#ElectronicsCreators #Rigol #Review - Наука та технологія
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.
@@EEVblog I suppose it's probably doing those functions in software on the output from the ADC. Maybe even on the captured data in the RAM.
@@BrianG61UK Yes, it doesn't have the extra hardware to bypass the ADC.
it's not possible to trigger on a channel that's not enabled, because the triggering is *DIGITAL*
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.
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.
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 was unfortunately opposite. I ordered ds1054z than found this video. I ended up reselling on eBay for what I paid for it tho and got a DHO804.
ME TOO !!
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.
Incredible value for 12-bit scope! Groundbreaking at $299!!! Thanks for another great review!
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).
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.
That would be cool.
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.
Hdmi port is crashing
Always love Dave review on oscilloscope, very detailed analysis 😊
I bought a DHO804 yesterday. I'm really looking forward to trying it out.
Thanks Dave! I was thinking of buying the siglent oscilloscope but I am convinced that the new rigol oscilliscope is much better!
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!
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.
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.
I've ordered one, I love the form factor and the features you get for the price are fantastic.
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.
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.
The size of this thing is perfect, as are the specs, absolutely perfect for the money..Thanks for sharing buddy.
Never been more excited watching his reviews. An Aussie Treasure.
Thanks again for another great review that is a wonderful little entry level scope hard to believe what we can get for that price these days
Great video very well done Thanks for sharing and taking the time. Really helpful
Dave, I wonder how many RIGOL DS1054Z scope purchases you are responsible for with that iconic review video. I'll start the count off with 1 (me 😀)
With hundreds of thousand of views, I would have to be directly responsible for 10's of thousands of sales. Didn't make a cent from it, I'm dumb.
@@EEVblogask them for an affiliate link next time 😊
@@EEVblogI bought my agilent mso 3000 series and two rigols after your videos
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.
@@EEVblog Need an EEVblog branded model.
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.
Now if they would only give us affordable spectrum analyzers and RF generators.
there already are. Check Siglent. They are already very cheap, compared t owhat it was not that long ago.
The Siglent SSA3021X Plus is a bargain.
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.
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.
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.
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!
This scope is so nice, really happy with the new bar set for this price point
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).
That serial decoder built in is incredibly useful!
Absolutely astounding! hat's off. I want one so badly now lol!
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'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.
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.
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.
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.
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!!!👍👍
Beautiful Muriel!
thanks for the review, just got the 804 and grate for ebike repair and Arduino projects.
Time for a new comparison: Rigol DHO800/1000 vs Siglent SDS800/1000X HD
Great review as always.
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.
Wow... Mark me as impressed! I think one of the 900 series is going to be making a home in my workshop very soon.
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.
Great review
The ultra acquire mode is awesome, quit helpfull to debugging, loving that
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.
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.
Dave, i'll find find the memory/samplerate behavior also on older Tek's DPO7254. If I have measurements on other channels running with channels deactivated on display. I suggest the triggering is done in software and thus the scope needs to fire up the desired but not displayed trigger channel.
i already have a scope that is good enough for what i'm doing but i'm really thinking about buying this one , always good to have a backup scope.
if i needed a new one, i'd probably pick up the 4 channel.
my 1054 is still kickin though, and does the business for what i need.
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.
I still use my 1052E, but it’s a teenager now and rebellious. Perhaps it’s time to upgrade.
I was considering the Rigol 1054Z, the person offering said it was a deal for $400.. Watching this made me happy I didn't pull the trigger on it lol
nowadays people sell the old shit for more.
I only buy new.
Great video review! This convinced me to get four of these for my electronics classroom.
What make/model touchscreen monitor is that you're using at 9:44? It looks like exactly what I need for another project. Thanks, Dave!
Excellent review! However, price in the UK starts at £370 which is USD $450 - considerably more than "$299". WTF !! 👿
4 channel, or 2?
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.
I was about to buy a siglent sds21xx, but this looks nice for the price cut, screen split options for decoders!
Impressive for the price! I wish there was a similar spec:ed scope but with higher samplerate. Recently got a Siglent SDS2354X Plus but I was disappointed in how it handles fast and narrow pulses - sub nanosecond. This is due to having only 2Gsa samplerate. The Tek DPO I had before had 2.5GSa and did much better despite having lower analog bandwidth. The Siglent properly resolves the fast edge, but if the pulse is narrow, the triggering struggles, making a jittery and jumpy display. The "one scope for all purposes" thing is difficult... :)
Great review Dave, where can i buy one of these? I don't see 'em on amazon yet. You should edit the description to drop an affiliate link in the description, heaven knows how many 1054Zs and EX330s have sold because of your recommendation to hobbyists.
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.
Totally blow me away! I have a vintage Tek TDS1012 100MHz/1Gs 8it, time to upgrade.
I wouldn't .
your tek is made in Japan .
that sais it all.
this one is just very expensive China junk .
I have 2 tek oscilloscopes and 1 AWG.
they just run and run and run and I trust their measurements.
Chinese - no.
haven't seen any decent office use them.
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.
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.
Sheesh, I kept thinking I'm totally OK with my 1054z until you started all of the touch-screen stuff followed by FFT performance. Thanks Dave! 🤑
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.
Fantastic product. Too bad it's missing an external trigger channel. I have had several Rigol scopes... all have been very good.
Oh, that's indeed a big omission.
Hi love the channel! I have a question. It maybe a dumb question but how come we don't have cheaper high bitrate adc is it harder to produce than a DAC or is it the frequency bandwidth that becomes a issue for high resolution ADC
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.
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.
I was going to buy a Siglent for Christmas this year. Looks like I will be picking this guy up instead. Should go well with my Fluke 289.
Lovely piece of gear.
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)
Staying with 1054Z, though that FFT in DHO800 is incredible … 😮
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...
Dave, at 25min in when you are showing the capture update rate, and adding more channels, the sampling is also dropping in half each time and your 10 MHz clock no longer looks square. So not only is the capture rate affected by adding channels but the sampling starts to kill your clean square wave. This is one of the issues with both the 800 and 900 series. Also the vertical space for waveforms is very limited in the large utility bars at top and bottom of screen. For a wide angle screen - the menus should be at the side to maintain the vertical space for signals to be shown - after all isn't that what the 12 bits are for? ;) Thumbs up as always!
Perfect, thank you!
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. 😄
You can sell it on ebay today before most people realise :-D
@@EEVblog then I'd have to explain it to my mom lol
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..)
You can run it from a USB power bank for isolation. Awesome
There should be an auxiliary control screen for when you hook up to another monitor. Just more buttons and sliders on the screen.
One I got the HDO924S is the bus decode work on the digital channels, 0 to 15.
@ 32:15 Are you sure you have the Siglent set properly for the FM display? Mine looks nothing like the mess that you show in the video. The display on my SDS 1104X-E looks the same as on the Rigol for both of the FM tests.
how does the fan breathe when you use the VESA mount?? looks like it would block it completely
Does the 900 series have the OS installed on an SD card too ?
I think it is brilliant the Rigol did this. Can't wait to see some of the hacks that people do to the OS.
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?
Should I get one of these or keep my trusty old TDS3012 (with FFT option)?
I think I will get one of these to replace my crappy Hantek, the boot time sux but you get a lot of functions for the price.
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?
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.
Hello, thank you for this informative and entertaining video. I'm thinking of buying a Rigol these days, but I have a question. Is the product code HDO or DHO? There is only DHO on the website, but as far as I see, yours also says HDO? Is there any difference? I am confused.
Thanks.
Good morning Dave. It kind of seems like the button push when enabling another channel, triggers the math, dividing function of the scope. At that point the "connected" channel is divided by the enabled math function, rather than another BNC connected, probe's input signal!! MAYBE??
PLEASE tell me I'm right!!??
😋
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.
I have a question about the USB-C connector. Is that power input only, or can it do power input and data I/O on one USB-C cable? I don't expect it to do both power and data, but how cool would it be to just have one cable between the 'scope and computer, powering the scope from the computer with comms.
It looks and performs great for the price, but I'm keeping my unlocked 1054Z until it dies - so far going strong for over 7 years.
Spend your money on projects instead
@snap_oversteer, yeah, me too - even though I bought my 1054Z just couple of months ago (it’s all unlocked now standard)
Tempting. Is the fan annoying like Dave called out on the smaller model? I have desk space and money.
@@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.
do you think this is kind of the best option for a two or more channel general use scope? home hobby stuff like amps, diy computers, maybe automotive stuff?
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.
Why is the 942S a DHO? Should it not be a MSO? I guess i didn’t get there naming but it does have digital probes while the other ones has not.
