So... if supposedly knowledgeable people buy a cheap-as-chips oscilloscope that's so new that there's still a waiting list to get one, from a manufacturer that isn't famous for speedy/regular firmware updates...
...forgive me for finding it amusing when thay act all indignant about having a few bugs then post several times about how they're sending theirs back because they have some important work that needs doing.
If you have work to do and need a specific function then buy something you know will do it. Anything else reflects more on you than on Rigol.
I assume you are pointing fingers at me here, Fungus, and you may be partially right. I purposely ordered the scope at a distributor who offers the no-questions-asked return policy for this situation.
But we may argue about your terminus "few bugs". I'ld rather consider the findings major shortcomings than just bugs. Please keep in mind that I would have spent round about 1000€ on the DHO914S including the digital porobe set.
I considered buying only the scope and making the probe set myself as per the instructions found here and elsewhere but finally decided against that since Rigol's digital probe set comes with proper connector housings, fast adjustable threshold comparators, a wide input voltage range (so I can even use it on ancient p-mos circuitry -- sometimes I'm a sucker for ancient calculators, right now I've got a broken Compucorp 326 calculator with a faulty ROM chip on my hobby table) and comes with resistive interconnects and 32 quality microclips which adds up to combined representing some value for the money, considering the time required for a DIY solution and the limited performance (but that's OT).
I several times told that I still consider the DHO800 a good choice, especially after Rigol will eventually have addressed the problems found so far. Btw, IMO the sampling / aliasing findings are not a real issue (for the DSO only modes -- the additional cut by half when the digital channels are enabled is a no-go). Maybe they would be for someone new to DSOs, but once familiar with with the matter, you just have to observe the sampling frequency and know what kind of signals you can measure accurately and what not, and if unsure, start with a single channel and enable additional channels as possible/required. It's just a question of common sense and some discipline.
But if I intend buy a new product for a sum that's not too far from other, proven working products, I at least expect it to provide the promised features in a way that they are useable / useful. I gave Rigol a chance despite knowing of their history of slow problem solving, assuming / hoping they have learned from the past, only to find that basically all the added functionality that I intended to buy the DHO900 for, are unfinished construction sites or hardware-limited to a degree that wasn't forseeable from analyzing the teardowns and early reports of the product. So I decided to pull the safety-line, that's it.
I've got enough equipment that covers the basic oscilloscope functions, but if I've got (or just want) to replace one of these in future, the DHO800 is probably still high on the list, provided its performance matches the requirements.
If this approach amuses you, well, I'm glad you found some "joy" in my contributions
All the best,
Thomas
