Upgrading an EMC chamber with new absorbers on old tiles
Can you upgrade an EMC chamber and keep the old, glued ferrite tiles? āItās possibleā, says Uliana Trucchi, one of our technical consultants. āSay 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 chamberās walls and ceiling. That is exactly what the people from Nemko in Germany asked us for the chamber upgrade in the photo.ā
The number of stirrer positions vs power
Testing time is valuable, so this post provides tips on optimising the number of stirrer positions in your reverberation chamber to fit your budget and test requirements. āThere is a delicate balance between the number of stirrer positions and the amplifier power for a given reverberation chamber,ā explains our R&D Consultant, Dimitrios Barakos. By collaborating with EMC test solution provider Rohde & Schwarz, we aim to find the most efficient solution for our clients. ā
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.
Dust-free absorbers on the AMTA 2024 in Cincinnati
No more dirty chambers! Our mission to create cleaner work environments brought us to Cincinnatiās AMTA 2024 Exhibition. In the photo in the middle, Vincent van de Vrie, the latest addition to our international technical consultancy team, is shown. He said he learned a lot from the many visitors to the three-day event.
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.
Big doors, a big challenge for packaging and transportation
How does a 4.2×4-meter door fit in the box in the photo? āItās not only a challenge for packaging but also transportation,ā explains Arjan Nederstigt. His colleagues Ron Ligtvoet, Ferruh Saribas, and Miguel Gobardhan join him in ensuring that all purchases are sent safely and soundly to our clients. One of the things that sets us apart from other manufacturers is that our doors are shipped in one piece after being thoroughly tested in our workshop so our team can install the doors fast and worry-free anywhere in the world. The challenge that comes with shipping completely assembled doors is their size.ā
An eye for perfection
According to our welding specialist Sebastiaan Koopmans, finishing an RF-shielded door requires special skills: āA regular household door fits into a wooden or metal frame. The āknivesā on our doors need to fit exactly into the copper āfingersā of the door frame after welding the parts together. Therefore, they must be sharp but not too sharp to wear the copper fingers. Just like a good kitchen knife. I test the welding edges of the door knives manually but safely: when they feel smooth enough, they get my green light.ā
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.

NLR-Arch setup measurements
Are radar cross-section measurements for absorbers still representative? No. Following the guidelines of IEEE1128, the NLR-Arch setup measurements are more representative. With the emergence of 6G, aerospace antennas, and automotive radar systems, antenna measurements above 40GHz are becoming more common, but they are still done worldwide in the old RCS way.
