Explanation of the Results
Additionally to the graphical results, the measurement provides some
information below the graph. You can also export the results to a .txt
file.
The following information helps you to interpret and document the test:
•
Result
of the test (passed or failed).
•
Date and Time
when the test was finished.
•
Margin
that was set for the test.
•
Further test
Conditions
like the selected test pattern and additional
jitter components.
