Hi everyone,
Last night I bought a USB oscilloscope on ebay it cost around $170US delivered and testing out the software - it is quite feature packed.
it is called the DSO-2090

You can actually download and use the software for it in windows.

Just open it up and it will say error connecting to the oscilloscope, just click ignore and you can use it anyway - it will also present you with a demo sig gen, where you can change the frequency coming in and then use the scope.
I used it last night and thought it would be much better than my small screen oscilloscope. plus, you can pause the signal, save data etc...
USB Oscilloscope with all the features - CHEAP!
