What’s The Difference Between A Mixed-Signal Scope And A Logic Analyzer? by Agilent's Joel Woodward
While logic analyzers are typically used for single-shot applications, MSOs work across both single-shot tasks and applications that require the viewing of repetitive waveforms. MSOs have a simpler use model, as they’re usually limited to 16 channels or less, while logic analyzers come with many more channels. This limits MSO debugging to tasks that can be solved with up to four analog scope channels plus up to 16 digital channels, while logic analyzers can be used on debug tasks that require anywhere from a single channel up to hundreds of channels. That’s why users often think logic analyzers are more complex than MSOs.
