OK, let's not bash FNIRSI too much.?
?
I have their DPOX180H 180MHz two channel scope.? It works very well, and for the price, it does a very respectable job.? It hasn't failed me at all in any of the QMX related signal tracing I have done.? I don't expect it to behave like a scope costing 2x or 10x as much.? It would be nice if it went lower than 50mV per division, but most cheap scopes don't.? And while it is very good up to 120MHz or so, it does suffer somewhat in performance at its spec'd 180MHz.?? I do wish it had an A + (inv)B function, so the two channels could be used to see differential signals nicely, but otherwise it has what I need and functions well.
