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.
Product Description
The main purpose of a 3m full anechoic chamber is to perform full compliance measurements of radiated emission and immunity at 3m test distance. The 3m full anechoic chamber is a multi-functional EMC test facility for commercial and telecom testing. The combination of the pan-type 2mm galvanized panel system, parallel closing RF shielded doors and polystyrene hybrid absorbers on the walls, floor and ceiling creates a high performance controlled electromagnetic environment that complies with international immunity and emission test standards.
