Clock rates for CPU and RAM are way too fast, as are the modern serial buses (PCI, USB, SATA...). You can still use an entry-level scope to check out the power supply, as well as slower serial buses in a TV (I²C, maybe SPI if used). And of course you can use the scope as a learning tool. For frustration-free learning, the Rigol is probably the better choice than OWON or Hantek -- if only because it is more popular, so it is easier to find advice online. Actually, I would strongly encourage you to spend even a bit more and get a 4-channel scope; they give you much more flexibility. Maybe you can find a good deal on a used Rigol DS1xx4Z or Siglent SDS1xx4X-E. I would expect that quite a few hobbyists are getting ready to replace theirs by the new generation of 12-bit entry level scopes, Rigol's DHO800 or Siglent's SDS800X HD, and may try to sell their old 8-bit scopes. Those 8-bit 4-channel scopes are also still available new, but I would not recommend them since they seem too expensive vs. their new 12-bit siblings. When looking for used models, they should sell for significantly less than the current new price. If you can afford one of the 12-bit models, that' an even better choice of course. But these (only available new today since they were only released recently) may be outside of the price range you are comfortable with. All mentioned 4-channel scopes, 8 and 12 bit from Rigol and Siglent, are easily hackable to higher bandwidth by the way. |

Apart from that, it's always a question of price. Would I buy a Hantek for $300 or more? No way, but for $130 it offers a lot. --- Quote from: jackobo on April 01, 2024, 01:18:13 pm ---But If theres more pluses towards Rigol, of course I'd make an effort to save extra 90 quid for the thing I'd be using time by time ))) --- End quote --- As I said, the Rigol is clearly more recommendable if you don't mind the price. |

I bought Hanmatek branded versions via AliExpress. Both are quite satisfactory. The FFT update rate is fast. $135 + tax delivered for a competent 2 channel 140 MHz DSO? Looks good to me. It's Tek 465 with waveform storage. I'd recommend either as a budget bench scope. Bang for buck for ham radio the Owon HDS272S is the best. But has small screen. Can the Hanmatek scopes be hacked with OSHW? That would get really interesting. |

I could get the Owon SDS1102 for 199€. I want to learn and look into stuff, mostly analog guitar pedals and some arduino stuff. Is this wasted money and I should go e.g. with a Rigol DHO80* or am I just fine? I want to avoid buying multipe devices and I want to avoid buying the cheapest on Aliexpress. 400€ for a DHO802 is a lot of money even if I know that these are entry level scopes... |

The Hanmatek label version is commonly $135 US from Hanmatek's AliExpress store. They can't do any bus decoding, so not useful for serious MCU stuff. Tek 465 with trace storage and FFT is the best description. Have Fun! Reg |
