Predictive Modeling of the Effects of Skew and Imbalance on Radiated EMI from Cables
Proceedings of the IEEE International Symposium on Electromagnetic Compatibility (2007, Honolulu, HI)
Abstract
This paper provides an approach for predicting the effects of skew and imbalance on radiated emission of cables inside a commercial 19-inch rack-based cabinet. Scattering parameters (S-parameters) for two sets of cable assembly are measured with a four-port vector network analyzer (VNA) and converted into mixed mode S-parameters. Time-domain input signals with different slew rates and different amount of skew are transferred into frequency-domain using fast Fourier transform (FFT). The spectra of radiation emission associated with different inputs are then estimated.
