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.

Techniques for obtaining electromagnetic data from a circuit board

A method for selecting an I/O buffer. The method includes providing a plurality of I/O buffers. Each one of the plurality of I/O buffers has a different performance characteristic. Each one of the plurality of I/O buffers is coupled to a receiving device through a corresponding one of a plurality of transmission lines. Each one of the plurality of buffers is driven by a logic signal. Each one of the transmission lines produces a corresponding series of output logic signals. The plurality of output signals is observed. The method includes selecting one of the plurality of I/O buffers in accordance with the observed output signals.
