While I have not used that particular brand, I would unless absolutely effing necessary not get a USB O-scope. I have a Velleman Unit that I have had for several years, and while it works, it is not a go to unit by any means and most of it has to do with the PC GUI side of it. It's not very smooth and because the unit I have was designed before windows 7, the Vista/Win7 driver seems to be flaky. From what many other people say about other USB 'scopes the consensus is the same. Get a stand alone that will allow you to connect to a PC for screen caps, and what not, but make it a stand alone.
Rigol make some decent stand alone DSO 'Scopes that are fairly inexpensive.

I was kinda figuring a response like that. any recommendations for what kinda specs to look for?Originally Posted by Six_Shooter
What are you using it for? What kinda of signals will you be reading? What environment will you be using it in?

it'd be used alongside the jimstim I just bought to verify functionality of code changes, so sitting on a desk reading mostly ignition and fuel outputs of an obd2 PCM.
You don't need a very high band width then, a 20 MHz unit will be plenty.
Like I said previously look at Rigol. I don't own one, but I have used the DS1052E, and it works well. There is a hack to turn it into a 100 MHz unit as well.
You could get away with an analog unit, that can be found on Kijiji/Craigslist/ebay for less than $100 in most cases.
The DSO does have the advantage of having built in measure and storage functionality, along with the ability to screen cap and control through a PC interface.
I find the standalone units much more convenient than the PC based scopes, no compatibility issues, no dropped coms, don't need extra hardware to run the 'Scope.
I haven't found any 'Scopes that have the same features and good reviews that the Rigol has, for the same kind of money.

alright, thanks! at this point, I'm looking for a good used unit, it's not a tool that will see a ton of use, so I'd rather not spend a fortune on one.
If you know anybody in college or a profeesor at a college, you can get this for $99. May have to do some padding with resistors on the inputs for the automotive voltages but has 16 channel logic analyzer built in. I am going to talk to one of my college professors who is still teaching electronics and see if he can get the student pricing. if he can, I may purchase one. Here is the sales sheet with some specs. http://www.digilentinc.com/data/prod...gDiscovery.pdf
I've read the Stingray DS1M12 is a decent unit. Haven't used one though.
