New small scope, this time hopefully with real specs: - Sampling rate 40MS/s - Bandwidth 1MHz/18MHz - Sensistivity 20mV/Div ~ 10V/Div - Time Base 50ns ~ 10s - Generator Frequency: 0-500K, 3.0V - Screen 2.4 inch / Resolution 320*240 - Size 87*58*18mm http://www.sigpeak.com/productinfo/dso154pro.html http://www.sigpeak.com/download/ZEEWEII-dso154pro_UserGuide_En.pdf https://youtu.be/BmaMLNnN-rc |

Some instruments specify 5mV max ripple, how can you see that with such poor sensitivity. |

I don't know why we need so many of those cheap scopes. They are useless. The only thing I can see something like this being useful if you are making one your self from scratch as a somewhat advanced hardware/firmware project. |

I think something like this is probably adequate for kids tinkering with electronics. I'm spoiled now but I would have been thrilled to have something like that when I was a kid. Limited, yes, but not useless. Sort of a VW Beetle or Lada, they weren't great cars by any measure but they were affordable and better than walking. |

I agree. They have their place but probably more akin to a Wal-Mart bicycle. :-DD Using the older DSO-138 and a $15 FG I was able show my nephew how to plot the FR of simple RC audio frequency low-pass, high-pass, band-pass and band-stop filters. A $100K Keysight would probably give more precise results but I doubt he would learn anything more. |
