Faster transitions contribute to a cleaner eye diagram. Signal Amplitude: Measure the difference between the maximum and minimum voltage
For a given eye opening, eye amplitude is defined as the difference between the mean value of the symbols above and below the eye opening. It is usually calculated in a narrow window around the
Eye Amplitude, measured in Amplitude Units (AU), is defined as the distance between two neighboring eye levels. For an NRZ signal, there are only two levels: the high level (level 1 in figure) and the low
You can combine eye diagram analysis with histogram measurements to get further insight into your design. The 9400 series with Picosample 4 can

In telecommunications, an eye pattern, also known as an eye diagram, is an oscilloscope display in which a digital signal from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rate is used to trigger the horizontal sweep (x-axis). It is so called because, for several types of coding, the pattern looks like a series of eyes between a pair of rails. It is a tool for the evaluation of the combi
