ABSTRACT:
A positioning system is provided for mounting a circuit board or device to be tested, and for mounting a sensor assembly, the positioning system having the capability of moving the sensor assembly in three dimensions. The sensor assembly is positioned on the mounting assembly such that it is not in contact with the circuit board under test. The sensor assembly in operation samples the electromagnetic field emanating from the circuit under test and converts those signals into a representative electrical signal in a digitized format. A processing system compares the measured values from the sensor assembly with reference values from the same point in a circuit known to be good and provides an indication to the user as to whether the difference therebetween is within an acceptable range or outside thereof.
