EMC & EMI


Electro Magnetic Competence & Electro Magnetic Interference

Garc has a state of the art facility to conduct EMI/ EMC development and certification tests on vehicles and automotive electrical/electronic components. The facility includes two semi anechoic chambers, one for heavy vehicles / cars and another for two wheelers, three wheelers and components. A separate component test lab is also available for conducting tests on electronic sub assemblies. The test systems have capability from 20 MHz up to 18 GHz for radiated emissions and from 10KHz to 18 GHz for radiated immunity. Both the chambers shall be used for compliance tests as per AIS 004, CISPR and ECE R10 and other standards. Developmental tests as per OEM’s requirements shall also be conducted at our facility.
