3-Meter Anechoic Chamber

SAC-3M is a semi-anechoic chamber designed for a 3-meter test distance. It mainly consists of a 3-meter main anechoic chamber, an operation control room and a power amplifier room, and is used for radiation immunity tests and compliance tests of radiation emissions at a 3-meter distance. A complete anechoic chamber system can cover multiple standards such as CISPR, EN, FCC, GB, and GJB, and has the ability to be upgraded to a full-wave anechoic chamber.

Main application areas

It can be widely used for electromagnetic compatibility testing in IT products, household appliances, medical equipment, automotive parts, small military electronic products, industrial electronic products, communication fields, and more. After adding special interfaces, special product testing can be carried out, such as water meters, gas meters, electricity meters, etc.
