What does the transceiver TX transmit analog signal's waveform look like?

[1163032868@qq.com]

The transceiver TX transmitt analog signal out. What does the TX transmit analog signal's waveform look like? What does the pre-emphasized TX transmit waveform look like? Are there actual waveforms or eye diagrams? I only saw a received data's eye diagram on UG476.

Are you looking for an example or something else? 

Receiver eye is what we need to look at. IBERT can plot it if you need to investigate. For the transmitter side, you can measure this on a real board.
