示波器在电磁兼容性试验中耦合方式的选择与应用研究

Research on Selection and Application of Coupling Mode of Oscilloscope in Electromagnetic Compatibility Test

针对电磁兼容性试验中示波器耦合方式的选择问题,文章对示波器耦合方式进行原理分析,结合《军用设备和分系统电磁发射和敏感度要求与测量》(GJB151B-2013)中典型的电磁兼容性试验进行解释说明,最后通过试验验证了该选择方法的合理有效性。

In order to select the coupling mode of the oscilloscope in the electromagnetic compatibility test, the principle of the oscilloscope coupling mode is analyzed firstly. Then combined with the typical electromagnetic compatibility tests in "Electromagnetic emission and sensitivity requirements and measurements for military equipment and subsystems"(GJB 151 B-2013), the explanation is given. Finally, the rationality and effectiveness of the selection method is verified by experiments.
