How to Set Up an Eye Diagram on an Oscilloscope - Scopes University - (S1E3)

An introduction to eye diagrams

In this episode of Scopes University, you’ll learn some of the basics of what makes up an eye diagram and why you want to use one to verify the physical layer fidelity of your clock or serial data. Erin steps through how to quickly and easily set it up on the oscilloscope. You’ll start out by understanding the bitrate by using the built-in automatic measurement. Then, you will learn what clock recovery is and understand how this is used for an eye diagram. Lastly, you’ll set up the eye diagram in less than a second.

Tune in for future Scopes University episodes covering more oscilloscope capabilities to see how you can test more efficiently!

The digital storage oscilloscope we used:
(The Keysight InfiniiVision 6000 X-Series Oscilloscope)

This oscilloscope supports the most applications of any InfiniiVision oscilloscope, including power analysis, jitter measurements, and built-in dual arbitrary waveform generators. It features a 12.1 inch touch screen display and dedicated vertical control knobs for each channel. This all makes it the value leader in price for performance.

Scopes University is hosted by Erin East and Melissa Spencer. The video series covers when and how to use different applications and capabilities of the InfiniiVision and Infiniium oscilloscopes. You’ll gain familiarity with features that will help you save time in your measurement, further your analysis, and deepen your insight.

Old problem: understanding eye diagrams
*watches video*
*looks up price for the scope*
New problem: not enough money on bank account

I knew what an eye diagram looked like, and I've seen them on scopes, but now I know what they mean and what they are used for, thank you!

How do I calculate the bitrate of my Signal if I don't have your measurement function? Is it just two times the frequency of my Signal?

[IncapaxPlays]

As someone learning a lot about data transfer recently I think I need a scope or logic analizer but I'm not sure if it's worth half a year or more of saving money.

I have the same model scope and use it for eye analysis of serial data. The part where I lack confidence is in the probing of high-speed signals. The probe is the N2752A 6Ghz, but I don't know how much the probe is disturbing the signal. I only have one of these probes at the moment so I cannot double up the probe loading to visualize.

I can understand the basics of eye diagram.Thanks

[khalidjj]

Nice video..
How can we do the same with a DPO 4054B scope. Thanks

[carloscarosella]

What is used to analyze the frequency and diagram in the oscilloscopy?

[timpeng]

Hey, i am wondering if I can measure the eye diagram of clock signal itself? Or it doesn’t make sense at all since the clock signal is the base for triggering.

[bringinghomethebananas]

How do people that don't have a $22, 000 scope do an eye diagram?

[andig]

Why didnt u show the physical connection??

[amitm]

Nice explanation. You can remove the name university because most universities are at-least 2 to 10 years behind current technology in engineering.

Great video but there's usually a lot more swearing and cursing involved.
