BMW owners justify spending more on their cars by going on and on about how fast they are and how they handle in the corners, how every other brand is somehow "compromised", etc. It all makes sense on paper but the simple fact is that most people just want to get around the place at normal speeds and carry shopping twice a week. A Ford Fiesta can do that perfectly and isn't missing any basic features like aircon or wheels. Don't believe me? Siglent owners give the exact same excuses for not owning an R&S as BMW 3-series owners give for not owning a 5-series or 7-series. Maybe when somebody asks "what 'scope should I buy?" we should start out by asking them what car they drive and answer accordingly. I predict these threads will be a lot shorter if we do that. --- Quote from: Veteran68 on August 15, 2023, 11:21:16 pm ---Thanks to sub-$500 oscilloscopes, now any semi-serious hobbyist or maker can afford a scope. Since those people are likely a majority of this forum, I'd say $3000 for a scope (while certainly cheap for commercial use) is still WAY out of reach of most of them. I certainly won't pay that for my personal use. --- End quote --- Yep. --- End quote --- Another bad car comparison..... What are you tryin to say? I honestly don't get it? |

If so, why not show us the results, so everyone can see this "perfect capability" with their own eyes? I do not doubt that it can do it, but seeing is believing... --- End quote --- Dave's video was about pretty much nothing other than noise measurement: |

As I said before, it seems Rigol uses decent ADC this time. And it seems to be (very?) decent noise levels, hardware vise. But that is hardware "promise". With half baked FFT and unfinished software not there yet. Problem in the real world is that measuring microvolt levels is not easy, and it is questionable if OP can make setup that will be better than the scope he has now... As Nico says, probing, grounding, shielding etc is critical here. It is unclear (even to OP) what he really needs. Saying "600 uV levels on power supply" without stating is it RMS or P-P or what BW is not really clear requirement. Also depending as to what this power rail is for maybe such low noise/ripple levels are not needed at all, i.e. devices powered also have it's own PSRR that might be sufficient for power not to be critical at all... |

I honestly don't get it? --- End quote --- Maybe not os bad. We Drive a pair of Siglent's and our MSOs (Max Speed Object) are a pair of Porsche 911s, one is a Twin Turbo (Black) for the faster waveform captures ;) Rigol has apparently developed a good custom new engine (12 Bit ADC) and new chassis (OS) but hasn't quite got the handling (UI) refined yet, whereas Siglent is using a GP engine, older chassis (OS) and has considerable refined handling. So on the Track (actual use) the Rigol is fast on the straights (simple tasks), but struggles in the braking & corners (skilled tasks) due to the handling (UI) and suffers slower overall track times (user experience), whereas the Siglent is fast everywhere with the superior handling (UI) and sports an overall quicker lap time (user experience).

Clue: Nobody's saying you're wrong. |
