<I can't agree with that. OK, so a logic analyser will monitor a lot of

I'd also point out that if the LA in not connected into the system
correctly it can by virtue of ground loops and other things like the leads
actually induce problems. Seen that occur to people. same for scopes too!
I'm not saying they are bad but for some stuff you can end up looking for
the forest between the trees. the best example was a multibus design bring
up another engineer was doing and the board didn't do what was predicted
and of course it was surrounded with scopes LAs and even probes... the
problem...
8086 asm
MOV AH,Ah ( was supposed to move the immediate value x0A to
register A high byte!)
Them trees can hurt when the land of you.
