Eye diagrams: The tool for serial data analysis

The eye diagram is a general-purpose tool for analyzing serial digital signals. It shows the effects of vertical noise, horizontal jitter, duty cycle distortion, inter-symbol interference, and ...

Eye-Diagram Analysis Speeds DDR SDRAM Validation

Double-data-rate synchronous dynamic random access memory (DDR SDRAM) physical-layer testing is a crucial step in making sure devices comply with the JEDEC specification. The ultimate goal is to ...

Eye Diagrams, Bathtub Curves, And Bit-Error Rates

On an oscilloscope's eye-pattern diagram, the distance between peak deterministic and random jitter amplitudes (the unit interval, or UI) is often called a "bathtub," which functions as a ...

Logic analyzer creates multichannel eye diagrams

Purists may argue that you can't create true eye diagrams by using the eye-scan mode of Agilent's new 68-channel, 300/600-MHz (state), 1.2-GHz (timing)/4-GHz (timing-zoom), deep-memory logic-analysis ...
