Because the right-hand slope of the tub does not provide additional information on
the jitter, the measurement's jitter display shows only the portion at the left-hand
side of the optimum sampling point.
The jitter histogram allows you to visually inspect the jitter components:
• Random Jitter (RJ)
• Deterministic Jitter (DJ)
• Estimated Total Jitter (TJ)
“Jitter Measurement Parameters” on page 260 describes how these components
are calculated.
A Gaussian marker is available in this view to help analyze the jitter components.
See “The Gaussian Marker” on page 237 for details.
Furthermore, the following parameters can be set on the View tab of the
Properties dialog box:
You can analyze for:
•
All Errors
To calculate the BER values from all bits/errors.
•
Errors if 0s Expected
To calculate the BER values if "0" is expected, but "1" received.
•
Errors if 1s Expected
To calculate the BER values if "1" is expected, but "0" received.
You can calculate measurement parameters for:
•
0 Errors
To calculate the parameters for 0 errors.
