The halved sample rate when switching the trigger to another channel in single channel mode makes sense to me. It has then to sample the second channel. This would be the same like switching a additional channel on.
True, but it should know the channel is not enabled. Although I guess you could have a non-displayed trigger signal on another channel. Now that I think about it, yeah, that makes complete sense. So that's an official correction, it's not a quirk, it's a feature.
It shouldn't care: set a reference voltage and trigger a comparator when the input crosses it. Still a great value for the money but an obtuse design limitation.
Was about to order a DS1054Z when I stumbled on your review. Now a DHO804 arrives tomorrow. Great form factor and plenty of features for a hobbyist. Thanks for the detailed review.
I'm still blown away by the new scope. I mean, I was tempted by 10-bit scopes I'd seen in the meantime, but much higher price and less capability. Now this exists! Game changer. I'm sure the whole market is going to be totally rearranged very soon. No way it'll all stay the same. Competition is awesome!
Rigol owes you big ! I just bought one on the basis of your review and enthusiasm. For sure; Its a fine piece of equipment. Thanks for the excellent fun and honest review.
These scopes really need a second monitor output, not just a mirrored output. Then you could have your stats and math windows on the other monitor. That 7" display is just too small for it's capabilities. Dave, thanks for the excellent video. Even though I've got a 1054Z, I REALLY want one of these.
I'm not a android programmer, but i suppose that is quite possible to add, that's the advantage of use a base operating system, you can theoretically add whatever you want, but on the downside it MAY be a bit slow (i.e. boot time as we saw), prone to errors and power hungry.
hey man , nice that you dig it , i have a solution for you . Get another scope like it , and there you go , 2 screens , who would get that idea . I need 2 voltmeter screens sometimes , guess what i use 2 voltmeters .
Hey Dave, one thing you didn't go into much that would be interesting is the LXI / Ethernet functionality. And beyond the stuff specific to this scope, not sure if you've done a video specifically on LXI or not, but that's something I'd love to see. A (somewhat?) comprehensive look at all the things you can do with LXI, controlling the scope, or pulling data off the scope, over the network.
Well... guess what? I was one of those! Ofc the unlocking tutorial was a big push for it. And... relating to it. can someone tell me if updating the thing with a new software update removes those unlocked extras? Mine have some bugs on the USB related stuff. Managing files and save pictures its almost impossible.
That is seriously impressive. Even as someone who wouldn't have much use for a scope beyond simple power quality analysis, I'm incredibly tempted to get the DHO924S (the fully-loaded model).
Regarding the beige vs black colours... My wife and me are both engineers and have our "command centre" space (desks, computers, boards, etc., including small electronics workshop space) in our living room. That makes it a part of the decoration of the living room - since we are engineers, stuff like computers, screens, boards, soldering stations - are nice and fun decoration (assuming there is no mess), BUT my wife always has one condition: stuff needs to be BLACK to look nice with wooden desks. Screens - black. PC cases - black. Soldering station - black. Oh, you want to buy a scope and keep it in the living room? Great idea! But you know the drill - do they have black ones?
So if there is a must-have device for functionality but it only comes in a beige case, is that the time to pull out the sharpies and start coloring the case? ;-)
@@Sembazuru yeah... :) BUT, recently I accidentally learned that there is a waiver process for that :P and if I really really REALLY want (and have technical explanation for it like better parameters or outstanding bang per buck factor) I potentially can get us a beige equipment :P But I do not even want to know what will it cost me :P (apart from monies)
Dave, after you did your review, I bought this DS1054Z a few years ago. I still use with an upgrade to 100MHz and I am very satisfied. At that time it was number one in price. I won't be looking for a new oscilloscope for a long time. But it's good to know that Rigol is still releasing something interesting.
It's remarkable that both the hardware AND the software are high quality in this unit. This is some serious engineering at an astonishingly low price. Rigol shot out of the park here.
5:11 Why can you still buy the old ones? You answered that in one of your videos. IIRC: It's expected by customers to get spare parts and replacement of the exact model that is installed somewhere so that they don't get different measurements and don't need to change procedures. Also IIRC: only good companies would provide that long term support and that would be a reason for a higher price.
A few times times in my life I was considering 1054Z (as my first scope), and if there was a significant sale for them, I might have picked one up. But I'm glad I didn't, and instead, just ordered DHO804. Given my personal use needs, it will probably last me a lifetime (modified, of course). Thanks for the detailed review and teardown, they really helped me make the choice.
I had an old ring fluorescent light with magnifying glass. I got rid of the glass and added extended bolts where the springs were so I could add another set of springs from another junk one. It added quite a bit of weight capability to it. In any case I could totally mount that to one of those and you could just grab your scope out of the air and move it in your face and then back out of the way! I used it for moving around an old flouro tube 17" display and it supported it just great. I had to make my own aluminum Vesa converter mount but that didn't add much weight.
got a 1054Z 8 years ago, still going strong... but seriously considering the DHO804, the 12bit + vesa mount + HDMI out + mouse input pretty much sold me.
Do you know if anyone has done a comparison of those two yet? I'm trying to decide if I should buy one of the Rigol DHO800 series scopes or one of the Siglent SDS800X HD series.
@@ledricelektronika6635 it's been a great machine really. I had a little hiccup setting up the network connection initially but I worked that out. It's very easy to use and very easy to find the functions you want.
The main complaint I have about this new scope is the lack of 50 Ohm termination (which is really handy to be able to do in the scope itself, without having to muck with a physical adapter). But other than that, it's really incredible how capable it is. The fact that you can run it from a USB-C power bank is a killer feature as well. Rigol has changed the game with this one. What a time to be getting into electronics. You even get a quite usable FFT function. Crazy stuff.
I've used Picoscopes for quite a while since the USB interface and intuitive software makes waveform storage and documentation easy. The DHO800 has all the features I use at a lower cost which includes serial decoding. Hmm, worth looking at.
I still use my DS1052E. Granted, I don't use a scope at home a ton and at work they have some fancy Tektronics model, but for my personal projects the DS1052E still does perfectly fine. I got it based on your review and hacked it to unlock the full bandwidth. This scope looks like a compelling upgrade though, might finally be time to go 4 channel and have a more modern user interface.
@@mscirIIRC, Dave mentions it in his review of the scope. Also, IIRC, it won’t work if you have upgraded to the latest firmware. I haven’t updated the firmware on mine for this reason, but I think I’d rather get a new scope now, like this DHO800/900. I never got around doing the hack, as I haven’t had a need for a higher bandwidth. Like others, I have a problem with the rotary encoders on my DS1052E. Another reason to upgrade.
@@JohnSmith-fq3rg Fine with me, but please realize that you are buying hardware and software. The scope doesn’t do anything useful without the software. Software development costs money. Do you use the same reasoning when you buy software with different feature sets? “I’m not buying the software that locks me out of the pro features.” Or maybe you don’t buy it, because you don’t get any hardware at all?
12-bit is the game changer for sure -- how long have we been at 8-bit. I would not be surprised if, in another few years, we might see 16-bit. Here in the USA our TV standard was locked at SD resolution for many decades until, in the early 2000's, we went to HD resolution, but only a few years after that UHD was available.
This is all beautiful, and a dream come true: A good scope with great features at that price point. Only problem is that nobody uses oscilloscopes anymore. I was a design engineer at Tektronix, and when I visited our customers 30 years ago, every engineer had a scope on their desk. 10 years ago they were all gone. And Tek sales tanked to nothing. All the Tek buildings were taken over by Nike.
This sound weird, what is the reasond for this problem I thought oscilloscopes is a necessary tool for engineer? If they do not use oscilloscpe then what are they using instead?
Pulled the trigger and placed my order before finishing the video. This scope is more advanced than I’ll ever need so it shouldn’t become obsolete on me.
I should have NOT clicked on this video after buying my Rigol1054Z for 400 euros and hacking it to full functionality just 5 months ago. Gotta wait a couple more years to get a new scope, but I still love my hacked Rigol1054Z. 😄
Excelent review as always, you don't disappoint, but i think i'm gonna stick with the 1104, i don't like touchscreen, the cooling solution is VERY CHEAP, the USB-C is worse, i'll give that connector maybe a year? before starting to fail?, not to mention a slotted SD card with the OS (okay yes you can do a binary image and copy to another one) probably what i like the most is HDMI output with proper scaling, and the vesa mount, but the power connector and cooling solution.... nah, i'm sorry, also here in my country the 4 channel 100mhz version costs 1200 dollars, I can get the 1104 for maybe 800, not worth it for me.
The amount of bench real estate you dont lose is amazing. Thinking back to the 80s when i started my apprenticeship and we had those huuuge Tektronix crt scopes.
@@tactileslut It's noisy, but bearable. But I'd only buy the 1054Z used or at a decent discount, these new models seem like a good choice for the money.
The 900-series is pretty sweet for an all in one flyable scope/logic analyzer that fits in my carryon. It’s similar in size to a tablet in a rugged case. I’ll buy one!
I just got my DH0814 and the first thing I noticed was the warm burning smell (14:40). I am glad to see that it isn't unique to mine or representative of a problem. It smells like a hot resistor. I ran it through it's paces best I could to make certain everything seemed to be working so if needed I could send it back right away. Great review. Only part way through and already learned things I hadn't figured out on my own. Gonna design a back to fit the VESA so I can protect the USB cable and provide a place to wind the cable up and also snaps to store the power supply. Maybe a space to hold adapters, probes, etc.
I liked the video and gave it a thumbs up, but the big advantage to the other scopes you compared it with is display. That glossy screen is horribly reflective, unlike the wonderful matte screens of the older scopes. And while the Help system is for newbies, there are a lot of newbies. Even if you've had a scope a while, you sometimes what to know about a button function, and digging through a PDF is no fun. But other than that, I would agree with Dave's assessment at the end. It's all about the price and 12-bits. It's compelling me to pull the trigger and buy one despite the reflective screen and lackluster "help" system.
Will you also review the DHO914-S (or DHO924-S) later? I am interested to know how the signal generator relates to that of the DS1074Z-S Plus (or DS1104Z-S Plus).
Dave thank you for this. I was planning on saving my money for a newer used Tektronix scope, but came across your latest video found the datasheet and had to buy it. It’s amazing that this $400 scope seems to blow the DPO 2014B scope I use at work out of the water. Still love my Tektronix gear, but for the price and feature set it’s hard to buy anything close to comparable on the used Tektronix market.
Great review. The top of the line Phillips / Fluke ScopeMeter I bought in 1992 (they were about $1400 back then) finally completely and utterly gave up the ghost.. and I'm in the market for a new scope. I think this Rigol will do fine!
I've seen on other virtual scopes-- if you just hover over the time or voltage adjustment -- you can scroll the mouse wheel and it will roll it up or down. Much quicker to adjust it that way on your controls when doing the remote interface.
I've been following Kerry Wong as he's been reviewing a lot of low-end scopes, portables, etc. Don't really need one, but one would definately come in handy and under $200 really seems like to many compromises. $299 2ch is probably more than I'll ever need, and Rigol's seem to have more options available in that base model than I'll ever be able to figure out or need to use. I think it is a game changer for sure. Will be interesting to see if anyone has a 17"+ touchscreen that can be added to a screen.
On the forum the war is on between the Siglent turbo-fanboys and 12-bit enthusiasts, with no clear winner. An in-depth comparison between the DHO800, DHO900, SDS1000X-E, maybe the SDS2000X HD, would be great.
Wow, thank you for that amazingly comprehensive review plus taking the trouble to put links to all the different sections. You must have put some hours into that lot!
Surprised no one is saying anything about this running Android 7, which came out April 2017 (6.5 years ago). The lack of security updates when it's plugged into a network, would make it an easy device to hack.
@@gblarggUnfortunately, when the hacking is done over a network, it's unlikely to be being done by the user. Make sure that you have a good firewall on your LAN!
Just ordered a DHO814 along with an MSO5000. The form factor and ability to have the DHO814 on a VESA mount alongside my pc monitor and control it with a mouse, as well as HDMI out kills it for me, perfect for troubleshooting, whereas the MSO5000 can live on my bench where I do more experiments etc. My DS1074z, DS1052e and DSO1102G can be enjoyed by other people as they're all going on eBay. Rigol have really hit it out of the park with this. What an awesome piece of kit.
I am deciding between the DHO800/900 or the MSO5000 as my first oscilloscope as an EE student. Which one would you pick? I have an offer for 500$ for an MSO5000 used. Why do you need both?
@@LeonFisher-Skipper If you need the accuracy that 12-bit offers go for the new DHO800/900. The MSO5000 has many many more options than lower tier scopes and is hackable to 350Mhz. As a first scope I'd go for the DHO800 series as the MSO5000 could be overkill. I ordered both as I can see a use scenario for 12 bit, but I also need some of the features the 5000 series offers that are not available in cheaper scopes. I do more diagnostics to do with repairs by my computer and more playing around with circuits on my bench. I also really like the form factor the dho800 offers. Hope that helps.
I did the thing, I bought one and I'm like 5 minutes into the video. 😂 I've changed from a 100MHz HP 54600B with CRT screen and no analysis tools, just auto voltage and time measurement. I am so happy I've waited for so long. I almost bought the old one a year ago. I've survived long enough without all these nice things it's timely to upgrade from stone age oscilloscope.
That USB C port actually _does_ have a provision for securing the USB cable -- that little hole next to it is a threaded hole for one of the screws of the screw-locking USB-C connector variant to screw into.
I suggested a while back that they do something like the Panasonic Toughbook CF-19 with the USB ports. They have a USB fly jumper that screws into the case and when you wear out the USB port on the fly lead, you just replace the fly lead.
27:35 - it's quite logical: when you move the waveform - you change offsets in frontend amplifiers, but when you move fft graph - it just moves the picture of it, no changes in frontend needed
For $299 it wouldn't even be the most expansive Android tablet I own. This thing seems awesome. I really want it - altough I really don't need another scope. My DS1054 still has his options on trial. I hardly use it. I find myself using the small miniware DS212 more often, because it's more handy in my usecase.
It would be nice if they made a screenless version of the device, with seperate controls for all channels. I will hook up a bigger monitor anyway (due to my old eyes). And adding a simcard slot so I can make phonecalls with it would be handy too.
Thankyou for great tutorials, reviews and chat. I am going into retirement and hoping to get back into electronics. In the process I will pension off my BWD scope and either replace it with a Rigol dho814 or the Siglent equiv.
One factor is depreciation, Rigol vs Siglent when it comes time to upgrade and and resale if you do that type of thing the Siglent sell fast and hold their value the Rigol will have very little resale value and take a lot longer to sell. Will wait for rev 2 of this as with the other rigol stuff there will be bugs.
I can’t speak about Rigol in particular, but it is safe to assume any complex device has bugs in software and hardware. I remember an old figure (~1998) from a book on CMM (Capability Maturity Model) when NASA was the only (or one of a handful) Level 5 certified organizations. The overall cost of their development at that time was $20,000 PER LINE OF CODE. I can’t afford bug free software or hardware, but this seems like a bargain at this price point. A low resale price would activate be a benefit to me, as I’m willing to buy used, but never get around to selling my relics. Besides, how much depreciation can there be on a $400 scope?
Wow. Bang for the buck on these units is crazy. And the form factor is amazing! I can't believe this price for a 4-channel scope like this. Rigol makes good products.
Nice scope, maybe i have to buy one - but the USB-C socket is an expected source of disturbance for sure and something that puts me off a bit... a tiny USB daughter board would cost maybe one or two dollar extra and it would be easy serviceable...
A very excellent review and well done. About the best on You Tube. Really helpful in determining if I should upgrade or not. Thanks for this great video and taking the time.
14:56 "Its not hugely hot" But 57*C is still pretty warm. 57C would feel hot to touch. If it was on a small shelf with the back to the wall and other equipment next to/above it, the temp could reach 60+ C. What was the ambient room temp?
If one doesn't use the VESA mount, those threaded inserts might be a good way to mount a fan to the back to get some forced air cooling. Or if using the VESA mount, cobble together a custom mounting plate that has a fan.
Ha!!!☺ this guy is soooo absolutely caffeined-out that i almost bought a "Vegimatic" from him before i realized he wuz reviewing an oscilloscope!!! Great stuffs!!!👍👍
i wonder what siglent's answer will be to this, unless they roll their own silicon it will be hard to get a better version out without breaking the budget
I haven't heard anything, so no idea if they have anything in the works. They are unlikely to match the price point though as they don't have the custom ASIC's.
Outstanding scope, the only concern is the occasional freeze-ups caused by the Android OS. Rigol should seriously consider ditching Android for a high-quality embedded Real-Time OS like LynxOS or Nucleous .
Have them send you the 9xx so you can test the waveform gen and L.A. with their 400 cable. Honestly, if you bought the 914s or 924s you should get the cable for less. I'm developing SMPS so torn if the Bode/914S is worth the extra 300. If the cable was 150ish range, I would say yes as this is a great space saving device. but as it stands the L.A cost of 9xx series plus the 400usd cable make me just want to get the 814 and call it a day,
Part of the reason for the lower weight is the use of an external power supply. For my bench area it would be awkward to find a place for the external power brick. I do like that stats were shown in the left side bar and not in the corner of the waveform area as it is in the 1054Z. The built-in help of the 1054Z is useful to a point but it doesn't always give you as much detail about a feature as you might like. Having access to the full manual is useful but it would have been nice to also have a per button help.
Siglent 12 Bit scopes released this week with 10x more mem depth on all 4 active channels, and almost 2x more sampling rate for 4 active channels, please review them also
Wow, in 2019 I had to rent a 2GSa/s scope for laser experiments, it cost more to rent for 2 weeks than this entire scope. I'll pull the trigger when they reach a similar speed as I need it for nanosecond scale pulse reading.
Great video. I enjoyed all the detail. No comment about the glossy screen? There was lots of reflection of ambient imagery in the display. And every time you tilted or turned the DHO814 all I could see where lots of horrible finger smudges. And now that the Siglent SDS0814x HD is out at the same price point as the Rigol DHO814, it would be great to get a run down of the two to understand the trade off. On the surface, the new Siglent appears to be the winner.
5:10 Keeping the line in production is really great for departments (esp. Education) where there are big benefits to buying more of the same model you already have.
Dang. I'm just 9 minutes in and I already want this thing. :) Electronics is just a side hobby for me, so the Hantek DSO5202B (2 ch, 200 MHz) I got cheaply 10 years ago works fine for me. But I love the small form factor and much better / modern software (the old Hantek does not even have a intensity grading display, some of the advertised features do not work etc., and I don't think I ever needed the full 200 MHz BW anyway..)
Dave - i remember those 220 and their counterparts. TDS 3xFC where x is usually 0, F is the frequency in MHz and C was the channels. TDS 3054 and the B variant - wrote automation test and adjustment procedures for them.
It would be great to see a shoot-out between this and the newer Siglent SDS814x HD. I have the Rigol DS1054Z upgraded to 100MHz. It's a great scope, but I'm annoyed by the protocol decoding, which requires that the trigger signal be visible on-screen or it won't decode. It's quite limiting and most of the time I find myself just decoding by hand. Has the DHO814 improved in this regard?
Oct. 6, 2023. I just checked Amazon in the US and the price for a RIGOL DHO802 is $ 299.99. it will be available October 8, 2023. I already pre-ordered one for myself.
Subscribed at video #1 and also, because of the video, bought my first ever scope... the DS1052E... still use it today and love it... just a bit challenged in the channel department.
I wish you would have done a memory depth demo... For example: zoom out and record 10 or 15 seconds of can bus and then zoom down into the waveform and see how clean it looks. Do a few experiments and calculate how long it takes to reach the memory limitation, etc.
@@alejandroperez5368 That's fine.. I just want to see how well the memory is actually constructed and when does it apply limitations. I bet it's trash if you're using all 4 channels. :(
This thing is one of the most interesting objects I've seen in quite a while. Unlike several other affordable scopes I didn't really see any downsides of consequence here. Definitely tempted. Unfortunately they're quite a bit more expensive through the single source import company in my country.
When the "app has stopped" message appears, you can see at 46:36, that the app reappears in the background, so it looks like the system restarted it automatically, but kept the crash warning on the screen for your information. This is pretty good. What I hated in the DS1000Z was that the up/down arrows were placed differently on the left and right edge of the screen. Not only for aesthetic reasons; it was really annoying to have to constantly pay attention which side of the screen I was pressing the button on.
