If you want to know more about FACT™ 5 CHAMBERS

ETS-Lindgren’s FACT™ (Free-space Anechoic Chamber Test-site) 5 Chambers offer the semi-anechoic radiated emissions (RE) and fully anechoic radiated immunity (RI) compliance test capability for most international EMC compliance regulations.

FACT 5 Chambers offer the ability to perform RE testing at a 5-meter distance while preserving the ability to perform full compliance testing of applicable 3-meter standards. Results obtained with 5-meter distance have better correlation to those obtained at a 10-meter distance than the ones measured at 3-meter distance. FACT 5 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-Lindgren’s FACT 5 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 3 meters in diameter.

FACT 5 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, CISPR 32/EN55032, VCCI V-3/2003.04, SAE J551 and SAE J1113. ETS-Lindgren guarantees that the performance of Normalized Site Attenuation (NSA) testing according to ANSI C63.4 with 5 meter test distance, 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 performance for Site VSWR (sVSWR) test per CISPR 16-1-4 (ANSI C63.4) for frequency range of 1 GHz to 18 GHz is < 6.0 dB, regardless which performance option is selected below 1 GHz.

Radiated Immunity Testing

FACT 5 chambers can also be used to perform full compliance testing for IEC 61000-4-3/EN61000-4-3, SAE J-551 requirements. At 3 meter test distance lengths, Field Uniformity (FU) of 0 to 6 dB can be achieved over the frequency range of 26 MHz to 18 GHz. The test aperture for FU 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, following the field uniformity test procedure of IEC 61000-4-3. Additionally, used absorber material 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 commercial RI tests.
