the ultimate faultfinding device isn't made by Tektronix, Agilent or
Lecroy, it doesn't come from RS components, Farnell, or Digikey. As
I've said many times before, it's called a brain :-).
Back in the day, techs didn't get to use Logic Analyzers much in any
case. They were targeted as development tools, not for troubleshooting,
and only the high mucky-muck engineers had them. They were too
expensive (always in the five figures, usually the mid five figures) for
mere 'troubleshooting' and really not that well suited to such pursuits.
A Logic Analyzer is for things like developing a Data General mini.
First thing would be
to connect a logic analyzer to see if the CPU is still running
a programm in ROM or not.
Hi
What is it with logic analyzers. Why not just an
oscilloscope. In most cases, one can be farther along
with an 'oscope in finding what is wrong by the
time one can get an analyzer connected and setup.
I've only had one time that I ever needed an analyzer
and even that time, it didn't work well because
of the complexity of the problem ( design not failure ).
I'll admit that I've often thought of making one
of those address compare circuits to trigger the 'scope
but by the time I'd get serious, I'd found the problem.
Am I alone here or does everyone else think that an
analyzer is the ultimate tool?
