EXCEPT that a logic analyser will usually only handle digital (ie logic) levels - ie each channel can be either high or low only. Some analysers allow glitch catching and analog levels to some extent but these are getting fancier than the average logic analyser. Being purely digital makes it possible to have a much higher channels x bandwidth product than a scope of the same price. Results are stored to a buffer which allows signal analysis and tracing after the event. Also triggering in various signal conditions. Some, eg HP, make mixed signal scopes which have both analog and logic input parts. RM -- http://www.piclist.com hint: The PICList is archived three different ways.
