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.
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!
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 .
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.
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.
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.
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.
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.
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.
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.
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.
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. 😄
@@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.
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.
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.
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?
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.
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!
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.
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.
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?
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.
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).
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.
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!
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!
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.
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..)
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...
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.
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
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.
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 .
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.
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.
"46-47 second boot up is agonizingly long" . . . Looks at my vintage heathkit single channel scope that needs to warmup for 20+ minutes . . . Lol. I'd take sub 1min boot up with 4 channels any day. this is a great walk through. I've been looking something like this for a while
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,
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.
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.
I would love Rigol if they made a part that fits on the mounting lugs which would hold cables in place. I can see that USB-C port being the Achilles heal of the whole thing because it's probably going to break on a lot of scopes, people using the HDMI and USB ports will have similar problems.
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.
Ohhh man, I wish I could afford one of these... I've been shopping for an affordable scope for like a year and this baby has by far the best features for the price that I've seen... Guess I have to just hope the price doesn't go up between now and my birthday in a few months, I probably won't have the $$$ to spare until then cause I'm definitely getting one .
I'll be honest I am not too sure what I need nessesarily. I am currently taking a course on DSP in university and was just looking for an oscilloscope that I can go with and not shoot myself in the foot in the future with.@@EEVblog
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.
Since i have actually purchased one ,I m not so sure this should be publicised 😎 Rather abfab if you come from any greeneye 😙 wow !!! But the thing what got me was effortlessly show the sh*t on my way bigger monitor screen . just AWSOME.
It probably uses a digital trigger, that's why the sample rate lowers if you set it to a different channel. Doing the same with memory is very wasteful in my opinion though, I'm sure they could optimize that out and calculate the trigger point on the fly.
Seems it's time to upgrade my 1052e, for a reasonable price. [edit] what I'm not a fan of, is the fact of an external PSU, because I don't use my scope in a mobile situation. And if you have a few other things with these, it becomes a chaos. Same with pro-audio devices, because these are powered from a Furman power divider. But I understand why they do this, to cut costs. So each region in the world can use this.
I am new to oscilloscope but... the fact you can plug it with USB-C, is this mean you are protected for blowing up the oscilloscope when you probe on the wrong ground?
