84 Agilent U7232A DisplayPort Electrical Performance Compliance Test Application
9 Source Pre-Emphasis Level Differential Tests (Normative & Informative)
Test Condition
Bit Rate: all bit rates are supported.
Output Level: all output levels are supported.
Pre- Emphasis: all the pre- Emphasis supported settings are subject to the
constraints listed in Table 3- 12 of the DisplayPort Standard.
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.
Vswing Edge Sets the number of Edges used when performing the Vswing
measurement. The Vswing value is used to ensure that the waveform
is displayed as large as possible in the waveform viewing area.
Increasing this value increases the test run time but improves the
repeatability of the measurement.
VTop & VBase Edge Sets the number of edges required when making the VTop and VBase
measurements.
Expert Mode Turn on the expert mode for looser pre-requisite checker.
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.
Source Differential Tests
PreEmphasis Level
PreEmphasis Edge Sets the number of edges measured for the Pre-Emphasis Level test.
