WebThis method can produce a good eye unless the pattern length divided by the divide ratio yields an integer - for example a 128-bit pattern viewed with a ÷4 clock. In this case, the trigger signal will coincide with the same bits in the pattern each time while consistently missing other parts of the pattern - leading to an incomplete eye.
