混响室条件下电子设备辐射敏感度测试方法

按照连续搅拌和步进搅拌2种运行模式,构建了混响室条件下电子装备辐射敏感度的测试系统,对典型卫生医疗设备进行了抗扰度测试,研究了混响室的不同工作模式对实验结果的影响.结果表明:搅拌器工作于步进模式时受试设备的敏感度要高于连续搅拌情况,连续搅拌模式下,搅拌器的搅拌速度越快,受试设备的敏感度越低.

Methods of Radiated Immunity Testing of Electronic Device Using Reverberation Chamber

This paper established a radiated immunity testing system of electronic device in Reverberation Chamber.The influence of different work modes to the experimental results was investigated.Representative medical equipment was experimented when the RC addresses mode stirred and mode tuned.Repeatability and reproducibility of these testing methods were investigated by repeating the test with different stirred rates.The experimental results demonstrated that the interference thresholds of mode stirred were lower than mode tuned;and care should be taken during continuous mode stirring that the tuner rotation speed was important.With the speed of tuner rotation increase,the interference thresholds decrease.
