Variable Crossover
You can change the crossover point in range 30% … 70% of the NRZ signal
separately for each channel. The variable crossover is used to artificially close
the eye pattern, which simulates distortion.
The crossover adjustment is not calibrated except for the 50% point.
Example The figure below shows the normal and complement output with the crossover
point set to 50% and 70% respectively.
