Decoupling Clamps for Reliable EMC Testing in Accordance with IEC 61000-4-6:2023

With over 50 years of expertise in testing, certification, and measurement technology, SIQ Ljubljana continues to support the industry with high-quality solutions designed to meet modern compliance standards. Our latest development, the decoupling clamps, has been engineered in accordance with the latest edition of the IEC 61000-4-6:2023 (Edition 5.0) standard for conducted immunity testing.

The fifth edition of the IEC 61000-4-6 standard introduces the requirements for decoupling clamp. It specifies that the decoupling shall be greater than 5 dB starting from 1 MHz and more than 14 dB in a 50-ohm system. The SIQ decoupling clamps consistently exceed these limits, providing confidence in test validity and ensuring compliance with current basic standards.

Operating in the frequency range from 150 kHz to 80 MHz, the decoupling clamp is suitable for a wide range of conducted immunity testing applications. Whether you are testing information technology equipment, industrial devices, or consumer electronics, the decoupling clamps integrate seamlessly into your setup, ensuring reliable and reproducible test conditions.

As part of our commitment to quality and technical excellence, SIQ has developed the decoupling clamps entirely in-house, based on practical laboratory experience and the demands of modern EMC testing.

The CMAD clamps are already in use in SIQ’s own ISO/IEC 17025-accredited EMC laboratory, where they contribute to reliable, repeatable, and compliant immunity tests.
