摘要
针对混响室确认系数传统测量方法存在的耗时长、测量不确定度大等问题,根据GB/T 17626.21-2014测试要求,提出电磁混响室的辐射发射快速校准法。确定了电磁辐射发射快速校准流程,开发了混响室辐射发射快速校准软件。5G通信基站的辐射发射快速校准测量结果表明,快速校准法能够有效地测量出混响室确认系数,且测量时间短,测量结果的不确定度小。
Aiming at the problems of long time consumption and large measurement uncertainty in the traditional measurement method of the chamber validation factor,according to the test requirements of GB/T 17626.21-2014,a fast method for radiation emission of the electromagnetic reverberation chamber was proposed.A fast calibration process for electromagnetic radiation emission was determined,and a fast calibration software for radiation emission in reverberation chamber was developed.The fast calibration measurement results of 5G communication base station show that the fast calibration method can effectively measure the chamber validation factor,and the measurement time is short,and the uncertainty of the measurement result is small.
