| 摘 要： | 杂散辐射是衡量基站性能的重要指标之一。文中用安捷伦科技公司最新发布的低档频谱分析仪CXA N9000A来测试TD-LTE基站发射机共站杂散辐射,采取外接低噪声放大器和带阻滤波器的方法,解决了测试过程中频谱仪灵敏度及动态范围不够的问题,降低了测试对仪器的要求和测试成本,实现了对-100 dBm左右的共站杂散信号的准确测试。

| Abstract: | Spurious Emission is one of the most important performance indexes of a base station.A measure method and it simplementation of TD-LTE transmitter spurious emission with an Agilent's low end spectrum analyzer,CXA N9000A,is introduced.This test system includes a LNA and a band stop filter to increase level of sensitivity and dynamic range and fulfills the accurate measure of co-location spurious emission signal with the amplitude of-100 dBm around. |
