The anechoic chamber can effectively eliminate external electromagnetic interference and a variety of reflective interference, which is mainly used to simulate free space environment for EMC testing on the EUT. Such 1m EMC testing chamber (7.8m x 7.8m x 4.2m), together with other auxiliary facilities, can meet the requirements of the various tests, such as CE102,CS101,CS114,CS115,CS116,RE102,RS103 of MIL-STD-461F. It can be used to guarantee the test environment of 1m EMC test.
