Abstract
A method and apparatus for calibrating an equalizer. The method comprises the steps of defining one or more equalization parameters and calculating a bit error rate of a signal for one or more values of a first of the one or more equalization parameters by counting at least one of running disparity errors and incorrect symbol errors. A value for the first of the one or more equalization parameters which provides the lowest bit error rate is set.
