Alpitronic’s room with 1500V / 1000A filters
23 meters long, 15 meters wide, and 9 meters high, with a turntable that has an 8-meter diameter. Technical Consultant Uliana Trucchi explains what makes this room so unique.
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).
To understand Comtest, you need to know about Hein
This is Hein de Groot, the founder of Comtest and the father of Bas and Rik. You need to know about Hein to understand our company, so we asked Bas and Rik to share more about him.
Prevent radiation leakage through the door!
The door in your test chamber can be the primary cause of radiation leakage, according to our service mechanic, Edwin Van Der Ploeg: “I have inspected and cleaned hundreds of RF-shielded doors, and I noticed that the ones used daily tend to open and close more difficult due to dust and dirt. Some even start to make a lot of noise when you open them. If so, you should act quickly,” Edwin advises.
After six years the closed-cell absorber with the perfect tip
Rik de Groot, the Managing Director of Dutch Microwave Absorber Solutions, and his team spent six years developing a closed-cell absorber with the perfect tip. But why is it so difficult to achieve this?
Could Automotive industry profit from reverberation testing
Could the automotive industry profit from reverberation testing in the future? At the EMC-ESD event 2023 of FHI Industriële Elektronica in Vianen on November 21, our R&D Engineer Dimitrios Barakos will give a 20-minute talk on EMC measurement in reverberation chambers.
Re-inventing the microwave absorber models!
Our sister company, Dutch Microwave Absorber Solutions, invested six years in developing a pyramid-shaped absorber from expandable polystyrene (EPS).
Welding the edges of a test room
“Welding the edges of a test room door is like sharpening a samurai sword”, says Sebastiaan Koopmans. And we believe him because he is our welding, eeh sifu. You should understand that finishing an RF Shielded door requires special skills.
What happens when a test engineer is born in Gouda
What happens when a test engineer born and raised in Gouda finds cheese in a small shop in Estonia? This is Peter de Wilde. He has seen most of Europe performing calibration measurements for us for 15 years now and knows the challenges of calibration on location like no other: “I have a base kit for all the testing I do, but the circumstances differ greatly! I try to ship the testing gear with the chamber elements or separately if the chamber is already being built. I send it on pallets, but sometimes I must bring three cases into the plane!”
More representative absorber reflectivity measurements
Is the radar cross-section method for absorber reflectivity measurements still representative? No, following the guidelines of IEEE1128, the NLR-Arch setup measurements are more representative of determining RF absorber characteristics.
