Crosstalk
Aggressor Clock Divider
The clock divider for the aggressor lane pattern.
DPCD
Extra DPCD
Additional data that is written to the DPCD registers (format: “<register>=<value>, …” where <register> and <value>
are hexadecimal. For example “0909=01, 090A=FF”)
Extra DPCD Order
Defines the point when the extra DPCD (if any) is written to the DPCD registers.
Clearing DPCD Register
Before Changing Pattern
Defines the point when the DPCD (0x102) is cleared.
Jitter
ISI Amplitude
ISI amplitude applied during the test.
RJ Amplitude (RMS)
The RJ amplitude injected during the test.
Fixed SJ Amplitude(pk-pk
Fixed peak–peak SJ Amplitude injected during the test.
Fixed SJ Frequency
(Read-only) Fixed SJ Frequency used for the test.
Link Training
Max. injected error count
during Error Counter Test
The maximum number of errors that are injected during link training to test the Error Counter.
Pattern
Sequence File
The name of the sequence file that is used for testing. Make sure this property is in sync with the Link Quality Pattern
Hint.
SSC (Spread Spectrum Clocking)
Use SSC
SSC is applied for testing with the specified frequency and amplitude.
SSC Frequency
The frequency of the SSC modulation.
SSC Amplitude
The amplitude of the SSC modulation.
Voltages
Tested Lane Eye Height
Calibrated eye opening used during the test.
Aggressor Lane Voltage
Calibrated aggressor signal differential voltage used during the test.
Start Differential Amplitude
First amplitude value of the output generator.
Differential Amplitude Step
Size
Differential voltage step size for the test. At every step, the output voltage is decreased by this value.
