Principal Radiated Emission Specifications and Test Methods,This chapter is intended to make available only the essential radiated EMI limits as a complement to the design information provided in this book. These excerpts by no means constitute an acceptable substitute to the official texts, and any reader who is actually involved in testing should use the formal specification documents instead.

Generalities on Radiated Interference, typical sources of EMI until the 1960s were natural atmospheric noise, motor commutators, fluorescent lights, automobile ignition systems, and 50-/60-Hz overhead lines (unintentional sources), plus jamming by other authorized (and sometimes unauthorized) radio transmitters.

Fields Radiated by Nonsinusoidal Sources,on signal is not a pure sine wave but a repetitive signal with a known period and waveform. In both cases, the prediction process consists of first performing a Fourier analysis of the source signal, then treating each harmonic (or group of harmonics in a given bandwidth) as a sine wave for calculating radiation.

Printed Circuit Board Design,s” arrive at the inevitable conclusion that an in-depth look at PCB design would have saved thousands of dollars in testing, last minute fixes, and retesting, plus additional hundreds of dollars per unit, in hardware costs for shielding, gasketing, and so forth.
