Dirt on your test chamber doors can cause serious performance issues, leading to unnecessary costs, downtime, or even non-compliance. For tempest-shielded facilities, it could even lead to a security breach. Our colleague Joëlle Driessen-Verkuijlen, who oversees our maintenance contracts, explains these risks and has a simple solution.

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.

‘Reverberation Chambers for Antenna and Communications Testing up to sub-THz Frequencies.’ This was the topic that Sander Bronckers from Technische Universiteit Eindhoven discussed at the Dutch Antenna Range Operator Meeting (DAROM) held at our Zoeterwoude (NL) office last Friday.
After Sander’s talk, we organised a tour of our Comtest Experience, where several colleagues demonstrated the latest skills and developments within our company. This was followed by lunch and a presentation by our R&D Specialist, Dmitriy Penkin, titled ‘Typical Shielding Effectiveness Levels of Microwave Absorbers in UHF & SHF Ranges.’
Eric van der Houwen, Antenna Test Engineer at European Space Agency – ESA, discussed the latest developments at the ESA-ESTEC Antenna Measurement Facilities. Bastian Balk, Market Segment Manager for Automotive Full Vehicle Antenna Test/EMC at Rohde & Schwarz, delivered a presentation titled ‘Performing OTA Measurements in an EMC Range—A Real or False Good Idea?’
