• Anechoic chamber equipped with chassis dynamo for EMC test of actual automobile that allows conducting EMC test in the state where all electronic devices of the automobile are functioning.

In EMI test, measurement can be fit at dark noise performance.

Chassis Dynamometer (CHDY）is the equipment of compliance with automobiles possible to simulate driving conditions on board. Installation can be done at anechoic chamber.
Transportation from compact vehicles to large passenger cars, compliance with various automobile measurement standards in emission test, measurement can be done at the standard of public announcement from Ministry of Land, Infrastructure, Transport and Tourism in fiscal year 2011.
We developed CHDY for anechoic chambers. It is superior to less electromagnetic from CHDY. Electromagnetic from automobile can measure exactly.
