Source Pre-emphasis Level Verification Testing 8
U7232A DisplayPort Compliance Testing Notes 79
Mask Scaling Option Sets the type of scaling performed on the mask for the eye test.
Mask Type Selects the type of mask to use for the eye test.
Interpolation (Debug
only)
Specifies whether to turn On or Off the Sin(x)/x interpolation filter.
Turning On interpolation may cause more peak-to-peak jitter.
Eye Diagram Mask
Movement (Debug only)
This field contains 4 options. (1) Find Passing Mode will automatically
search +/-0.5UI horizontally until no violation occurs, (2) Fixed Mask
will not be moving, it only report Pass or Fail upon test, (3) Find Biggest
Margin will search +/-0.5UI horizontally to find the maximum margin
of non-violation mask, (4) Manual mode will allow the user to move
the mask manually during the eye test,
Jitter Separation Settings
Jitter Separation Edges Sets the number of edges measured for the jitter separation test.
Bit Error rate Sets the bit error rate for the RJ/DJ measurements.
Transition Time
Transition Edges Sets the number of edges measured for the transition tests.
Transition VH Pattern
(Debug only)
Sets the pattern that represents a high or one voltage when three or
more ones are transmitted in a row.
Transition VL Pattern
(Debug only)
Sets the pattern that represents a low or zero voltage when three or
more zeros are transmitted in a row.
Upper Threshold (Debug
only)
Sets the upper threshold for the transition tests in percentage.
Lower Threshold (Debug
only)
Sets the lower threshold for the transition tests in percentage.
Non-Pre-emphasis
Level Edges Sets the number of edges measured for the level test.
Pre-empahsis Level
Pre-emphasis Edge Sets the number of edges measured for the level test.
Inter-pair Skew
Inter-pair Skew Edge Sets the number of edges measured for the inter-pair skew test.
Maximum Retries Sets the number of times that the application tries to measure the
inter-pair skew test before failing.
Spread Spectrum Clock (SSC)
SSC Acquisitions Sets the number of acquisitions taken to verify the SSC.
