This anechoic chamber is designed in strict accordance with the electromagnetic compatibility (EMC) testing requirements of GJB 151C (Chinese military standard) and MIL-STD-461G (U.S. military standard). It is suitable for conducting electromagnetic emission (EMI) and susceptibility (EMS) tests on military equipment and subsystems. The chamber provides a high-precision and highly reliable testing environment for military organizations, defense laboratories, and supporting suppliers, ensuring that equipment meets both Chinese and U.S. military standard certification requirements.
The standard anechoic chamber specifications listed below can accommodate a 3-meter-long test bench, and the chamber size can also be customized according to user requirements. The standard configuration includes the test bench and its corresponding quick grounding system.
