Abstract
An eye pattern measurement apparatus includes: an eye pattern monitoring device, performing first sampling on a data signal by sequentially using scan clock signals having different phases to obtain a plurality of scan data signals; and a data aligning device, connected to the eye pattern monitoring device, receiving the scan data signals outputted by the eye pattern monitoring device, performing phase-shift on the first clock signal to generate a synchronization clock signal, synchronizing the scan data signals with the synchronization clock signal, and outputting the synchronized scan data signals.
