Patent ID: 8374231

Claim:
An equalization simulator with training sequence detection for use in an oscilloscope generating a digitized waveform record from acquiring samples of an analog waveform signal from a serial data link comprising: an input signal processor receiving the digitized waveform record and producing a processed digitized waveform record having channel effects of the serial data link removed; a sequence detector receiving the processed digitized waveform record and generating a training sequence; an equalization adapter receiving the digitized waveform record and the training sequence with the equalization adapter having means for recovering a clock from the received digitized waveform record having a clock rate equal to the bit rate of the analog waveform signal, a re-sampler receiving the digitized waveform record and the recovered clock and generating a re-sampled digitized waveform record according the sampling bit rate of the analog waveform signal using the recovered clock signal, means for aligning the re-sampled digitized waveform record with the received training sequence to generate an training sequence aligned with the re-sampled digitized waveform record, and means for receiving the re-sampled analog waveform and the aligned training sequence and generating equalizer taps; and an equalizer receiving the equalizer taps and the digitized waveform record and generating an equalized digitized waveform record.
