This procedure covers the recommended testing techniques for the determination of radiated immunity of an automotive electronic device. This technique uses a Tri-Plate Line (TPL) operating over a frequency range from 10 KHz to 1000 MHz. This technique is limited to components which have a maximum height of equal to or less than 1/3 the height between the driven element and the outer, ground plates. A TPL, a variation of a TEM cell design, is constructed without sides to the cell. The primary advantage to the use of the TPL as opposed to a TEM cell is that its construction permits large devices to be placed within the cell with their associated cables attached without special feed through ports or adapters as required for a TEM cell. The lack of sides which would be found in a TEM cell permits easy routing of the cables to and from the Equipment Under Test (DUT). The TPL does not have a serious problem with fields reflected from the side walls as does with the TEM cell.
