to analyze TD-
SCDMA/HSDPA 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.
