We asked two of our technical consultants what they learnt from three days at EMV 2025 in Stuttgart last week. Vincent van de Vrie (photo centre): “Some very interested people were exploring the EMC chamber options we displayed at our booth.
We have a scoop! This week, we will unveil four 3D models of our latest worry-free EMC chamber solutions at the EMV exhibition in Stuttgart (D). In the photo, Marc Le Roy from our sales team is preparing to install the models at booth 417 in Hall C2.

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.

Advancements in wireless communication technologies will increase the demand for passive intermodulation (PIM) testing. In a series of five posts, our specialists share trends and developments for 2025. This week, R&D Engineer Dmitriy Penkin (in the photo on the left) will discuss PIM testing in 2025.
Dmitriy: “PIM can reduce receiver sensitivity and, in some cases, may even completely inhibit communication. Recognising and mitigating the PIM problem is essential for increasing system reliability and reducing operation costs. In our R&D department, we study the sources and causes of PIM and design solutions to detect and solve it.”
How can telecommunication companies prevent PIM from happening in the future? Dmitriy: “Base stations and mobile equipment OEMs must secure reliable communications. Accurate PIM measurements and related troubleshooting campaigns are only possible in an anechoic chamber that is properly designed and characterised by very low PIM levels, such as the chamber in the photo we built for a large telecom network provider. At our Comtest Engineering R&D department, we apply extensive and expanding knowledge to equip our clients with a chamber solution designed as ‘PIM-free’: such a test chamber has an aluminium shielding enclosure since we aim to replace all ferromagnetic materials with non-magnetic alternatives. Think also of specific aluminium or plastic screws, wooden test benches, special rails and more. Last but not least, we continuously work on optimising microwave absorbing material to ensure minimal nonlinearities within the anechoic chamber.”
