System Tx

This configuration will set up for System Tx compliance testing using the CLB3. Predefined
configurations exist for testing 1, 4, 8, and 16-lane devices. Tx Compliance tests are performed
using the SigTest software. SigTest uses binary waveforms (.trc) from the oscilloscope, embeds
the reference channel, and applies the CTLE/DFE filter. The wizard will instruct you to capture
both data and clock from the system board.

The test items are:

Min Transition Eye Height

Min NonTransition Eye Height

Composite Eye Height

Mean UI

Max Pk-Pk Jitter
