The EMC laboratory

RISE has seven test facilities for EMC testing and will soon be opening its eighth. Currently, the largest is the Faraday test hall. Next in size are Tesla, Edison, Weber, Hertz, Maxwell and Fourier, each with its own special set-up. January 2018 will see the opening of Awitar, which, like Faraday, is designed for testing vehicles, but has even greater flexibility for different types of test item.
Awitar – state-of-the-art chamber for vehicle testing etc.

Awitar is designed for testing vehicles and large machinery. It will be bigger than Faraday and can be used for testing all types of test item weighing up to 70 tonnes. The design of the floor and wall absorbers means that the chamber also satisfies all requirements for measurements at a distance of 10 metres, for testing telecommunications equipment, for instance.

Faraday – special chamber for vehicle testing

Like Awitar, our other large hall, Faraday, was specially designed for vehicle testing in close conjunction with the Swedish automotive industry. In addition to the testing of vehicles, we have decades of experience in testing forestry machinery, heavy earth-moving equipment and military vehicles.

Faraday can accommodate vehicles and other test items weighing up to 60 tonnes. Field strengths in excess of 100 V/m can be applied at up to 18 GHz, which is a requirement of some vehicle and military standards. Radar pulses of several kV/m can be generated in the L-, S-, M- and X-bands. The test turntable incorporates a four-wheel chassis dynamometer having a sophisticated control system, and there are two more rollers outside the turntable. Systems such as GSM, GPS, DAB, etc. can be emulated during testing.

Tesla – a versatile test chamber

Tesla is a semi-anechoic chamber for small and medium-sized test objects.  It is used for such applications as immunity testing of IT and industry products up to 18 GHz.  In terms of size, it can accept objects up to the size of cars. 

Emissions are measured at 3 m or 5 m, as specified in the most important test methods.  The chamber has FCC approval and approval for type-testing of automotive components. 

The absorbent material is a combi-absorber, which guarantees good test conditions over a wide range of frequencies.  The chamber's performance has been measured by an independent third party, and its performance confirmed as exceeding the requirements of the standards.  Areas for conductive testing and ESD testing are provided outside the chamber. 

Edison - with substantial measurement facilities

Edison duplicates most of the facilities in Tesla.  The measurement distance is 3 m, and the laboratory can contain test objects up to the size of equipment cubicles.  Both Edison and Tesla are fully automated in order to deliver short set-up and measurement times. 

Weber - for automotive components

Weber is the latest addition to our test chambers.  Although designed primarily for CISPR25 and ISO 11452-x series testing of automotive components, it can also be used for testing industrial products. 

The chamber includes equipment for testing hybrid components and systems such as DC power units and high-voltage DC filters. 

Hertz - designed for high frequencies

Hertz is a fully anechoic chamber that has been designed for emission measurements in accordance with modern standards as well as for normal immunity testing.  It is also suitable for ERP measurements of radio transmitters.  All surfaces are covered with high-performance absorbers for antenna measurements and probe calibrations from 30 MHz up to high in the microwave region.  The facility also includes facilities for conductive tests and ESD testing.

Maxwell - for outdoor measurements 

Test site Maxwell is suitable for antenna calibration.

Maxwell is an open area test site with a ground plane and 10 m measurement distance. With its good performance, it is suitable for antenna calibration.

Fourier - for research

The Fourier test laboratory is not a shielded room, but a laboratory that is used mainly for research but also for some testing.  It includes facilities for measurements in a reverberation chamber for frequencies down to about 400 MHz.
