Method and system for identifying an electrical noise propagation path

A system for identifying an electrical noise propagation path through an object from a source of periodic electrical noise comprising:

• a noise measurement device having an electric noise sensor positioned at a selected area on the object, the noise sensor generating an output signal representative of the magnitude of electrical noise,
• a trigger generator which generates a trigger signal in synchronism with the source of periodic electrical noise,
• the trigger signal from the trigger generator being connected as an input signal to the noise measurement device to initiate an electrical noise reading by the sensor, the noise measurement device generating an output signal as noise data,
• a recorder which records the noise data output from the measurement device associated with the location information of the selected area,
• wherein the sensor is moved to different selected areas on the object collecting electrical noise readings for each selected area on the object, which are recorded by the recorder,
• a processor which determines the electrical noise propagation path based on the noise data from the multiple selected areas of the object.
