摘要

横向电磁(TEM)波导用于电磁兼容测量的抗扰度和发射测试。本文介绍了一种新研制的瞬变电磁法波导——S-LINE。到目前为止，已知的测试单元可以被视为加宽的非对称同轴线，其中EUT受到内外导体之间电磁场的影响。相比之下，S-LINE基本上由对称的两线TEM线组成，这些线被安排在一个电屏蔽的外壳中。通过以对称线产生电场，该电池提供了比传统电池更大的测试体积。S-LINE可在150 kHz至1 GHz的频率范围内使用，可用于产品开发期间的预认证发射和抗扰度测试。

S-LINE: a newly developed TEM waveguide for EMC measurements

Transverse electromagnetic (TEM) waveguides are used in EMC measurements for immunity and emission tests. The paper describes a newly developed TEM waveguide, the S-LINE. Test cells known so far can be regarded as widened unsymmetrical coaxial lines with the EUT subjected to the electromagnetic field between the inner and outer conductor. By contrast the S-LINE essentially consists of symmetrical two-wire TEM lines that are arranged in an electrically shielded enclosure. By generating the field with a symmetrical line the cell offers a larger test volume than that of conventional cells. The S-LINE can be employed in the frequency range 150 kHz to 1 GHz and can used for precertification emission and immunity testing during the development of a product.
