    • "Full featured scope" by zerucha on 8/6/2010
      40MHz Dual Channel Digital Storage Oscilloscope
      Overall: 5 out of 5
      Value:
      Quality:

      When I ordered this scope I was worried since the similar known brand scopes were a lot more expensive so there might be something not included. Instead I was greatly surprised that everything worked as well or better than advertised. It even has a connection to a Windows PC (though the software is buggy in place or I'm doing something wrong). I'm still looking for something they left out, but everything is there a fully tricked out midrange scope would have. It is a little larger and heavier, and there is no battery option and it has a more plain look. I look at automotive protocols and and they have different waveforms. I can get multiple comm packets, and the 10x zoom is still useful - it captures enough samples. It has all the modes, measuring - even FFT! and the interface is familiar. All the extra triggering modes I need like pulse width. I keep looking for missing features and instead find more than I expected. As easy to use as any other scope (which is to say no better, but it seems to be a standard to have side menu buttons). The only thing better would be more samples so I could do really deep zooms, but even having 2.5k makes this an excellent value.
