WebThe ESMW (eye symmetry mask width) test is unlike mask tests performed on NRZ eye diagrams. The ESMW mask, Figure 10, is a vertical stripe with width given by the minimum EW6 requirement centered on the midpoint of the middle eye, t center. A signal passes if the horizontal eye openings of all three eyes extend at least to the mask.
