200 kHz obviously goes higher than the typical audio frequencies, but it's still a pretty limited bandwidth. I'd still look for one that has a bit higher bandwidth, preferably 10 MHz or more, just because it'd be more versatile. You could probably pick up a Tek TM502 and an SC503 10 MHz storage scope plugin relatively cheap. Or go with that 100 MHz scope that was posted earlier. > > I am not sure that a scope is particularly useful for spotting noise > spikes anyway, unless you plan on scrolling through huge amounts of > data. Depends on the type of noise. If it's constant, it'll probably show up on every sweep. If it's one of those "happens once in a blue moon" kind of spikes, then a DSO or other kind of storage scope is the only way you are going to find it. > > -- > atp Mark ------------------------------------------------------------------------------ Master Java SE, Java EE, Eclipse, Spring, Hibernate, JavaScript, jQuery and much more.
