·10-meter semi-anechoic chamber·
　　

The 10-m-method semi-anechoic chamber is a semi-anechoic chamber designed according to a test distance of 10m. It mainly consists of a main anechoic chamber, a control room and a power amplifier room (optional conduction test room). It is used for radiation immunity at a distance of 10m or 3m. Compliance test and radiated emission. The 10-meter method anechoic chamber is the most popular standard test environment. It is mainly used to meet the testing needs of large size electronic systems and the requirements of industry testing standards for some electronic products. It can also carry out 3-meter method testing. The quiet zone can be expanded to a diameter of 5 meters or even 8 meters or larger. It is widely used in IT products, household appliances, medical equipment, complete automobile and parts, large military electronic systems, industrial electronic systems, communications fields, etc. Electromagnetic compatibility testing. Typical inner shield size: 21m (length) × 12m (width) × 9m (height).

·3-meter method semi-anechoic chamber·
　　
The 3m method semi-anechoic chamber is a semi-anechoic chamber designed according to a 3m test distance. It mainly consists of a 3m method main anechoic chamber, an operation control room and a power amplifier room (a conduction test room can be configured). It is used for radiation immunity at a 3m distance. Degree test and compliance test of radiated emission. The complete darkroom system can cover multiple standards such as CISPR, EN, FCC, GB, and GJB, and has the ability to upgrade to a full-wave darkroom. It can be widely used in electromagnetic compatibility testing of IT products, household appliances, medical equipment, automobile parts, small military electronics, industrial electronics, communications and other fields. Equipped with special interfaces, special products can be tested, such as water meters, gas meters, electric energy meters, etc. Typical inner shield size: 9m (length) × 6m (width) × 6m (height).
