5M SEMI-ANECHOIC CHAMBER

Purpose The 5mSAC is developed with the focus on compliance testing emission and susceptibility at 5 m test distance. The complete system is designed for multi purpose use. International, US, European and various national standards are covered. The products that is able to be tested range from telecom equipment, household equipment, automotive components, Industrial Scientific and Medical equipment (ISM) as well as Information Technology Equipment (ITE). Listing of the 5mSAC as FCC facility, getting European accreditation of VCCI recognition is equally possible. The 5mSAC combines full conformity with standards, with an enhanced frequency range up to 18 GHz. Consisting of a fully modular system for shielding and absorbers, the installed chamber can be set up stepwise and adapted to upcoming normative. Emission Measurements Radiated emission measurements for compliance testing, development and quality control at 5 m distance are perfectly covered by the 5mSAC. The 5mSAC complies with ANSI C63.4 and CISPR 16-1-4 for a 3.0 m quiet zone diameter. In additional, the 5mSAC performs perfectly up to 18 GHz. Immunity Testing The 5mSAC features superior performance for radiated immunity testing. The accuracy achieved according IEC 1000-4-3 and EN 61000-4-3 in a 1.5 x 1.5 m plane at 3 m test distance fully complies with the a.m. standards. In additional, the 5mSAC performs perfectly up to 18 GHz. Radiation Radiated Emission The performance achieved according to ANSI C63.4 in a quiet zone diameter of 3 m at 5 m test distance is better than +/- 3 dB and the guaranteed values for site VSWR is  6.0 dB or better. Radiated Immunity The accuracy achieved according IEC 1000-4-3 and EN 61000-4-3 in a 1.5 x 1.5 m plane at 3 m test distance complies with the a.m. standards. As required 75% of the 16 points are within the 0 to +6 dB accuracy.
