content: Define how you are going to use it and derive the required specifications - and what isn't necessary. Categorise them as "must", "want", "would be nice if".Define your constraints.Read all the other threads on the topic in this forum.After that you may get some relevant and valid opinions.

content: Quote from: GeorgeOfTheJungle on May 12, 2017, 04:11:47 pmIn that price range there is way more out there. I wouldn't spend several $k on a Rigol or Siglent due to too many bugs, practically useless (checkbox) features and very few updates.tggzz has good advice: first define what the oscilloscope is to be used for and then decide. Maybe it turns out it is better for the OP to buy a used oscilloscope. You never know.@JanJanssen: The lower end Keysight and Tektronix equipment is also made in China.
