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.

Upgrading an EMC chamber with new absorbers on old tiles

Can you upgrade an EMC chamber and keep the old, glued ferrite tiles? “It’s possible”, says Uliana Trucchi, one of our technical consultants. “Say you want to replace your old absorbers because you need to meet performances over 1GHz, and you wish to keep the ferrite tiles because they are glued to the chamber’s walls and ceiling. That is exactly what the people from Nemko in Germany asked us for the chamber upgrade in the photo.”

The number of stirrer positions vs power

Testing time is valuable, so this post provides tips on optimising the number of stirrer positions in your reverberation chamber to fit your budget and test requirements. “There is a delicate balance between the number of stirrer positions and the amplifier power for a given reverberation chamber,” explains our R&D Consultant, Dimitrios Barakos. By collaborating with EMC test solution provider Rohde & Schwarz, we aim to find the most efficient solution for our clients. “

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.
