ETS-Lindgren FACT 3 Meter EMC Chambers, for Full Compliance Testing, offer semi-anechoic radiated emissions (RE) and fully anechoic radiated immunity (RI) compliance test capability for most international EMC compliance regulations. The chambers small overall size results from the use of hybrid absorber and ferrite tile, which require less volumetric space than traditional absorbers. FACT 3 chambers will fit in many existing structures, yet are large enough to perform 4 meter antenna scans above the ground plane. When installed with ETS-Lindgrens LoProTM or EuroProTM turntables, pit excavations for motor assemblies are eliminated. ETS-Lindgren FACT 3 chambers are the ideal choice when facility space is limited, but 3 m range testing is required.

Performance

ETS-Lindgren FACT 3 chambers achieve their broadband performance using a unique arrangement of hybrid and ferrite tile absorber. The design was modeled using the proprietary numerical electromagnetic software responsible for creating chambers that set new standards for anechoic performance.

Radiated Emissions Testing

ETS-Lindgrens FACT 3 chambers are designed to provide customers with more standardized solutions for different quiet zone diameters and performance options. This will provide users more flexibility to choose which solution works best for their individual needs. The available quiet zone sizes are available up to 2.0 meters in diameter. ETS-Lindgrens Fact 3 chambers can be used to perform full compliance testing for ANSI C63.4, FCC Parts 15 and 18, EN 50147-2, CISPR 11 / EN 55011, CISPR 16 / EN55016, CISPR 22 / EN55022, VCCI V-3/2003.04, SAE J551 and SAE J1113.

ETS-Lindgren guarantees that the performance of Normalized Site Attenuation testing according to ANSI C63.4, is 4.0 dB for STANDARD chamber, 3.5 dB for STANDARD PLUS chamber and 3.0 dB for PREMIUM chamber over the frequency range of 30 MHz to 1 GHz. The guaranteed sVSWR performance for frequency range of 1 GHz to 18 GHz is 6.0 dB, regardless which performance option is selected and better performance is achievable with chamber modifications.

Radiated Immunity Testing

ETS-Lindgrens FACT 3 chambers can also be used to perform full compliance testing for IEC 61000-4-3/EN61000-4-3, SAE J-551 requirements. At FACT 3 range lengths, field uniformity of 0 - 6 dB is achieved in the test aperture over the frequency range of 26 MHz to 18 GHz. At FACT 3 range lengths, test aperture is a vertical plane of 1.5 m x 1.5 m at an elevation of 0.8 m to 2.3 m above the ground plane and field uniformity of 0 - 6 dB is achieved in the test aperture over the frequency range of 80 MHz to 18 GHz, following the field uniformity test procedure of IEC 61000-4-3. Additionally, DuraSorb can safely withstand continuous field intensity of up to 200 V/m and intermittent field intensity of up to 500 V/m. This safely exceeds the field intensity requirements of most commercial RI tests.
