Methods of Representations
There are two methods of representing the eye diagram:
• Waveform
• Contour
Waveform
Waveform is the shape, and form of a signal. The waveform graph shows the
periodical variation of voltage against time.
The waveform in the Serial BERT is similar to the one in the oscilloscope. In this
case, the waveform initially gives a coarse, but quick picture of the signal quality;
while the ‘smooth waveform’ quickly generates a high resolution graph. The
waveform is displayed in an incremental way, showing the coarse picture quickly,
and then refining it further.
