EMC Testing

From the time when automotive vehicles were essentially mechanical with spark ignition the only electrical system, through the many decades that brought the development of electrical, electronic and computer controlled automotive systems, the need for and methods of automotive testing have evolved along with the vehicles. At one time, electrical testing was sufficient. But with the dawn of the digital computer era, compatibility became a major issue. Those pesky clocked systems are inherently noise producers and are also subject to immunity issues.

Conducted emissions testing may be carried out on an Open Area Test Site (OATS) intended for testing radiated emissions, but it is not necessary to use an OATS and conducted emissions can be tested relatively easily, with high accuracy, in the comfort of your own building.

Released in May of 2011, GR-1089-CORE Issue 6 Electromagnetic Compatibility (EMC) and Electrical Safety requirements for Network Telecommunications Equipment has undergone a number of technical changes. We look at its substantial modifications and the potential impact on previously certified products.
