Claim Text:
1. A method for identifying an electrical noise propagation path through an object from a source of periodic electrical noise comprising the steps of: a) positioning an electric noise sensor of a noise measurement device at a selected area on the object, the noise sensor generating an output signal to the noise measurement device representative of the magnitude of electrical noise, b) generating a trigger signal in synchronism with the source of periodic electrical noise, c) connecting the trigger signal to the noise measurement device to initiate an electrical noise reading from the sensor by the noise measurement device, the noise measurement device generating an output signal as noise data, d) recording the noise data output from the measurement device associated with the location information of the selected area, e) moving the sensor to a different selected area, and f) reiterating steps a)-e), and g) identifying the noise propagation path based on the noise data output from the multiple selected areas of the object.
