The need to deal with jitter is in-escapable, whether the market segment being addressed is tele-communications or high-speed I/O connections for data communications. In the first article of this series, we covered the basic definition of jitter, types of jitter and the principal measurement techniques, which we also called “vantage points.” In this article we begin by looking at specific instruments choices that are out there for observing and analyzing jitter. We then discuss jitter mea-surements at high data rates. In the final por-tion of this article we move on to the accuracy issues related to jitter measurements.
