EMC Center 10 m Method Anechoic Chamber
EMI measurements/EMS tests of large equipment and devices
The 10 m method anechoic chamber is equipped with a large-size turntable that has a 6 m diameter and can withstand a load of 4 tons, and it has a power supply capacity up to 24 kVA. In addition, it is possible to place related equipment, etc., in the turntable pit with a depth of 2.8 m using a lifter that can withstand a load of 120 Kg. This facility provides a one stop solution for measurement and testing of automobiles and large-scale equipment and devices.
In a radiated EMI measurement with a range from 30 MHz to 1 GHz, 2 antenna masts allow for effective measurement without antenna changes.
The facility can also handle EMI measurements with a range from 1 GHz to 6 GHz.

EMC Center 3 m Method Anechoic Chamber and Shielded Room M and M2
One-stop EMC measurement and assessment services for onboard devices
EMC Center's 3 m method anechoic chamber is a facility provided with an anechoic chamber and a shielded room, which are accredited EMC test laboratory for the automotive electronics devices. Equipment such as a special workbench (with a ground plane), which is different from that used for consumer equipment/devices, and an amplifier (1000 W output) for high impact radiated EMS are optimally located for EMC measurement of automotive electronics devices. In the shielded room attached to the chamber, measuring environments dedicated to electrostatic discharge (ESD) tests, bulk current injection (BCI) tests, etc., are available, and EUT can easily be set up, providing one stop solution for effective EMC measurement and evaluation of automotive electronics equipment/devices.
