Yes. The MP1026A can perform Duty Cycle Distortion (DCD) measurements. DCD is a component of the Data Dependent Jitter. Duty Cycle Distortion is a measure of the time separation between the rising edge and falling edge at the 50% level of the eye diagram. To measure the DCD, the 50% level of the edges is calculated using the same histograms that are used in the Rise Time and Fall Time measurements (take the center of the 20% to 80% measurement). The DCD is then calculated using the following equation: DCD % = 100 x [Time difference between rising and falling edges @ 50% level / Bit period]   The DCD value is given as a percent of the Bit Period. To determine the DCD value in time (ps), divide the % value by 100 and multiply by the Bit Period (in ps).
