Leaders in innovation are joining forces

Comtest Engineering and Rohde & Schwarz are collaborating to offer optimised reverb test system solutions for all relevant compliance standards such as IEC 61000-4-21, ISO 11451-5, ISO 11452-11, MIL-STD-461G, RTCA/DO-160G, EUROCAE/ED-14 and various automotive OEM standards.

Why? Real-world electromagnetic environments are changing, driven by highly integrated electronic products with multiple, widespread interference sources. Conventional two-dimensional illumination techniques cannot fully address such complex test scenarios. Therefore, demand for EMC tests in Reverberation Chambers (RVC) is growing.

Rohde & Schwarz’s Product Manager Jens Medler says, “RVC is also in discussion for CISPR 32 emission measurements above 1 GHz. Our fully compliant EMI test receivers, broadband amplifiers, R&S ELEKTRA automation software and other system components enable immunity and emission testing in RVC chambers.”

Bas de Groot, Owner of Comtest Engineering, explains, “A reverb room is equipped with an integrated mode stirrer system that turns stepwise during testing. The benefits of mode-stirred RVC chambers are high repeatability, testing heavy and large EUTs, and better representation of real-life environments.”

Comtest offers worry-free EMC test chamber solutions. Rohde & Schwarz offers industry-leading EMC test solutions for everything from debugging to full compliance.

The advantages of screwing clampings

It is not easy to replace soldered finger-stocks in the doorframe of your test chamber. That’s why we switched already in 1999 to screw clampings. Our colleague Gerco van Diemen explains why you will benefit from this. “Clampings hold the finger-stocks in place. Finger-stocks are the copper clamps that ensure that the door of a test chamber is completely sealed and no RF leakage occurs. They are a vulnerable part of a chamber’s Faraday cage construction. Traditionally, these are soldered, but we have developed a way where using screws has the same protective effect.”

CISPR25 Edition 5 & partial absorber lining

What are the design criteria for CISPR25 towards absorber lining as per the latest standard version? CISPR 25 was initially published in 1995. The 5th edition, published in 2021, significantly expanded the category of receivers by including new technologies such as Wi-Fi, V2X, navigation, and more.

Our services include maintenance and validated testing. We recommend that both are executed by authorized personnel only. Our expert teams can perform preventive maintenance on RF-shielded doors, mode-stirrer systems, and positioning equipment such as turntables. We also offer validation services to see if your EMC test chamber or RF-shielded room still functions within its intended limits and avoiding unexpected down-time or product recalls at the same time.

A shielded room can perform conducted emission and immunity EMC measurements, eliminating harmful external influences, leading to more accurate and consistent test results. Being a Faraday cage, a shielded room will not only improve test results but will also form an excellent aid in protecting information and essential hardware. Comtest can assist governments, the military, financial institutions, and large corporations in protecting what matters most in critical situations. We offer the highest quality, sensitivity, and security before, during and after working with you.
