966 Fully Anechoic Chamber

Radiated Emission (RE) mainly refers to the phenomenon where energy is emitted from a source into space in the form of electromagnetic waves and propagates through space, causing interference to equipment in the surrounding environment.

The 966 Fully Anechoic Chamber Electromagnetic Compatibility (EMC) Laboratory features a 3-meter anechoic chamber, uniquely capable of converting between fully and semi-anechoic configurations. The testing system inside the chamber is provided by the renowned German company R&S (Rohde & Schwarz) and comes equipped with a comprehensive suite of emc testing software. Specifically for mobile phone clients, we offer specialized testing instruments and corresponding supporting software for mobile phone spurious emissions. Additionally, the complete set of EMS (Electromagnetic Susceptibility) equipment in the laboratory is supplied by HTEC, ensuring stable performance and accurate data.
