DDj Versus Bit Position The DDj versus Bit Position view in M1™ eliminates random jitter by using repetitive copies of the pattern within the acquisition, leaving only data dependent jitter. This measurement provides insight into the data dependent jitter versus pattern location. This helps you pinpoint data-dependency problems. The view plots the Min (yellow), Max (blue) and Mean (green) Time Interval Error (TIE) corresponding to that edge's position in the repetitive bit pattern (gray).
