I got one (DHO802) and now plan to update to several. The added HDMI, 12-bit, USB-C power, and touch screen were the incentives. And all of them came true. Updated on-screen interface and better web-base interface were an added bonus. Shall replace 10x 1054z scopes in a teaching lab with these refreshed Rigols. PS: Had been futzing around with handheld, portable, and miniscopes. Probably have dozen in the last 5 years. However, with this DHO802 being so light, I can easily carry it around with a Shargeek battery.
Nice. Any regrets going with the DHO802 rather than the 814? I just ordered an 802 myself after much debate. But at US$299 vs US$499 and very marginal difference in specs, I just couldn't bring myself to order an 814. Have you tested the frequency response? Agilents we had in our teaching lab labeled 70 MHz were actually 100 MHz, and their 100 MHz ones were 150 MHz (for sinewaves). I realize I'm giving up some on the channels, but in 50+ years of scope use in industry, home, and academia, I never used more than 2 channels. Hope I made the right choice. But hard to go wrong with this scope at these price points either way !
No regrets, as I have never needed 4 channels for this lab class. None of my needs is over 20MHz, so am 5x below the 100MHz of the DHO814. Hence, no need for me to test. If I had 1GHz signal generators, then I would feel comfortable testing the 100MHz limit on the DHO802. Thanks for asking......JQuinn @@MegawattKS
I have DHO804 for a couple of weeks now, I really love the device. The touchscreen dramatically speeds up some of my actions. The portability is also amazing. Fan noise isn't that terrible for me but the collapsing legs seems a bit weak as they close easily. Also the grommet on the psu is very poor from the factory.
I'm deciding between the Siglent and the Rigol right now and I wish the GUI on the small screen did not waste so much real-estate on window dressing and fat borders. Do you think that's limitation? I frequently run 4 channels. Also, Is there a way to maximize the waveform screen to use the whole display? It seems silly to waste valuable vertical screen space on the Rigol logo when it's printed on the chassis. Siglent seems more efficient.
It's a nice scope that i wish was out before i bought the mso5074 with the logic probes. I done the firmware update as well. Its way more scope than i need and id have had money left over for a spectrum analyzer. Rigol rarely sponsor free scopes, sweet score man.
The help system on the DS1000z series was just about the best I have seen on any scope. What a shame they dropped it. And they definitely should have chosen rotary encoders with detents to make selection easier. I changed all of mine on my DS1100z
I bought a 1054z shortly after they came out. I bought one of these a few weeks ago, and have no regrets. Although the fan is noisy, it is not as noisy as the original 1054z fan. Couple of things, the wireless USB network dongle works fine, and if you are really lazy you can use a wireless (USB) mouse and keyboard.
I have an 814 as well and love it but why cant Rigol display nice numbers on screen calibration. viz at 21:00 vertical grid is 4.91 then 9.91, 14.91 etc. (5V/div). Calibration should be 5V 10V 15V etc. Displaying these numbers to many decimal places is crazy!! Also when changing timebase with a slowly repeating waveform with fast data results in a blank screen for a few seconds. eg Observing a 1ms pulse repeated every second will go blank for a few second when changing timebase from 1ms to 500us.
One thing that bothers me in all the reviews I've seen of this scope series, is the labels on the vertical scale. They always seem to be weird numbers with multiple decimal places. It's not helpful, it should be possible to quantize the vertical position and scale so that the vertical grid lines correspond to sensible numbers.
What sold me: 1. 12-bit 2. Low noise 3. 4 channels 4. Bandwidth (70MHz/100MHz) 5. Price (Cheap as chips!) While I think they could've made all of them 100MHz, I bought an 804 (70MHz) recently. Hopefully can upgrade soon to 100MHz, but then I probably won't need that as I work in audio. I'll make a video of my experiences with the 804 soon. I'm sure I'll be happy, as I've been using an analog 20MHz GOS-620FG for the past decade or two. About time I upgraded if I'm serious about creating electronics boards for audio engineers!
Compensation should be made on 10X probe mode only :) You switched from 10X to 1X accidentally right before you tried to compensate, it's even visible on the video at 14:59
The reason you did not get any joy from the probe compensation is that you had the probe set to 1X. Compensation is for 10X, not 1X. Sorry, looks like this was said many times before.
for the glossy screen i am pretty certain somebody on the forums had already found and cut to size / fitted a generic matte screen protector. to convert from glossy to matte wheras for the fan noise issue... well it requires some more significant mod to the rear of the unit. and depends which way you want to do it. for example 1 approach is to remove the entire rear plastic shell, and then drill into the aluminium heatsink some holes and threads for metal standoffs. to then mount behind a 120mm or 100mm or a 92mm computer fan. and then use (yet more) standoffs behind the fan to make it a 100mm vesa mount. while a different approach can be to just add some metal stanoffs + external fan. with the plastic shell remaining in place to hamper the airflow while a 3rd option could be to custom 3d print a brand new entire rear plastic chassis clam shell. with a home 3d printer. and whatever integrated fan or mounting options is best. its all a bit silly given the desire for a manufacturer warranty. in case something goes wrong, or you wish to resell the scope to somebody else. however the positive is that the 804 model of this scope is only $400~ which is very affordable price point to do custom hacks at. and then forget the warranty or resale value etc. since there are also several other desirable mods for the 804, primarily to add the port for the logic analyzer digital io. which is also well worth it for enabling mixed signal work and to have it trigger on packets or hanshakes etc.
I'm not a fan of adding matte screen protector on top of a glossy screen because it takes away from the already limited brightness. Somehow it feels like the old DS1054Z had higher brightness and there is no screen brightness setting exposed to the user in the new DHO800 series.
Got a Portable Touch Screen Monitor (on sale) and mounted both the scope and the monitor on a VESA mount, Now I got this on the big screen and can control it from the Monitor. This scope just has too much going for it to limit it to the tiny screen.
The features seem nice + the web interface for convenience but the fan noise for me is an issue as it generally bothers me a lot. Do you have any recommendations for oscilloscopes with very low to no fan noise?
As an owner of a DS1054Z from the early days, I have to say I'm a little disappointed by this upgrade. Agree that the fan noise (already an issue on the previous scope) and glossy screen are annoying. I'm sure someone will eventually come up with a replacement fan solution, but still annoying it's not down by Rigol themselves. I guess an aftermarket filter might help with the screen reflections, although might dull the scree brightness even more. The 12 bit ADC is nice, however. Software interface and touch control seems to be very nice, although it's going to be a struggle on a 7 inch screen; I really, really wish they would have gone for a bigger screen, as it's one of my main issues with the DS1054Z. I would love to see how this device gets on in "problem" areas for the DS1054Z: 1) The serial decode was always very hit-and-miss, 2) The FFT was always a bit rough, 3) The UI can become a hard-to-read cluttered mess once you switch on more than a small selection of measurement parameters (tweaking the font size helped a bit) and 3) the remote UI always felt laggy in actual use, especially with a mix of faster changing content. What is the performance of the GUI like once you start to load it up with four "busy" windows of content (say, one with FFT, the others with other complex math functions)? What are the restrictions in terms of shared ADCs, etc? I take it the headline specs are halved when using channels 1/2 or 2/3 together? Would really like to see how this scope holds up when pushed. Anyway, thanks for this first look at the scope. Would be great if you have the time to do a follow-up once you spend more time with it and push it harder. Cheers and all the best. :)
I think upgrading from 7inch screen to a 10inch screen is a good chunk more expensive so we'll probably get that in the next generation, 8 years ahead. Or you can simply opt now for one of the higher ranges that comes with a bigger display and a higher price tag.. Personally I'm not a fan of doing logic analyzer work on an oscilloscope because of the limited available screen real estate and functionality. I have a very good external logic analyzer that can do so much more than a scope would allow me to do. But I've never had any serious issues with the decoders on the ds1054Z, except for the obvious limitations with regards to the capture window, memory depth which sometimes prevented me from capturing all of the data I wanted to decode.
Same old serial and i2c decoders. As last resort only. Very bad compared to something like a dream source labs low end that can be had for 80 bucks US. Ps, I got the 802 and upgraded the bandwidth. Pps, the web mirror mode gives you a really good large screen. The hdmi may be better but the web mirror is super handy
But it would also take away from the brightness so I won't be installing one because of that reason.

@@voltlog connect regular PC keyboard over USB and press WIN+N. You'll get option to increase brightness ;) And also to add WiFi over dongle, enable ADB....
After watching this video, I'm pretty sure I'm gonna keep my DS1054Z for a while now. 😎 The only thing that I like about the new model is no Earth connection on test probes (Floating scope), everything else is 🤮
12 but ADC and high waveform capture rate isn't a bad thing. I can live without the glossy screen though. I already got an MSO5074, otherwise I'd be seriously looking at this. I really like the VESA mounts and how thin it is. I don't like the slow boot up, but I think that's to be expected these days since they're using a real OS (Linux/Android) which brings a lot to the table like nice upscaling when you use an external HD display.
Holy carp, if you are not wearing a black skivvy and black ski mask you can barely see what is going on. It explains why Jobs always wore a black skivvy with Apple's compulsory gloss monitors - lol -.
Not really, it will never show 200MHz in the menu, the probes are limited to 150MHz anyway. However the analog frontend is capable of 200Mhz and people on the eevblog forum have measured it to go that high.
