整车电磁兼容测试 整车EMC测试机构 整车性能检测
I 整车电磁兼容测试 Vehicle EMC Test
GRGT’s EMC laboratory is provided with a completely imported large 10-meter anechoic chamber of 29m (length) x 20m (width) x 11m (height). The turntable of the vehicle class anechoic chamber has both the diameter and the distance from the anechoic zone of 8m, which meets the requirements of a majority of vehicle tests. The tested object (EUT) can be of the maximum of 12m (length) x 4m (width) x 4.6m (height) and the maximum weight up to 30T.
This equipment set features high-precision automation and excellent performance, with the test software featuring instrument interchangeability, script technology and unified template, and the system drivers compatible with the German R&S receiver, German BORN amplifier, American AGILENT signal source, American AR amplifier and other mainstream imported equipment, as well as compatible with the domestic equipment such as sensors.
With nearly 160 devices special for EMI and EMS tests, the EMC laboratory has the electromagnetic interference frequency range of 25 Hz – 50 GHz and an electromagnetic sensitivity of the EMS maximum field strength up to 200 V/m. Therefore it can easily meet the requirements of CISPR, IEC, ISO and other standards, as well as the major OEMs’ standards.
