About Logic Analyzers

Logic analyzers are used to monitor and debug digital signals found in hardware circuits and systems. Most logic analyzers combine two devices: a logic state analyzer and a timing analyzer.

The state analyzer shows the logic-signal ones and zeros - but does not show glitches, clock skew, or signal path delays. The timing analyzer displays digital events on a time axis, similar to that of an oscilloscope. Essentially, the state analyzer is used to show what events happened on a data bus, while the timing analyzer shows when the events happened.

Traditionally, logic analyzers are thought of as a digital measurement tool. However, as data communication rates continue to increase, analog characteristics come into play. As such, you need to pick a logic analyzer as if you are buying an oscilloscope. For more information, see tips for buying digital test equipment.
