For the test instrument, the clock signal of the signal is first recovered from the signal to be tested, and then the eye diagram is superimposed according to the clock reference, and finally displayed. Figure 1: Formation of the Eye Diagram 2. Information contained in the Eye Diagram For...
This argument sets the plotting symbol, line type, and color for the eye diagram. The format and meaning of the symbols are the same as in theplotfunction. For example, the default value'b-'produces a solid blue line. Data Types:char|string ...
This example shows how to useeyeDiagramSISystem object™ to measure properties of a sampled data signal originating from laboratory data and check eye opening compliance against an eye mask. Save the waveform data in aStandard File Format, or a format for which a reader is available on theFi...
Eye Diagram (Removed) Display eye diagram of time-domain signal expand all in page In R2025a, eye diagram analysis, such as measurements, histograms, and bathtub curves, has been removed from the Eye Diagram block. For more information, see Version History...
(a) A perfect square eye diagram, (b) a closed eye diagram due to bandwidth, fiber impairments, noise, and timing jitter. The Q-factor (q) is also an important system parameter widely used in long-distance optical transmission system design. It is defined as the electrical signal-to-...

Eye-diagram mask testing can also be performed on CAN FD signals using a 3000T or 4000 X-Series oscilloscope. CAN FD eye-diagrams are based on the first 10 bits of the FD phase from all CAN FD frames. However, this application note is focused on eye-diagram mask testing on “classic”...
set up the eye is press “auto setup”. You will see in just a few seconds that the eye diagram has begun to form. Over time, you will be able to see if there is any jitter or anomalies in your signal. Generally, you will want to let the test run for a longer period of time...
Time interval between data values in theYarray. Default value: 1.0 Y The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively. ...
