EMC Technologies commissions a new semi-anechoic chamber

EMC Technologies has commissioned a new semi-anechoic chamber (SAC) in Sydney at its Seven Hills laboratories. The SAC is NATA-accredited as an alternative (indoor) Open Area Test Site (iOATS). It is suitable for the testing of most products requiring EMC compliance for radiated emissions up to 40 GHz including most CISPR standards, MIL-STD461/2, DO160F and regulatory requirements such as C-tick/RCM, FCC, IC, CE and VCCI.

The chamber was designed and installed by EMC Technologies’ engineers. It is said to be the largest such chamber in Sydney. It features: a 2 x 2 m quiet zone (maximum EUT size), a bore-site antenna mast and a 3 or 5 m test distance 3 x 3 m access doors and 10 m of usable space. These important features allow convenient indoor testing of large items for both Class A and B limits (for most standards) without the inherent problems associated with travelling and testing at open area sites. Testing at 10 m is carried out at the Colo OATS or at EMC’s Melbourne iOATS if outdoor testing is not suitable.

The iOATS is compliant with: CISPR 16-1-4 for a 2 x 2 x 2 m test volume (quiet zone) to 18 GHz;  FCC, IC, VCCI, CISPR 11, 12, 13, 15, 22 (Class B), 24, 25 and 32; immunity standards IEC/EN 61000-4-3, ISO 11451-2, ETSI/EN wireless standards and many others.

Other features include: 3 x 3 m access door, three-phase power, 700 kg/2 m turntable and 2 x 2 x 2 m test volume that allows compliant testing of large racks/systems; bore-site antenna mast adjusts antenna angle for direct line of sight to EUT as height is swept from 1 to 4 m; 10 m of useable space allows versatility such as indoor antenna radiation pattern measurements.
