Posters

Our colorful, informative posters introduce basic principles and applications of foundational techniques in signal integrity testing. They are about testing digital high speed communications electronics, and are intended for electronics engineers who need to verify compliance of their products.

Each poster is approximately 27” x 38” (68.5 x 96.5 cm), printed in full color on glossy, heavyweight paper.

Anatomy of Clock Recovery, Part 1 *

Clock Recovery Poster 1


 

“Clock recovery is a common part of many measurements, whether as part of the test setup of part of the device under test. We're going to look at clock recovery from a practical point of view, with emphasis on how it affects measurements… ”

 
 

Why is Clock Recovery Used?

 

How Does Clock Recovery Work?

Anatomy of an Eye Diagram *

 

Eye Anatomy Poster

PLEASE note that this poster IS NOT ABOUT THE ANATOMICAL EYE

 
"Eye diagrams are a very successful way of quickly and intuitively addressing the quality of a digital signal. A properly constructed
eye … often shows weaknesses in system design… "

What Makes Up an Eye?

What Does It Show?

Eye Diagrams and BER

Slicing the Eye

Testing Transmitters    

Transmitter Measurements
- Poor Return Loss / Poor Signal to Noise Ratio / Optical Measurements / Cable Loss

Testing Channels

Channel Measurements
- Bit Rates / Patterns / Distance
   

Testing Receivers    

Receiver Stressed Eye Measurements
- Inter-Symbol Interference (ISI) / Sinusoidal Interference (SI)
- Sinusoidal Jitter (SJ) / Random Jitter (RJ) / Bounded Uncorrelated Jitter (BUJ)

Jitter Measurements - How Deep is Enough?

Which Standards Use Stressed Eye?    
         

We receive a remarkable number of requests for the Eye Diagram Poster from opthamologists, opticians, medical students, etc. PLEASE NOTE: Our poster depicts the electronic eye diagrams used by engineers to test digital signals. It has absolutely nothing to do with an organic eye (human or otherwise).
