SER Floor Result
The Jitter mode SER Floor measurement is the predicted SER (Symbol Error Ratio) at intersection of the jitter and amplitude measurement locations within the eye. It accounts for both horizontal eye closure (jitter) and vertical eye closure (noise and interference). The SER floor is calculated by extrapolating the amplitude bathtub curve to the jitter measurement location and extrapolating the jitter bathtub curve to the amplitude measurement location. These floors are then added together to form the SER floor. If the floor is below 10E-18, the signal is considered error free.
For NRZ signals, the SER Floor measurement results are displayed in the Amplitude table. For PAM4 signals, the results are displayed in the Eye table.
