Methods and apparatus are provided for monitoring a data eye associated with a received signal. A plurality of samples of the received signal are obtained for each unit interval based on a clock recovered from the received signal, to obtain an estimate of the data eye. According to one aspect of the invention, the samples are obtained substantially simultaneous to a decoding of the received signal. The collected data eye samples can optionally be processed, for example, to collect statistics on the received signal or to determine a distribution of the received signal.
