Digital oscilloscopes, or digital storage oscilloscopes (DSOs) as they are often known, have replaced older analog oscilloscopes on most test benches. They are useful for analyzing transient events as well as high-frequency signals carrying complex modulation formats. Selecting a DSO is a matter of understanding some of the key performance specifications and how to compare them from model to model, and the link provides an article that reviews essential scope operating parameters, including those related to the instrument's display, time base, and acquisition/triggering capabilities.
