Abstract
The system includes a positioning system for mounting the circuit board to be tested and for mounting a sensor assembly. A control system registers the position of the sensor assembly relative to the circuit board to be tested and for moving the sensor assembly about the circuit board. The sensor assembly detects noise or other emissions generated by the circuit elements on the board. The noise emissions are separate from the operating signals of the circuit. The spectrum analyzer receives the emissions from the sensor assembly and produces frequency spectrum data over a selected frequency range with amplitude information. A processing system then compares the frequency spectrum information with frequency spectrum information from boards known to be good and provides information as to any differences and whether they are in an acceptable tolerance range.
