摘　　要：首先概述了89441A矢量信号分析仪以及其他一些测试仪器的在本测试中的主要功能;然后重点介绍了使用这些仪器对TETRA(陆上集群无线电系统)数字集群移动通信系统进行测试的方法,主要是对该系统中基站的发射机和接收机的一些重要性能指标来进行测试,如发射机的功率、载波频率容差和接收机的同道抗扰性、邻道抗扰性、参考灵敏度、寄生响应抗扰性;最后简单讲述了测试结果的评估。This paper generally introduces the principal functions of 89441A vector signal analyzer and other measuring equipments in this measurement at first. Then it stresses the way of the performance measurement of TETRA system equipments by these measuring equipments. The measurement contains the performance objectives of the transmitter and the receiver of the base station, such as power of transmitter, frequency tolerance of carrier, same channel anti-jamming, neighbor channel anti-jamming, reference sensitivity and parasite response anti-jamming. Finally, it simply introduces the evaluation of measuring result. 
