Abstract
A field detection device such as a micro-strip portion of a transmission line may detect an electric field and a magnetic field induced by current steps injected into the chassis coupled to a ground plane. The shield portions of the transmission line may be coupled to a first and a second port of an I/O connector. A measurement system coupled to the connector may determine the electric field and the magnetic field detected by the micro-strip. The measurement system may determine the electric field and magnetic field based on computing the sum and difference of the signals provided by the first port and the second port.
