Abstract
A method facilitates determining transmission loss in a transmission signal and adjusting a receiver setting of a receiver to compensate for the transmission loss. The method includes transmitting a transmission signal from a transmitter and receiving the transmission signal by a first receiver and a second receiver. The method includes digitizing the transmission signal by the first receiver at a first sampling frequency and digitizing the transmission signal by the second receiver at a second sampling frequency that is less than or equal to the first sampling frequency. The method includes generating a PAM-n eye diagram of the transmission signal by the second receiver using digitized signals digitized by the first and second receivers and adjusting an equalizer setting of a first equalizer of the first receiver using eye-opening information of the PAM-n eye diagram where the eye-opening information includes information for the transmission loss.
