If the results of a Fast Total Jitter measurement are displayed, only the appropriate
parameters are compared and flagged:
•
Phase Margin
•
Optimal Sample Delay
•
Total Jitter Peak to Peak
•
Fast Total Jitter Uncertainty
Other pass/fail limits may be enabled but are ignored.
In the tabular view, each of the calculated values will be marked with an
icon if it failed the test.
The following illustration shows a DUT Output Timing/Jitter measurement that
has failed the criterion for the phase margin.
