WCA-230A无线通信测试仪在TD-SCDMA调测中的典型应用

Application of WCA-230A Wireless Communication Analyzer in TD-SCDMA Test

本文介绍了利用WCA-230A无线通信测试仪测试TD-SCDMA中的一些关键信号的方法,特别是利用实时信号分析的功能来捕捉TD-SCDMA在接入、切换时的突发(Burst)信号,并利用WCA-230A提供的灵活的调制分析能力,方便地把仪器设置为TD-SCDMA模式,以解调TD-SCDMA信号,并分析星座图及EVM(调制误差矢量)。

The paper introduces methods of testing the key signals of TD-SCDMA using WCA-230A wireless communication analyzer. It especially presents capturing the burst signal of TD-SCDMA when the access or handover proceed using the real time signal analysis function, and it uses flexible modulation domain analysis ability to demodulate the TD-SCDMA signal and analysis signals in constellation and EVM (error vector of modulation).
