The Jitter mode Duty Cycle Distortion (DCD) measurement is the result of one-level symbols having a different duration than zero-level symbols. One example cause of DCD is poorly matched transistors in an output stage. In Jitter Mode, DCD is a component of Data Dependent Jitter (DDJ). The other component is Inter-Symbol Interference (ISI). Duty Cycle Distortion, is derived from the Composite DDJ Histogram graph. It is the difference between the mean of the histogram of the rising edge positions and the mean of the histogram of the falling edge positions.
