I guess it would require some frontend to get the voltages in the right scale and perhaps fancy overvoltage protection. Obviously you can do a lot better than 3.5ghz these days, but for audio and simple electronics it seems to be plenty.
- KGIII 9y agoJust use your laptop's mic jack to make an oscilloscope. http://www.instructables.com/id/Use-Your-Laptop-as-Oscilloscope/ http://www.instructables.com/id/Use-Your-Laptop-as-Oscillosc...
- tinco 9y agoWell I'd hope for a slightly better range than 20Khz and maybe resolution. Also I'd imagine the noise level wouldn't be very satisfactory. With a 3.5ghz oscilloscope you could work on Mhz order chips, power supplies and who knows what other fun stuff.
- KGIII 9y agoI figured you were just looking for something to toy with. I figure that turning this device into a scope is not going to result in an accurate scope nor something that would be useful beyond entertainment value. It seemed like a good idea to recommend something cheaper, easier, and better documented. Besides, who doesn't want to use their mic jack as an oscilloscope? ;-)
- dahtguy 9y agoYeah, it would require quite a bit. Note that while it can input a massive frequency band (10M to 3.5G), the sampling rate is quite small (~31MS/s). Would work much better as a spectrum analyzer than a time domain viewer. You can definitely use it as an oscilloscope, but it's non-trivial and has many limitations. Recommend getting a cheapo analog one, or if you're already at the normal SDR price range, just going for a Rigol
