I think they probably work ok, but since they need a pc running windows of some sort, I have always looked at them as a solution in search of a problem. A problem I have not encountered because when all you have is a 100mhz dual trace scope, all problems are solvable with it, just like if all you have is a hammer, everything looks like a nail. :) OTOH I have little knowledge of how to properly use a logic analyzer, and that is a more complex digital field I can't comment on other than I have found hundreds of logic problems with a dual trace scope of adequate bandwidth, adequate usually being defined as at least 50x the clock rate of the circuit. In either usage here, you will have to lug around the pc too, they are not standalone devices. Generally, and unless you are designing drivers from scratch, quite meaningful information can be had from a DS201. Its not that fast, but neither are the outputs of a pc headed for the machines control drivers, stepper or servo. And if you don't wad up the probe(s) but have a suitable container for them, the scope itself will fit in your shirt pocket, but I'd use button down flaps to keep it secure when you bend over to do something else. Falling in a coolant catch tank would not be good for it. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
