As I know, although unlock the 1054z, 1054z does not working as a 100Mhz. 1054z really working as a 100Mhz after unlock ? |

I just got a Owon VDS1022I from the last Black Friday sales from Aliexpress and it is quite the scope for a beginner. The non-isolated version (VDS1022) is cheaper and probably enough for your beginner stages. The drawback, obviously, is the need to have a PC around. But the software is quite easy to use and very capable. |

My first oscilloscope was a similar PM3055. I paid the same price that PM3070 went for, but this is Brazil and such things are expensive here. Go for an analog oscilloscope if you can find one for cheap. There aren't a whole lot of reasons for a beginner not to go for a digital one IMHO. That's not to say that analog scopes aren't useful - I still use mine - but entry-level digital scopes have reached a price point in most of the world where it doesn't make sense not to get one of them instead. A DS1054Z seems like a decent buy. |

--- Quote from: Dan9550 on December 02, 2019, 07:11:57 am ---thanks for the tips guys. i'm probably only going to be measuring things like vintage electronics, arduinos, noise on power supplys at this stage. just whatever i'm curious about so i figure it will be eaasier to find a cheap analog scope for that. the scopes alkmar suggested feel like more of a stage two for me at this stage. --- End quote --- Arduinos. That means digital with its ability to use single mode triggering. --- Quote ---in terms of the number of channels i suspect being a beginner two channels would be fine for me. but obviously being able to analyse multiple channels at once has its advantages, what would the usuall use cases for say 4 channels be, probing multiple data buses or something like that? --- End quote --- Four channels instead of two makes it more convenient for decoding protocols such as SPI for example. Modern digital scopes, even the budget ones like the Rigol and Siglent models, decode digital buses such as SPI, I2C. |

Don't forget that, for protocol decoding, an ebay 8 bit Saleae clone USB logic analyser, used with Sigrok Pulseview, is far more capable at decoding than the usual 4 Channel scopes. For a ~$10 outlay, you can have twice as many decode channels, and reduce the number of channels needed on a beginner's scope (to two). Note that a LA isn't a substitute for a scope, it just takes care of your protocol decoding needs. +1 on the Owon (stretch to the 'I') for price-performance and UI. |
