Automotive EMC Chamber Brochure

We have partnered with Albatross Projects (AP), a German ISO 9001 certified anechoic chamber manufacturing company to offer a wide selection of fully and semi-anechoic chambers around the world.

AP originated from Siemens AG who began manufacturing shielded rooms as far back as 1930. With over 10,000 rooms installed worldwide, AP have the expertise and experience to deliver the highest quality chambers wherever you are.

Base Anechoic Chamber Models

We offer several base models to suit a wide array of testing requirements. Contact us if you have any questions or would like to discuss customization options.

CISPR 25 Chamber

CISPR 25 automotive component testing

Our RF-shielded semi-anechoic chamber is ideal for fully compliant CISPR 25 testing requirements.

The chamber is specifically designed for CISPR 25 and ISO 11452-2 measurements of automotive components with maximum dimension up to 1-meter.

CISPR 25 Vehicle Chamber

The CISPR 25 Vehicle Chamber is a larger version of the base CISPR 25 chamber and allows fully compliant vehicle level testing according to CISPR 25.

The new testing methods outlined in CD 301 calls for hybrid absorber due to their strong performance in the low MHz range.

Our chambers meet stringent requirements for site attenuation and the new long-wire test methods.

5 and 10 Meter Automotive Testing Chambers

EMC Testing CISPR 25 ISO 11452

The large automotive chambers for 3 m, 5 m and 10 m test distances are classical semi-anechoic chambers (SAC), the most popular alternative test sites for EMC measurements and tests.

Their structure and configuration are ideal for large and heavy EUTs and are commonly equipped with a chassis dynamometer.
