Agilent Technologies J-BERT N4903B, User Manual, Page: 466 / 572

This displays the list of measured points. The list classifies the points with their
frequency, amplitude, and status. The status indicates whether the test passed or
failed at that point.
This contains the results as follows:
1 Test Configuration Details: gives the User Comments, Device Type, Last Test
Date, Model Number, Serial Number and Software Revision number.
2 Conditions: Pattern, Data Rate, Output Level, ISI Trace Number, Additional
Jitter, SSC, Target BER, Confidence Level, Relax Time and Margin.
3 Graph: Jitter Tolerance Graph.
4 Measured Points: List of points classified with their pass/fail status,
frequency, Periodic Jitter/Sinusoidal Jitter and Total Jitter without ISI.
5 Recommended Settings (only in the Compliance Report): Document, Note, Bit
Rate, Pattern, Level from Standard, Level at PG (recommended) and Additional
Jitter.
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:
•

of the test (passed or failed).
•
Date and Time
when the test was finished.
•
Margin
that was set for the test.
• Further test
