        A logic analyzer is a simplified oscilloscope with many more =
channels. All
a logic analyzer cares about is one or zero, anything in-between is =
shown as
either one or zero. While a scope is usually only a few channels, logic
analyzers can have thousands of channels. Also logic analyzers can have =
VERY
complicated triggering conditions, while with a scope you are usually
limited to an edge with some sort of delay.

        Logic analyzers are indispensable when it comes to debugging =
complex
digital circuits, usually when dealing with many wires (i.e. a PCI bus).


        Unfortunately they are often a little on the expensive side. If =
you're
interested in building one for yourself have a look at the one I built:
