Abstract:
1. An apparatus comprising: a ground plane coupled to a chassis, a transmission line comprising a first and a second shielded line shielded by the ground plane, wherein a first end of the first shielded line is coupled to a first port and a first end of the second shielded line is coupled to a second port of a connector, a micro-strip coupled to a second end of the first and the second shielded line, wherein the micro-strip is to detect an electric field and a magnetic field induced by current steps injected into the chassis, and a measurement system coupled to the connector, wherein the measurement system is to determine the electric field and the magnetic field detected by the micro-strip, wherein a plurality of changes in the electric field is caused by a current step flowing through the chassis over a short time period.
