Claim 2:
3. The method of claim 1, further comprising:
adjusting a reference voltage of a slicer from a first value used during measurements of the first eye height and the second eye height to a second value;
measuring, at the first sample timing, while using the second value, and by varying the DFE coefficient of the receiver, a third eye height while receiving the first data pattern;
measuring, at the first sample timing, while using the second value, and by varying the DFE coefficient, a fourth eye height while receiving the second data pattern; and
determining whether a first difference between the first eye height and the second eye height is greater than a second difference between the third eye height and the fourth eye height.
