I'm talking about a first somewhat "complete" scope that opens a door to a new world. --- End quote --- I'll sell you a very "complete" working recapped Tek 2465 4-channel 300MHz scope for £300. I have two, and ought to reclaim the space. --- End quote --- That is 380 USD and I don't think that is good value for someones first scope. For approximately the same you can get the new Rigol or Siglent, which after hacking will be 200-250 MHz. The old CRO has slightly more bandwidth but that is also all it has going for it. The new scopes have warranty and a list of features too long to repeat here. |

Either way you'll likely sell it in a few years. |

But the decodes only work with what is displayed on the screen, i.e. a few characters at best. --- End quote --- Not true of the DHO800. --- Quote from: tggzzz on February 22, 2024, 12:15:25 pm ---Better to use a separate tool dedicated to that, e.g. a cheap protocol analyser. --- End quote --- Do you know of one that does constant real time triggering/decoding/updating? Last month I was coding a bit-bang I2C function; I think it would have been a real pain in the ass to constantly hit record on the LA, upload the program, wait a few seconds, press stop, then go mousing around looking for the data packet to see if it was OK or not. My oscilloscope just sat there constantly decoding, all I had to do was upload the program and turn to look at the result on screen at each iteration. |

I'm thinking of selling my Micsig STO1104C if you're interested. Shipping from Spain. |

Another inexpensive option is a low end picoscope. I have a 2205A in an edu version (translucent red case, Allied Electronics had their name on it), and it does pretty well for most simple needs (which applies in my case). There are downsides of course to a pc based scope with a limited bandwidth, but for the price you get new hardware and software that is the same for all their scopes. The newer version of their software is more modern, and is designed to be touchscreen friendly, but I would say you will need to use Windows (or maybe OSX) as that is their primary focus (they claim to be able to run on Linux, but every time I attempt that there is some problem). The ui is well done on version 7, and you can download and play around with it if you want to get a feel for it. I do like having a screen size (laptop/desktop) that doesn't require a magnifying glass, and using a mouse/keyboard puts you in familiar territory for dealing with the user interface. I think the lower end picoscope makes for a nice entry into scopes, but as you start to climb to the higher models you start to match prices with the stand-alone scope and now price goes out of favor (but price does not always rule). If you do get a lower end model and later decide to upgrade to something else, you will know why you are upgrading, will know what you really need (and are now lacking), and the inexpensive pico will still be useful as a secondary scope. They do have a number of videos and app notes available, but if they had some beginner 'course' that would take the user from A-Z I think they would sell lots of these things for edu (also make some translucent colored boxes like Allied did). Maybe there is some course ware for these that I'm not aware of. Just a thought. |
