Visualize Random and Deterministic Jitter

The doc_visualize_jitter model generates bipolar data, adds deterministic and random jitter, applies white noise, and displays the resulting eye diagram.

No Jitter Added

In the Channel Model with Jitter block, set the Deterministic jitter parameter to 0 and set the RMS jitter parameter to 0. When the model runs, the signal shows clean crossings as there is no jitter.

Deterministic Jitter Added

Set the Deterministic jitter parameter to 100e-12. Run the model to show the effect of the deterministic jitter. The separation between the two peaks in the jitter histogram indicates the deterministic jitter.

RMS Jitter Added

Set the Deterministic jitter parameter to 0 and set the RMS jitter parameter to 50e-12. Run the model to show the effect of the RMS jitter. The fuzziness around each of the crossings indicates the RMS jitter.

Deterministic and RMS Jitter Added

Set the Deterministic jitter parameter to 50e-12 and set the RMS jitter parameter to 20e-12. Run the model to show the combined effects of both jitter types.
