A few words about Hantek MSO5202D. Despite what everybody says about Hantek, this model is actually quite nice, if all you want is something better than a Tektronix TDS210: same great interface, very same button location but higher bandwidth, nicer screen (color!) and digital inputs. I have one, which I bought new a few years ago for about $170. As a general bench oscilloscope it is better than any handheld Owon HDS you might get for the same price (in terms of interface/usage; not so if you want portability, of course). Be aware though that it does not have any LA capabilities (at least mine doesn’t). Sure, you can display digital signals synchronized with the analog output of a DAC (for example), but if you want any decoding you have to do it en papel, with your favorite pencil. Just saying. |

This display feature has become standard in entry-level oscilloscopes starting nearly 10 years ago, and I would not buy any digital scope, used or new, that does not have it. Intensity grading shows frequently drawn traces in brighter hues than infrequent ones, similar to a cathode ray oscilloscope, while still showing the infrequent traces more clearly than a CRO. With the simple on/off pixels supported in the first generation of DSOs, you lose this important information. This makes it very difficult to recognize outliers vs. typical signals, and may flood the display with bright pixels hiding relevant information "underneath". The Rigol DS1000Z and Siglent SDS1000X-E series, which were mentioned a few times in this thread, both support intensity grading, as do other recent scopes in their price range. The new DHO800 series of course has it too. |

This really shows up when you have really infrequent variations on a signal or very complex variations mixed in. |
