This procedure covers the recommended testing techniques for the
\ndetermination of radiated immunity of an automotive electronic
\ndevice. This technique uses a Tri-Plate Line (TPL) operating over a
\nfrequency range from 10 KHz to 1000 MHz. This technique is limited
\nto components which have a maximum height of equal to or less than
\n1\/3 the height between the driven element and the outer, ground
\nplates.<\/p>\n
A TPL, a variation of a TEM cell design, is constructed without
\nsides to the cell. The primary advantage to the use of the TPL as
\nopposed to a TEM cell is that its construction permits large
\ndevices to be placed within the cell with their associated cables
\nattached without special feed through ports or adapters as required
\nfor a TEM cell. The lack of sides which would be found in a TEM
\ncell permits easy routing of the cables to and from the Equipment
\nUnder Test (DUT).<\/p>\n
The TPL does not have a serious problem with fields reflected
\nfrom the side walls as does with the TEM cell. This permits its use
\nto frequencies above that of a TEM cell of the same physical size.
\nNote that although the construction of the TPL limits generation of
\nuniform electric and magnetic fields to frequencies below 500 MHz,
\nexperience has shown that the TPL may be used at frequencies up to
\n1 GHz and still provide reasonable and repeatable test results.
\nThis may only occur if the test setup requirements (i.e., DUT plus
\n1 meter of cable) and characterization procedures, delineated in
\nthis SAE Standard permits its use to frequencies above that of a
\nTEM cell of the same physical size. Note that although the
\nconstruction of the TPL limits generation of uniform electric and
\nmagnetic fields to frequencies below 500 MHz, experience has shown
\nthat the TPL may be used at frequencies up to 1 GHz and still
\nprovide reasonable and repeatable test results. This may only occur
\nif the test setup requirements (i.e., DUT plus 1 meter of cable)
\nand characterization procedures, delineated in this SAE Standard
\nare followed.<\/p>\n
The lack of side walls also means that the TPL must be used
\nwithin an RF shielded enclosure to prevent RF energy, radiated from
\nthe TPL from interfering with near-by electronic devices. To
\nprevent potential resonances and reflected waves within the
\nshielded enclosure from distorting the fields produced within the
\nTPL, the test chamber walls and ceiling must be lined with RF
\nabsorbing material. These issues are discussed in greater detail in
\nthe body of this are followed.<\/p>\n

CAUTION–Hazardous voltages and fields exist on and near the TPL
\nwhen the equipment is energized. Test personnel should ensure that
\nno one is in the test chamber during a test. It is the intent of
\nthe EMI committee to withdraw this document in five years unless
\nthere is a demand to retain the document<\/p>\n","protected":false},"excerpt":{"rendered":"
