QPHY-DISPLAYPORT VARIABLES
Test Mode
Specify whether to Acquire New Data or Use Saved Data for testing. Default is Acquire New Data.
Bitrate(s) to Use for Test
Specify whether to test the device under test at 1.62 Gb/s, 2.7 Gb/s or Both. Default is Both.
Lane Under Test
Specify the lane for testing. The choices are Lane 0, Lane 1, Lane 2 or Lane 3. Default is Lane 0.
SSC
Specify the state of SSC when running test. The choices are Enabled, Disabled, Both. Default is Disabled (Note:
some devices do not allow SSC to be disabled).
3.1 Eye Diagram Testing
Output Level to Test
Specify which output level to use for the Eye Diagram test.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
Pre-emphasis Level to Test
Specify which pre-emphasis level to use for the Eye Diagram test.
The choices are: 0 – 0 dB, 1 – 3.5 dB, 2 – 6.0 dB or 3 – 9.5 dB or any combination. The default value is 0dB.
3.3 Pre-Emphasis Level Verification Testing
Output Level to Test
Specify which output level to use for the Pre-Emphasis Voltage test.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
3.4 Inter-Pair Skew Test
Second Lane Under Test
Specify which lane to use as the second lane in the Inter-Pair Skew test. The choices are Lane 0, Lane 1, Lane 2,
Lane 3 or All. Default is Lane 1.
Output Level to Test
Specify which output level to use for the Inter-Pair Skew test.
The choices are: 0 – 400 mV, 1 – 600 mV, 2 – 800 mV or 3 – 1200 mV or any combination. For example, choose
“0, 1” to use 400 mV and 600 mV. The default value is 800mV.
Only Test At Highest Bit Rate
Specify whether to run the Inter-Pair Skew test on only the highest bit rate. The Compliance Test Specification
Rev. 1.1 only requires this test to be run at the highest bit rate; however, this option allows you to run this test at
both the High Bit Rate and the Reduced Bit Rate. This only applies when Bitrate(s) to Use For Test is set to
Both. Default is Yes.
3.5 Intra-Pair Skew Test
Output Level to Test
Specify which output level to use for the Intra-Pair Skew test.
