A measurement method, comprising acquiring, by a measurement apparatus, a plurality of at least three measurement segments, wherein each measurement segment is acquired at a corresponding measurement time, and wherein time information is gathered, wherein the time information allows to derive ratios of time differences between said measurement times; and playing back the plurality of at least three measurement segments, wherein each measurement segment is played back at a corresponding playback time, and wherein, using said time information, the playback times are chosen such that ratios of time differences between said playback times correspond to ratios of time differences between the corresponding measurement times.

A method of operating an oscilloscope is disclosed. The method comprises providing a bit stream comprising pseudo-random data to an oscilloscope across a data path characterized by sufficient signal degradation to prevent the oscilloscope from reliably triggering a sweep of an eye pattern based on receiving the pseudo-random data; inserting a predetermined sequence of bits into the bit stream at predetermined periodic intervals to open the eye pattern sufficiently during each of the periodic intervals to permit the oscilloscope to trigger the sweep of the eye pattern; and generating the eye pattern based at least in part on the pseudo-random data and excluding the predetermined sequence of bits from the sweep of the eye pattern. Oscilloscopes configured to trigger according to a predetermined system of bits at predetermined intervals are also disclosed.
