Abstract
A test procedure for deriving a radiated emissions transfer function has been developed. The function shows an empirical relationship between the harmonic content of signals on a balanced transmission line and corresponding electric field intensities at a given distance from the line. Test results indicate good correlation with this procedure below 50 megahertz. The transfer function may be used in conjunction with predetermined emission limits to provide the designer with a method of defining signal characteristics for complying with those limits.
A description of the test procedure and its range of application is discussed, focusing on a method of performing the test in a high ambient signal environment using automated test equipment.
