摘要
结合最近颁布的IEC 61000-4-20(2007版)标准,研究了GTEM室的传输特性指标。通过对GTEM室场强参数的预测试,得出了场强与功放增益的频域特性。结果表明场强与功放增益的波动以及GTEM室传输特性的改变具有很大的关系。在此基础上进一步阐述了GTEM室辐射敏感度自动测试系统中室内场强自动控制过程。
The transmission characteristic index of GTEM cell was studied according the latest standard of IEC61000-4-20 （2007 version）. The frequency characteristic of the field intensity and the gain of power amplifier were obtained through the anticipated test of the field parameters of the GTEM cell. It was showed that the field intensity in the GTEM cell has great relationship with the gain fluctuation of the amplifier and the transmission characteristic change of the GTEM cell. The automatic control process of the field intensity in the automatic radiated susceptibility test system of the GTEM cell was explained.
