  • Method and apparatus for monitoring electromagnetic emission levels
    Patent number: 5006788
    Abstract: Electromagnetic emission from a printed circuit board is monitored by energizing the board while it is located adjacent an array of electromagnetic emission measuring probes. The probes are successively addressed and currents induced in the probes are measured at a receiver. A memory map of the electromagnetic emission as a function of board position is generated and is displayed together with the circuit board layout so that regions of high emission level can be identified in the circuit. Each probe of the array is a series connected pair of wire loops, the planes of the loops being perpendicular to each other and to the plane of the array.
    Type: Grant
