Great resolution too. I can't believe the 924S I got is so feature packed with no issues. It does everything my R&S does, most of them just as good. I even like the way Rigol does the cursers more than the R&S.
Things I don't like, not much just a couple of nit picks. It could load faster, it takes ~45 seconds to come on and because of the small screen some times I have to touch it a couple of times to register my selection. (Hint, get cheap stylus, made working with the scope easier).
China is moving up fast with higher quality products like this, it's a solid well built scope. A real game changer for $800 and 12 bits resolution to boot and it's tons of fun to play with.
Highly recommended!
- Really low sample rate (1.25 GS/s for 1 channel but only quarter of that, 312.5 MS/s, for 4 channels) puts a limit on the frequency of non-sinusoidal signals DHO924 may show without significant false ringing. I want at least 10-20 samples per period of a signal that has a lot of harmonics (e.g. square wave).
- Absence of dedicated per-channel controls. I understand the desire to use the same board and case for both 2-channel and 4-channel scope, but some of us would gladly pay $100 more for per-channel controls. Alas, it looks like per-channel controls will be extinct soon (darn global warming! :-).
- The scope is really tiny and very light. I prefer more substantial ones that do not try to shift and/or fall when I press buttons.
- Minor: no enclosed user manual or quick start guide. PDF file is easy to find online. Saving $1, Rigol?
- Minor: theoretically, 250 MHz scope but sometimes manual says the limit is 200 MHz. So is it 200 or 250? I say "minor con" because -3db point (practical bandwidth limit of the front end) slightly exceeds 300 MHz (nice!). The real limiting factor is, IMHO, not so great sampling rate.
- Minor: 10.1" display would be much nicer than 7" one installed in the scope. Nowadays, the cost difference is so small... But I understand the desire to save few bucks and/or push overly picky customers towards more expensive products like DHO1000x series.
- Minor: audible fan noise. Not terrible but, nevertheless, annoying. If the product were larger that could be easily addressed.
Minor: takes forever to boot. The cost of using Android?
Pros:
- 4 channels cover 99.99% of needs whilst slightly cheaper 2 channel scopes are good enough in 90% of cases. IMHO the slight premium one has to pay to double the scope capacity is well justified.
- Once booted, feels fast and very responsive.
- Easy to connect via Ethernet or USB and access, control, program from a PC or a laptop.
- Really nice low noise 12-bit front end (vs traditional 8 bit FE).
- Built-in and free decoders for the most popular protocols (UART, IIC, SPI, CAN, LIN).
- Priced on par with other entry level 200-250 MHz 4 channel scopes. High end brands like Agilent, Tektronix, Rohde & Schwartz, LeCroy, Keysight want more. Much more.
- Support for optional $400 16-channel active logic analyzer, PLA2216. I put into pro section because a) the analyzer is really well built, b) the user gets an option to have a true mixed signal oscilloscope (though I will dare to say that those who really need an MSO likely will need faster scope. For students?), and c) most popular protocols -- one at a time -- could be decoded via built-in decoders, without this option.
- HDMI output allows the use of better monitor, screen, display.
- USB C power allows the use of power banks. Reportedly, 90 Ah will easily run the scope for an hour.
- 100x100 mm VESA mount on the back allows flexible wall or bench or shelf attachment.
- A lot of memory. Default 50 Mpoints, optional ($150) 100 Mpoints.
- Built-in 25 MHz arbitrary frequency generator. The same scope without AFG costs $100 less.
- Junior models are slightly cheaper and, with some effort, may be hacked.
- Much, much, much nicer than previous star, 8 year old DS1054Z (hacked to the max). At least that is what people say who tried both (I do not have 1054Z -- it is too slow for my needs).
Conclusion: it seems to me that pros outweigh the cons. Recommended.
4 channel, 250 mHz, 12 bit vertical resolution - what more could you ask for.
See David Jones for full review.
But this commentary is about the documentation. I've purchased a lot of Chinese made products. Maybe over 1000. Documentation is almost never of any value. But the Rigol documentation couldn't be better. All documentation is by download.
It includes:
* a 30 page Quick Start guide
* 270+ page User's Guide
* 426 Programming Guide
The documentation written for this scope couldn't be better. And I couldn't be more happy about it. And it's even in readable English. Not like some that are run through translation software, where you need a translator, to understand the translation.
The owner's guide covers every button and function of this scope. The programming guide, includes the syntax and use of every command. It even has programming examples at the end.
Thumbs up for Rigol's attention to detail.

数世代前のSGやデジタルストレージオシロも所有していますが今回12bit解像度でLAN経由でリモート計測可能なことから踏ん張って購入しました。
おかげでこの様に簡単にボード線図が作成でき特性が把握できました。
まだまだ、バグと思われる不具合が多々ありますがバージョンアップを既知してメーカーに申し入れたいと思います。
添付されていた電源のACアダプターはPSEマーク付きの日本でも使用できる電源でした。
接続して5Vからネゴシエーション後は説明書の12V4Aではなく、15.1V 2.42Aの36.65W消費していました。
これからこれ等の特長を生かして電子工作に使っていこうと思っています。
