Steel, aluminium or copper?

Reverberation Chambers are made from different materials that influence performance and price. In this post, our reverberation expert, Dimitrios Barakos, and the EMC Solution Specialist at Rohde & Schwarz, Martin Randrup Villadsen, explain the key factors to consider when choosing the best materials for your testing solution.

The LUF1000 on Tour in Phoenix, Arizona

Why does Bas de Groot, our Director of Sales & Marketing, look so happy in this photo in Phoenix, Arizona, last week? Well, it’s the first day of the LUF1000 reverberation chamber on tour through the US.

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.

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.

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.

ISO 11451-5 RC method for EMC full-vehicle testing

In this preview of the 20-minute presentation from February 6 for Rohde & Schwarz, Comtest R&D Engineer Dimitrios Barakos outlines the latest updates of the new ISO 11451-5 Reverberation Chamber (RC) method for EMC automotive testing and highlights the basic steps required to enable full vehicle testing in a reverberation chamber.

SAC & FAR testing requirements per the CISPR16 standards

Is 3-metre SAC-testing in a 2-metre volume within standards? Our experts, Uliana Trucchi and Dmitriy Penkin, will inform you about the sometimes confusing chamber design criteria for major standards (CISPR16, CISPR25 and ETSI) in three different posts. This week: Semi Anechoic Chamber (SAC) & Fully Anechoic Room (FAR) testing requirements per the CISPR16 standards.

How to build a 10-meter semi-anechoic chamber?

Have you ever wondered how we build our 10-meter semi-anechoic chambers for radiated emission and/or immunity testing? In this video, we take you through the most important parts of this high-tech chamber we built for Force Technology (formerly known as Delta).

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.
