EMC & Compliance
Test with Confidence. Design for Compliance.
EMC testing requires more than individual instruments — it requires the right combination of measurement equipment, RF infrastructure and test environment. Magnetron Systems provides solutions for emissions, immunity and compliance testing, configured around applicable standards and the specific requirements of the application.
Solutions for EMC testing, from pre-compliance to advanced compliance environments.
Full Anechoic Chamber / Room (FAC / FAR)
The 3m Full Anechoic Chamber is designed to conduct comprehensive compliance measurements of radiated emissions and immunity at a 3-meter testing distance. This versatile EMC test facility is utilized for both commercial and telecommunications testing. The chamber features a robust construction, including a 2mm galvanized pan-type panel system, parallel-closing RF shielded doors, and polystyrene hybrid absorbers on the walls, floor, and ceiling. These elements work together to create a high-performance, controlled electromagnetic environment that meets international standards for immunity and emission testing.
