Event Description

Title:  Understanding SNDR and All that Goes Into It

Date:  April 16, 2019

Time:  8am PT/ 11am ET

Presented By:   Ransom Stephens, Author, Technologist, and Physicist

Sponsored by:  Rohde & Schwarz NA


Signal to noise and dispersion ratio is a complicated measurement that is required for transmitter compliance at high data rates. In this seminar, we’ll use the SNDR measurement as a lab to understand not only SNDR, but the important quantities that go into it and many other measurements: pulse response and how it relates to features of interconnects like transfer functions and impulse response as well as ISI (inter-symbol interference); waveform fitting, fit deviations, and signal distortion; and measurement of the steady state voltage and pulse peak. In the process, we’ll see exactly how SNDR compares electrical signal strength to the combination of random noise and harmonic distortion.

Who should attend:

Design, R&D, and test Engineers, as well as scientists and technicians who are interested in high speed serial data transmission including serdes, interconnects, circuits, and systems.

Presenter Bio:

Ransom Stephens, Ph.D. helps engineers advance to the highest data rates by teaching the concepts engineers need to design better systems, better serdes, and better ways to find problems and come up with solutions. Ransom started in basic research at labs in the US and Europe specializing in digging weak signals out of strong backgrounds. He brought those skills to high speed electronics in 1999 and invented new techniques for signal and noise analysis. Since 2005, when he started Ransom’s Notes, his seminars have helped thousands of EEs understand key nuances of their work. Ransom was named the 2017 Jim Williams ACE Contributor of the Year for content that advances engineering and design.He is also an accomplished book author: the novels The God Patent and The Sensory Deception both published by 47North, Amazon Publishing’s science fiction, fantasy, and horror imprint have each appeared on a variety of bestseller lists. His first full-length work of nonfiction popular science, The Left Brain Speaks the Right Brain Laughs, was published by Viva Editions in 2016. Ransom holds a Ph.D. in physics from the University of California.
