摘要
通过介绍汽车屏蔽线缆的物理结构,阐述屏蔽线缆屏蔽效能测试标准和方法的研究,运用线注入法测试方法来测量表面转移阻抗,从而求得屏蔽线缆的屏蔽效能。通过对不同车型屏蔽线缆测试结果的分析,来评估在频率范围100 kHz^1 GHz内可以辨别汽车屏蔽线缆的屏蔽效能。
Through the introduction of the physical structure of automobile shielded cable,shielding cable shielding effectiveness testing standard and method of study,using the line injection test method to measure the surface transfer impedance,therefore indirectly get the shield cable shielding effectiveness.Through the analysis of the test results of the shielded cable of different vehicle types,the shielding effectiveness of the automobile shielded cable can be identified in the frequency range of 100 kHz-1 GHz.
