There seems to be a lot of variation in the price of the 4 chanel version of this scope: When sold for ~$300 - better save up for Siglent or Rigol. When sold for ~$200 - it holds its ground against similarly priced scopes. When sold for ~$100 - it is a fantastic deal. I got it when it was on sale for about ~$100. When it arrived, I was glad that there was an actual oscilloscope inside the box - at that price I was not sure what to expect. A quick look inside revealed the same guts as in Owon SDS1104. I was pleasently surprised how well this scope performed for its price. It gave me no troubles and it has met or exceeded the advertised specs. Limitations: - only two trigger modes: Edge and Video - memory depth is fixed at 20k samples (shared between all active channels) - no protocol decoding Good bits: - measured scope bandwidth is above 120MHz (in reference to -3dB point) - USB communication with PC. - accurate voltage and frequency measurement (in line with Siglent 8bit scopes) - has most of the common signal measurement options - FFT, slow and basic but still useful and goes out to 500Mhz thanks to 1GS/s sample rate. - fanless, for those who like quiet instruments. - runs of 5.5V supply and draws less than 2A so can be easily converted for battery operation. Conclusion: if you are looking for your first oscilloscope then don't dismiss this one as a mere toy - yes it has limitations but it can still be very useful for those who are learning electronics . It is in a league above all the $100 toy scopes, but still below the likes of modern Siglent and Rigol. In comparison to other scopes on Amazon in May of 2024 I would price this one at $160 - this is a fair price for the capabilities it offers. If you see it for less, then you are getting a good deal.
