| Sigrok & $10 Logic Analyzer from Ali Express |

| JenniferG:
I just watched the following video of a guy using a $10 Saele clone 8 channel Logic Analyzer (24mhz) along with Sigrok. The Sigrok software / Pulse View looks really nice. I can't wait to try it out when I get my used $100 Thinkpad T450 :) Should I grab something like this for $10 from Aliexpress? It's only 24mhz though. This video is 5 years old. But it's plenty fast for things like Arduino, since it only runs at 16 Mhz. Are there better ones for the same money now? I really like the idea of just $10. Or even $20. |

If I got something like this, woudl it replace the need for serial decoding features on a scope? I am looking to buy a 4 channel scope. Should I not be concerneda bout the logic features of a scope since I can get them with a logic analyzer? |

Which 4-channel 'scope doesn't have serial decoders? :popcorn: For $10 you could get one of these as well. They work in different ways and can complement each other... |

A scope isn't a proper machine to decode data. Perhabs for few bytes, seeing a single event, but not for large transfers. That cheap clone will be more useful for that, i.e. capturing 30 seconds and then later on analyze what's going on. 24MHz is plenty for a lot of things. You can also get a fx2 board which mostly the same, it'll work at 24MHz(8ch) or 12MHz (16ch). However it lacks a buffer, so it'll be 3.3V max. https://a.aliexpress.com/_EvEdTh7 |

But maybe I won't need 4 channel scope at all if I get this logic analyzer. I am into audio/synth electronics. All I have currently is Tektronix 2225 and it can't capture single shot stuff. So I need some sort of digital storage scope. 2 channels might even be sufficient. |
