Cable EMI Characterization Using a Reverberation Chamber
July 8, 2009 |Estimated reading time: Less than a minute
The design and manufacturing of data cables to be used in high-performance applications presents a number of challenges as the application speeds increase. Previous work by these authors has shown the potentially large impact of differential delay skew in the generation of common-mode noise and therefore EMI. This paper, written by IBM's Joseph C. (Jay) Diepenbrock and Dr. Bruce Archambeault and presented at DesignCon 2008, follows that work by examining various methods for measuring the shielding effectiveness of such cables and discussing practical considerations involved in building and characterizing a reverberation chamber for such measurements.
