5.0 GT/s Signal Quality Tests
The following tests are run on the 5.0GT/s compliance pattern with 3.5dB of de-emphasis and
also with 6.0dB of de-emphasis.
• Mean Unit Interval
• Min Time Between Crossovers
• Data Rate
• Max Peak to Peak Jitter
• Total Jitter at BER of 10e-12
• Deterministic Jitter Delta-Delta
• Random Jitter (RMS)
• Minimum Transition Eye Voltage
• Maximum Transition Eye Voltage
• Minimum Non Transition Eye Voltage
• Maximum Non Transition Eye Voltage
• Minimum Transition Eye Voltage Margin Above Eye
• Minimum Transition Eye Voltage Margin Below Eye
• Maximum Non Transition Eye Voltage Margin Above Eye
• Maximum Non Transition Eye Voltage Margin Below Eye
• Mask Violations Transition Eye
• Mask Violations Non Transition Eye
These tests use the SigTest analysis package that is built into the oscilloscope software. The
SigTest settings are set to be the same as when the SigTest software runs independently.
• Bit Rate = 5.0 GHz
• BER = -12
• Eye Type = Monochrome
• UIsPerEye = 1.67UI
• Jitter Filter Settings
