The transversal electromagnetic mode which can be developped in the SL 150 strip line, provides the opportunity for doing EMC testing inside the strip line. The strip line is specified in EU directives 2004/104/EG, 2005/83/EG and 2009/0154 (COD). Frequency range and general settings are also described in ISO 11452‑1. The SL 150 allows testing electrical/electronic sub modules (EUB). The SL 150 consists of two parallel metal plates. The EUT is arranged in the middle between these plates. The largest outer dimension of the EUT should not be more than 1/3 of the plate distance. The ground is on the lower plate and the isolated upper plate is supplied with RF energy. Between the plates, an electromagnetic field will be established. A typical test configuration consists of signal generator, power amplifiers, power meters and SL 150. To avoid interactions with the environment, the test should be run in an anechoic test chamber.
在 SL 150 平行板（Strip Line）中可產生的橫向電磁模式（Transversal Electromagnetic Mode, TEM），使其成為進行 EMC 測試的理想設備。該平行板符合歐盟指令 2004/104/EG、2005/83/EG 以及 2009/0154 (COD) 的規範。其頻率範圍及一般設定亦詳載於 ISO 11452‑1 標準中。
SL 150 適用於測試車用電氣/電子子模組（EUB），其結構由上下兩個平行金屬板組成，被測設備（EUT）置於兩板中間。EUT 最大的外部尺寸不得超過板間距離的三分之一。下板接地，上板絕緣並供應射頻能量。兩板間會建立出均勻的電磁場。
典型的測試組態包括：信號產生器、功率放大器、功率計與 SL 150 平行板。為避免與外部環境的相互干擾，測試建議在無反射電波暗室中進行。
