Study on testing Spurs Emission of TD-LTE Base Station

It¡¯s necessary to deeply understand how to test Spurs Emission to develop commercial TD-LTE Base Station or optimize the wireless network. Studying test method includes three parts. Firstly, thoroughly analyzing test platform is needed. Secondly, discussing the related difference from distinguishingly configuring spectrum analyzers will help to understand which one is most significant. Last, we analyze the measurement accuracy. It¡¯s shown that test system accuracy is composed by two parts, including external and internal configuration. External configuration means reasonable test platform, including spectrum analyzer and band stop filter. Internal configuration means how to configure spectrum to get an optimized test result, which can indicate the actual level of low power signal.
