142 Agilent U7232A DisplayPort Electrical Performance Compliance Test Application
16 Source AC Common Mode Noise Single-Ended Tests
Test Condition
Bit Rate: all bit rates are supported.
Output Level: all output levels are supported.
Pre- Emphasis: all the pre- Emphasis settings are supported.
Test Pattern: PRBS 7.
SSC: If the device under test is able to operate either with SSC Enabled or
SSC Disabled then SSC Disabled will be selected. If the device is always
SSC Enabled or always SSC Disabled then the device is tested in its
normal state.
Two single- ended signals are probed independently, acquired
simultaneously and compared.
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.
Expert Mode Turn on the expert mode for looser pre-requisite checker.
Single-ended Tests
AC Common Mode
AC Common Edge Sets the number of edges measured for the AC common mode test.
Interpolation Specifies whether to turn on or off the Sin(x)/x interpolation. Turning
On interpolation may cause more peak-to-peak jitter.
Filter Specifies whether a high pass filter, low pass filter or no filter is
applied before the measurement. Interpolation is turned off if any filter
is chosen.
Cut Off Frequency Sets the Cut Off Frequency if a Filter is applied.Specify in correct
format; xMHz, xkHz or xHz.
