3m Compliant EMC Test Chamber

For users who want to perform compliant emissions and immunity tests at a distance of 3m


Global EMC’s SAC-3m-C is a semi anechoic 3m EMC compliant test facility. This chamber is the perfect solution for users who want to perform compliant emissions and immunity tests at a distance of 3m. The self-standing steel structure and modular steel shield enables a fast and efficient construction process. A combination of high performance GF 102 ferrite tiles and pyramidal hybrid absorbers are used to create optimum performance.


Testing facility for performing compliant radiated emissions and immunity testing. The chamber meets the anechoic performance requirements of NSA +/- 4dB from 30 MHz to 1 GHz and SVSWR in microwave frequency. The chamber is designed to perform 4 meter high antenna scans for emissions.
