3 Meter EMC Test Chamber

Panashield's 3 meter EMC anechoic chamber provides a test facility for performing full compliance radiated emissions and radiated immunity testing to various international standards. This proven design has excellent measured results well within the required +/-4 dB NSA levels specified in ANSI C63.4 and EN50147 part 2 (emissions) and is also fully compliant for EN61000-4-3 (immunity). The chambers are self-supporting and constructed using the versatile Panabolt modular panel RF shielding system and provide a high level of shielding integrity.
