Anechoic Chamber for 10m testing on Telecommunication & ITE applications

This 10m Semi-Anechoic Chamber has been provided to a major Korean supplier of Telecommunication equipment for full-compliance radiated emission measurements in 10m test distance and for radiated immunity testing in the 3m test distance. The facility covers the whole frequency range 26MHz to 40GHz in accordance with the latest editions of International, US and European standards for EMC testing and site validation. Listing of the 10m site as FCC facility, getting European accreditation or VCCI recognition are both possible.

Typical EUTs (Equipments Under Test) are telecom equipment as well as information technologies equipment (ITE).

The chamber’s modularity for RF shielding and RF absorber lining is a proven advantage should the chamber ever be relocated or expanded.
