International pioneering and stirrer design

In the world of stirrer designs for reverberation chambers is a lot going on. In the photo, our friends from Rohde & Schwarz Singapore and Hyundai Motor Company (ķ˜„ėŒ€ģžė™ģ°Ø) are visiting our company due to their interest in RVC stirrers. They get an introduction to our new development of sinuous stirrers, production facilities, and the reverberation chamber we made for the Technische Universiteit Eindhoven (in the photo).

Renovation and upgrades of EMC and Antenna test chambers

In this article, Senior Technical Consultant Uliana Trucchi explains what can be wrong with outdated test chambers from the 1990s or earlier. Do they still meet the current technical specifications, the latest editions of EMC test standards, and modern health and safety requirements?

Blue lines for safety and efficiency

If you ever received a shipment with boxes missing, you know how annoying that can be. To avoid that, our production manager AndrƩ Oostdam prepared a part of the Comtest warehouse for a safe and efficient area for shipment preparations.

Single-floor absorber
set-ups

A single-floor absorber set-up for radiated emissions AND radiated immunity instead of two different set-ups? Yes, that is exactly what we did for our client, Aesys, in Italy. They raised the need to optimise the space and the test setup time, so we started brainstorming about a solution that could still meet the requirements.

Clean hands at EMC Fest in Livonia (MI)

We were surprised by the feedback we got on our cleanliness proposition at EMC Fest in Livonia (MI) last week! ā€œSome people came back to our table several times!ā€ says our local sales representative in Michigan, Tony Oliverio. What happened?

The scaleable amplifier/ chamber dilemma solved

Did you know that amplifiers for reverberation testing chambers can be scaleable? Picking the proper amplifier is a major factor in the total costs of a new chamber. That is one of the reasons we teamed up with Rohde & Schwarz, the global market leader in EMC and immunity test solutions, including solid-state RF Microwave amplifiers in various frequency bands/bandwidth combinations and power classes.

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.
