Abstract
A system is configured to obtain electromagnetic data from a circuit board. A set of sensing locations resides in a plane which is substantially parallel to the circuit board. The system includes a probe, a robotic assembly coupled to the probe, and a controller coupled to the probe and the robotic assembly. The controller is configured to move the probe to various sensing locations (e.g., a two-dimensional grid of sensing locations) and collect electromagnetic data from these sensing locations. The controller is further configured to provide an electromagnetic data output based on the collected electromagnetic data. The controller is further configured to direct the probe (or an adjacent probe) to emit electromagnetic interference at these locations in order to determine the effect of such interference on circuit board operation.
