ALTER TECHNOLOGY expands EMC Test Capabilities

This chamber increases the capacity to carry out EMC and radio tests. It can make measurements at 5 meters, which allows larger devices to be tested, like satellite equipment, new space or railway control stations, plus achieving ISO7 cleanliness conditions due to absorbers capabilities.

ALTER TECHNOLOGY expands EMC Test Capabilities

Free-space anechoic chamber test-site,  5 meter EMC test chamber with auxiliary combined Amplifier and Control Rooms. 

The new Free-space Anechoic Chamber Test-site 5 meter (FACT5) is composed by a semi-anechoic chamber or extensible to full-anechoic chamber thanks to dedicated additional ferrites and absorbers, auxiliary equipment room for supporting the equipment under test (EUT) and control room from which the measurements or radiation of electromagnetic disturbances are performed. 

FACT5 has nominal internal shield-to-shield dimensions of 11.6m L x 7.3m W x 5.6m H which allow a 5 meter length measurement distance making use of its turntable withstanding up to 1.5 T of EUT weight and the state-of-the-art antennas and mast combination. The outsized chamber also allows for testing large products up to 2.5 m height, which provides greater flexibility for our customers and meets the requirement for the standard CISPR 16, ECSS-E-ST-20-07c, MIL-STD-461F, or RTCA-DO-160G for EMC and Radio Spectrum Matters among others.

Performance parameters regulated by CISPR-16-1-4 have being tested exceeding basic expectations of NSA ±4.0 dB from 30 MHz to 1 GHz and SVSWR of ≤ 6.0 dB from 1 GHz to 18 GHz. Thanks to previous validation due to extensive use of building information modelling during the design phase, the best materials were selected such as hybrid broadband absorber substrates with rigid, closed cell foam and ferrite enabling to meet cleaning requirements for space campaigns. Also, the thorough tracing during the building phase to assemble the metal structure, doors and panels provide high shielding effectiveness, maintain electrical continuity, providing RF attenuation of from 120 dB at low frequencies up to 70 dB at 40 GHz.

On top of that, FACT5 is provided with an artificial vision system that grants the monitoring of EUT behaviour while is being tested (flashing lights, movements, optical character recognition, etc), particularly when susceptibility to radiated EM fields are being performed. The test facility is rounded off with the last high-end test equipment, supply and communication interfaces and our experimented laboratory technicians.
