Source Eye Diagram Differential Tests 3
Agilent U7232A DisplayPort Electrical Performance Compliance Test Application 33
Test Condition
Bit Rate: all bit rates are supported.
Output Level: 800 mVolts.
Pre- Emphasis: 0 dB.
Test Pattern: PRBS 7.
SSC: If the device under test is able to operate either with SSC Enabled or
SSC Disabled then the device is tested for both conditions. If the device is
always SSC Enabled or always SSC Disabled then the device is tested in
its normal state.
Test Plan Check Mode Turn on test plan check mode to simulate the actual test plan run flow
without actual tests being run.
SSC Acquisitions Number of SSC cycle captured for SSC related tests. Maximum
number is 25.
Low Bit Rate SSC
Smoothing Points
Sets the number of smoothing points for SSC low pass filter when bit
rate is 1.62 Gbps.
High Bit Rate SSC
Smoothing Points
Sets the number of smoothing points for SSC low pass filter when bit
rate is 2.70 Gbps.
Memory Depth Sets the memory depth for acquisition
PRBS Validation Algorithm Settings
PRBS pattern checker
rule
Determine the rules applied to PRBS 7 Pattern detector. By selecting
Strict, test can only proceed with the correct PRBS 7 pattern only.

Eye Diagram
Eye Diagram Edge Sets the number of edges measured for the eye test.
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.
Eye Diagram Mask
Movement
This field contains 3 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 Margin
will search +/-0.5UI horizontally to find the maximum margin of
non-violation mask.
CTS Version for Eye Mask Set the mask file to CTS version 1.0 or 1.1
