Protocol Analysis in a Scope

摘要

Oscilloscopes continue to use increasingly sophisticated protocol analysis capabilities. Protocol triggering and decode application options are available on newer scopes and can be added to most recently purchased scopes. As multigigabit serial links are deployed into embedded designs, the choice of a traditional protocol analyzer vs. outfitting a more general-purpose oscilloscope with protocol analysis becomes blurred.rnFor guidance on what to choose, ask yourself the following questions: What is the primary tool I want to use for debugging? Do I have the potential need for debugging across both physical and protocol layers'? How can I evaluate protocol analysis in a scope for the specific serial bus of interest?rnScope vendor websites and datasheets contain helpful information on features, pricing, and availability.
