Abstract
A protocol and bit rate independent test system for detecting bit errors on a digital communications channel regardless of format or rate, comprising a receiver for receiving an input, a clock recovery unit, a threshold sampling circuit for providing at least two threshold detectors for respective two sampling points including at least one static sampling point positioned proximate to the center of an eye pattern and at least one dynamic sampling point, the output of which are sampled by the recovered clock and if the signal passes between the thresholds, an error signal is generated and counted.
