Abstract
A scanning device having a cable for connecting various parts is provided. A method is provided using a differential pair of clock generated signals to cancel each other, thereby reducing electromagnetic emissions. The differential pair is characterized by each being in phase with the other with regard to frequency, and each being the reverse of the other in amplitude.
