Abstract: An automated circuit test system includes a magnetic sensor array configured to measure, at a plurality of locations, a magnetic field induced by a circuit under test. A circuit drive module can energize the circuit under test to induce the magnetic field. Optionally, the circuit drive module detects an electrical response from the circuit under test. Optionally, magnetic field data is combined with electrical response data prior to outputting the test result.

Abstract: According to embodiments, multi-axis magnetic sensors (magnetometers) are disposed in an array or a plurality of arrays. The magnetic sensors can be disposed on modules that form the array. The magnetic sensors can each sense a local magnetic field coincident with the respective sensors. Data corresponding to the local magnetic fields can be analyzed by a magnetic field analysis circuit and assembled to form an image corresponding to the sensed magnetic field(s). The magnetic field analysis circuit can output the image corresponding to near-field magnetic features.
