Test and Measurement of High-speed Communications Signals

Posted November 20th, 2009 · Please leave a comment · Webcast


My colleague Greg Le Cheminant has posted his popular course, Test and Measurement of High-speed Communications Signals. It’s a video version of the short course he’s been teaching at OFC each year since 2002.

There’s a free five minute preview and a link to the complete course at that web site.


The ability to accurately characterize signals and waveforms is an essential element in the development and manufacturing of high-speed communications components and systems. This course will emphasize measurement tools and techniques to characterize signal quality and how well it is maintained when transmitted through an optical system. It will focus on three measurement areas: bit-error-ratio (BER) analysis, oscilloscope waveform analysis with emphasis on the eye diagram and jitter analysis. The basics for each measurement type will be covered, gradually building to the more difficult aspects of measurements, including common measurement problems and their solutions. Results from tests performed on actual components and systems using BERTs, high-speed sampling oscilloscopes and jitter test sets will be presented. The course will emphasize research and development and manufacturing measurements of components and subsystems instead of installation and maintenance test.
