  • Hello Eric

    The USB and Ethernet test procedure for eye diagram requires a dedicated setup for measurement. Please refer to the documentation provided on the same by Tektronix and Agilent. We do our testing via 3rd party test houses.
  • Hi Amit,
    Thanks your suggestion.
    But I check Tektronix and Agilent in Taiwan and MCU need to some setup to creat eye signal output to Tektronix or Agilent machine measure.
    May I know how can to setup or define these register then can creat LAN or USB eye signal?
    Thanks.

  • Hello Eric

    For checking signal quality for Ethernet the Auto MDIX Link Pulse is sufficient. For testing USB you have to decide on the host or device function first. Based on that the setup changes.
  • Hi Amit,
    For USB testing for Host or Device, would you kindly provide relate document for our study reference?
    Thanks.

    It is the setup which differs.I know there is one from Agilent that does mention the setup. Unfortunately, I do not have it handy. I would suggest a Google search for the same.
