Abstract
An analysis procedure is described for use in determining the steady-state EMC margin in a spacecraft primary power distribution system. The analysis begins with estimates of broadband and narrowband emissions from each equipment unit. These are combined at the power source impedance to produce a bus ripple voltage spectrum which is then compared to the equipment susceptibility specification. Thus, the three variables of emission, susceptibility and source impedance are related in such a manner that specification tailoring can be performed and design tradeoffs can be evaluated.
