Tips & Trends for 2025: Inhouse pretesting for OEMs

In-house pretesting is a wise investment that saves time and money. In a series of five posts, our specialists share trends and developments for 2025. This week, Technical Consultant Uliana Trucchi will discuss the future of in-house pretesting for OEMs. Uliana: “More and more products contain electronics that require testing. Many OEMs use test houses […]

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.”

When is it time to acquire a FAC instead of a SAC?

When is it time to acquire a full anechoic chamber (FAC) instead of a semi-anechoic chamber (SAC)? After delivering 21 chambers and upgrades for the leading French test house, Groupe Emitech, we approached their Group Director of Purchasing and former Deputy Technical Director, Julien Joly, with this question.

Pre-compliant or full-compliant?

What stands higher on the agenda: the condition of equipment or people? The answer might surprise you! At the European Microwave Week in Paris this week, three of our technical consultants invited professionals to discuss this subject at our stand.

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.

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.
