ABSTRACT:
A printed circuit board assembly testing device includes a LISN device connected to a power source and to a test enclosure. The test enclosure includes a power supply and a communication port. A signal analyzer is interfaced to the LISN device. A circuit board assembly unit under test is positioned in the test enclosure. A controlling computer is interfaced to the communication port. The controlling computer includes a hard disk storage device having benchmark data stored therein. A communication bus interconnects the controlling computer to the signal analyzer. The unit under test is powered up and emissions data is observed which correlates to activity in the unit under test. The emissions data is compared to the benchmark data and a determination can be made as to whether the observed data meets the benchmark data within an acceptable tolerance.
