Unique features of anechoic chambers

‘EMC’ is acronym for ‘electromagnetic compatibility.’ EMC test chambers are designed to create an enclosure with an extremely high level of RF shielding attenuation against electromagnetic interference. A well-constructed chamber can absorb close to 100% of ambient emissions and reflect a minimal amount of internal radiation. This is achieved by lining the walls with absorbing material. For full anechoic chambers, the floor is treated as well.


Due to their unique nature, EMC test chambers allow their operators to test the radiated emissions and / or radiated immunity of, for instance, a new product or device. By shielding against all outside interference, you can accurately measure the strength of the electromagnetic field that is unintentionally generated by the equipment under test (EUT). An anechoic chamber’s primary application is to determine whether a product or device complies with emission and immunity limits defined in specific industry standards. However, depending on your industry, anechoic chambers can be used for testing according to a wide variety of EMC standards such as CISPR, IEC/EN, MIL-STD 461 and RTCA DO-160.
