Example Results
The following illustration shows the resulting graph of a typical DUT
Output Timing measurement:
The following figure shows a typical jitter histogram with two peaks
indicating the presence of random and deterministic jitter:

Understanding the Jitter Calculation
After the output timing behavior of the DUT is measured, the Serial
BERT calculates the different jitter components:
To understand the RJ and DJ results, it is helpful to first understand
how the software generates the results:
