This video tutorial provides a comprehensive explanation of eye diagrams and how to interpret them for signal integrity analysis. Learn how eye diagrams are created and why they're valuable tools for engineers, then explore how common signal integrity issues like reflections, crosstalk, and loss affect eye diagram shapes. Follow along with detailed simulations that demonstrate each problem and its impact on signal quality. The tutorial also covers equalization techniques including CTLE, FFE, and DFE to improve signal integrity. Presented by Robert Feranec with guest expert Tim Wang Lee, this hour-long guide includes practical demonstrations using Keysight ADS software to help engineers recognize and troubleshoot signal integrity problems in electronic designs.
