Fully Anechoic Chamber

Fully Anechoic chambers are widely used in both EMC and Antenna chambers for test application which required ground absorbers and fully lined Pyramidal wall absorbers. DMC FAC series can be utilized in Automotive, Military, Telecom and Defense test applications.

DMC-FAC-3M (3meter Fully Anechoic EMC Chamber)


DMC-FAC-3M is a Fully Anechoic Chamber or referred as FAC Chamber with 3 meter measurement distance. This chamber is similar to a semi-anechoic chamber, except absorbers are placed on ground plane as well to simulate a free space environment. It is made up of DMC-PAN series self-standing shielding, ferrite tiles and Polypropylene based hybrid absorbers on all walls, ceiling and floor.

DMC-FAC-3M can be used for fixed height pre-compliant radiated emissions as per CISPR-16-1-4 and compliant radiated immunity measurements as per IEC 61000-4-3
