ETS-Lindgren FACTTM 5 Chambers offer the ability to perform radiated emissions testing at a 5 meter distance. While not required by any current standard, measurements made at a 5 meter distance have better correlation to those obtained at a 10 meter distance. While permitting 5 meter testing, these chambers preserve the ability to perform full compliance testing of applicable 3 meter standards.

The chamber's small overall size results from the use of ETS-Rantec hybrid absorber ferrite tile, which require less volumetric space than traditional absorbers. ETS-Lindgren FACTTM 5 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-EMCO LoProTM or EuroProTM turntables, pit excavations for motor assemblies are eliminated.

ETS-Lindgren FACTTM 5 chambers achieve their broadband performance using a unique arrangement of hybrif 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.
At 3 and 5 meter range lengths, ETS-Lindgren guarantees a Normalized Site Attenuation (NSA) better than ± 3.5 dB deviation from theoretical NSA within the quiet zone, over the frequency range of 30 MHz to 1 GHz. The quiet zone at 3 and 5 meter test distances is cylinder up to 2.0 meter in diameter, following the volumetric test procedure of ANSI C63.4-2000.

Anticipating tomorrow's requirements, the FerroSorbTM hybrid and FT series ferrite tile absorbers used in this chamber to also guarantee NSA performance of better than ± 3.5 dB deviation from theoretical NSA using the test method defined in ANSI C63.4 (2000) at the extended frequency range of 1 to 40 GHz.
Radiated Immunity Testing
ETS-Lindgren's FACTTM 5 chambers can also be used to perform full compliance testing for IEC 61000-4-3/EN61000-4-3, ENV 50140 and SAE J-1113 requirements. At 3 meter range lengths, field uniformity of , + 6 dB is achieved in the test aperture over the frequency range of 26 MHz to 1 GHz. The test aperture is a vertical plane 1.5 meter x 1.5 meter at an elevation of .8 meter to 2.3 meters above the ground plane, following the field uniformity test procedure of IEC 61000-4-3.

Anticipating tomorrow's requirements, an optional absorber treatment package is available which permits radiated immunity testing at frequencies up to 40 GHz with , 6 + dB field uniformity, following the test procedure of IEC 61000-4-3.

Additionally, ETS-Rantec FerroSorbTM 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.
