The anechoic chamber is mainly used to simulate free space environment for EMC testing, and it can effectively eliminate external electromagnetic interference and a variety of reflective interference. Such 3m EMC anechoic chamber, can used to accomplish the standard 1m-distance test as MIL-STD-461F, GJB151/152A, and 3m EMC standard test for civil electronic and electrical products as civil standards GB9254-1998, GB/T 17626.3-1998.
