CISPR 25 Chamber

Driving Automotive EMC Compliance with Accuracy

Our EMC Chambers are engineered to provide optimal environments for electromagnetic compatibility (EMC) testing, ensuring your devices meet international standards for electromagnetic interference (EMI) and electromagnetic susceptibility (EMS). Whether for R&D, compliance testing, or pre-certification, our chambers offer unparalleled precision and reliability.

CISPR 25 Chamber

CISPR 25 is an international standard that provides guidelines for assessing radio disturbances in vehicles, boats, and electrical devices. Our CISPR 25 chamber is a dedicated testing facility aimed at evaluating the electromagnetic compatibility of automotive components and systems. This chamber is specifically designed to adhere to the criteria outlined in the CISPR 25 standard, which emphasizes the measurement of radio disturbances in vehicles.

High-Performance Anechoic Lining - Perfectly tuned for EMC Chambers

Ferrite Tiles & Absorbers – The walls and ceiling of the test chamber are meticulously outfitted with cutting-edge gapless Hybrid Pyramid absorbers and Ferrite tiles. These Pyramidal absorbers are carefully engineered to facilitate a seamless transition from the exceptional performance of the Ferrite tiles at lower frequencies to the Pyramidal absorbers at higher frequencies.

Hybrid absorbers, in contrast to microwave absorbers, utilize a ferrite underlayer and are an established solution for both semi and fully anechoic chambers tailored for EMC testing applications. The patented design provides the EMC absorber with numerous benefits compared to other options. They serve as an excellent alternative to foam absorbers!

Shielding Effectiveness - IEEE 299 / EN 50147-1

Shielding Effectiveness is the cornerstone of reliable EMC testing. It ensures that electromagnetic chambers provide a controlled, interference-free environment necessary for accurate and repeatable measurements. By isolating test setups from external noise and preventing internal signal leakage, SE upholds the integrity of test results, supports compliance with industry standards, and enables the development of robust, interference-resilient technologies. Tekiknow Chamber provides a Shield effectiveness of 100dB, with a performance Chamber reaching 110 dB. This performance Chamber is typically utilized in high-performance applications and specific high-frequency requirements.
