| 摘 要： | 为在混响室中对线缆差模干扰时的设备进行辐射敏感度测试,基于BLT方程,以常见的平行双导线为研究对象,分析了差模干扰时影响线缆方向性系数的因素,计算了线缆最大方向性系数的取值范围。然后根据前期研究中提出的测试方法,在混响室中和开阔场中进行试验,对计算结果进行了验证。试验结果表明,按照所得的最大方向性系数的计算值,可以确保混响室中辐射敏感度测试结果与开阔场相一致。

| Abstract: | To perform radiated immunity testing for equipment with transmission lines as the coupling channel of differential-mode interference, the factors influencing the value of the maximum directivity of the two parallel lines is analyzed and the range of the maximum directivity is calculated based on the theory of the BLT equation. The calculated results are then validated by two experiments performed in a reverberation chamber and an open area, respectively, with the test method proposed in our former investigation. The experiments show that, the unification of the testing results in a reverberation chamber and an open area can be ensured using the calculated value of the maximum directivity of the lines. |
