Main application areas
Test distance: The core feature of a 10-meter anechoic chamber is a test distance of 10 meters, which helps to reduce interference caused by reflection, thereby enhancing the accuracy and consistency of the test.
Structural composition: The 10-meter anechoic chamber for radio waves is typically composed of a main anechoic chamber, a control room, a power amplifier room, and other parts. The interior of the main anechoic chamber is lined with absorbing materials to absorb electromagnetic waves, prevent reflection and ensure the quietness of the testing environment.
Testing capability: It can conduct electromagnetic compatibility tests such as radiation emission tests, radiation immunity tests, and shielding effectiveness tests. In addition, it can also meet the requirements of various international and national standards, such as CISPR, IEC, GJB, etc.
Technical indicators: The 10-meter anechoic chamber has five key technical indicators, including shielding effectiveness, normalized field attenuation, field voltage standing wave ratio, field uniformity and environmental noise. These indicators directly affect the accuracy and reliability of the test.
Scope of application: The 10-meter anechoic chamber is suitable for radiation disturbance and immunity tests of various types of electronic equipment, communication equipment, automotive electronic equipment, industrial, scientific and medical equipment, etc.
