摘要
主要介绍了低频磁场抗扰度发射天线(赫姆霍兹线圈)的天线因子的测量方法与步骤。对各种线圈间距情况下的赫姆霍兹线圈天线因子进行测量,使得电磁兼容实验室能够利用这些天线因子的数据更加便捷地进行整车低频磁场抗扰度的测试。
This article mainly introduces the measurement methods and procedures of low-frequency magnetic field immunity antenna （Helmholtz coil） factor. The electromagnetic compatibility laboratory can make the low-frequency magnetic field immunity test faster and more convenient by using these antenna factors which comes from the measurements of Hehnholtz coil antenna factor at various coil space.
