摘要：A series of pulses may be driven down each drive channel, which creates a seriesof composite pulses at the output of the buffer. Each composite pulse is a composition ofthe individual pulses driven down the drive channels. Timing offsets associated with the

drive channels may be adjusted until the individual pulses of the composite pulse align orclosely align. Those timing offsets calibrate and/or deskew the drive channels,

compensating for differences in the propagation delays through the drive channels. Thecomposite pulse may be feed back to the tester through compare channels, and offsetsassociated with compare signals for each compare channel may be aligned to thecomposite pulse, which calibrates and/or deskews the compare channels.
