Man, the user interface alone really sets this scope apart from the rest. I LOVE it.
+Luke Den Hartog that´s propper engieneering....;)
+simontay1984 A good UI needs to be designed. Software to implement the design will be expensive, it needs to be optimized to run well on a low powered computer without interfering with the scope functions, and it needs to be properly tested so it does not crash or, worse, display erroneous results in unusual situations. All that needs to be done by people who know what they are doing, it will take time and cost a lot of money. Scopes do not feel by the millions, so the software cost will add something not insignificant to each. If you are trying to get a device to market quickly and keep the price as low as possible, these are luxuries that you cannot afford.
+Jacques Gilbert I mean 'scopes do not SELL by the millions.'
+Jacques Gilbert Designing a good UI design costs a lot of money. You will need an interactive designer, a graphic designer, a programmer and a tester. They all spend a lot of time. So that's a lot of expensive hours to be paid. But of course you do not have to create a new design for every new scope. But bad or less good designs, compared to this one, like the Rigol ds1054z also cost a lot of money. But that scope still is cheap. Rohde & Schwarz are just not into hobbyist scopes. I like the hardware design of this scope as well compared to the rigol. The rigol looks a bit messy because of the grey lines around the button sections. That my opinion of course.
+InXLsisDeo I almost forgot about the Hameg division. But I'm a bit confuced about the scopes now. What's the difference between the Hameg HMO1022 and the R&S HMO1212? The price is more or less the same. The scopes look the same, have the same UI and have both a 2G/s sample rate and 2MB. I'm actually saving up for a R&S HMO1212. I think it is one of the best low budget scopes you can get now. Really fast and well thought interface with a clean hardware design. I akso like the latest video of Dave about the fast and good FFT. Compares with the other brands. I know its something between my ears, but if they turn out to be the same scope I would by the R&S version.
If Dave saw those solder-mounted BNCs in a lower-cost scope (Rigol/Siglent price range) he'd have rightly gone off about how solder alone doesn't provide enough structural stability for connectors that are expected to have a bazillion make/break cycles over the life of the product.
I'd love to see a video of the Rohde & Schwarz HMO120xx engineering teams watching this video.
Impossible.

Obviously you have not watched this video here. This is clearly a Rohde & Schwarz RAPE-VIDEO or as we in Germany say Ein Vergewaltigungsfilm.
Gewalt is already in the very word there. Is it not?
You are not very bright, are you? And, judging from your German comments on an English speaking channel also quite rücksichtslos.
I bought an ex-demo unit HMO2024 that was shipped straight from Germany by R&S. 4 channel, 200MHz for under 2k€. Been loving it
It´s the same thing as happened to the TV-sets 30 upto 20 years before....first these things had been filled with electronics, the last ones with picture-tubes had nothing in it besides a tiny board right on the base of the pic-tube which doin all the stuff in two components...a big PLCC and a penta/multi-watt which contains all the video driving stuff...
Now the same thing happens in these scopes....I bet in 10 years we have nothing but one chip and the analog frontend inside anymore....
I also remember the first MicroWave synth beein full of components on various boards - as the lastest incarnation just had an nearly all empty 2U rack mount with a power supply most right and a 80x100mm multilayer PCB on the leftmost....went out with the same prizeTag on it, of course....;)
I understand why they do it, but it feels wrong to pay 700$ just for a version where the software has a value that says 300 instead of 100
Great info Dave. It shows design choices made to produce a great scope. Your tear down videos perform a great service for engineers as well as teachers of product design. I never get tired of it.
Super videos.
73's 9M2SN
I'd say the reason the fan is on an angled tab is to put a bit of space between its blades and the case grille to reduce/eliminate noise at the fan blade passing rate.
i count it out : 76 times "realy nice" and "thumbs up" and "great" and "nice" , " gourges engineering" , "the best"- 2 and Bob´s your oncle" smash it out Dave! i like it, thanks
Yep, that really worked. It was shipped a few weeks later... :-)
Yolo, Siglent will be making a scope just like this soon for 1/3 the price since they didn't have to do all the engineering.
Yolo, I would probably buy that
Does anyone know why my posts cause other posts to be backwards?
+jak p (skiguy09)
yolo, I concur, but there will be rust on the frame and firmware is going to suck
You guys! ;)
+jak p (skiguy09) YOLO, and they gonne put a nordinary fan inside, just smashed on +5/gnd..which soon went loud as hell...but we know it´s like YOLO...;)
Although obviously this scope is going to have excellent performance etc, I can't help feeling that like all other modern era scopes, it looks toy like compared to old school CRO's! The high end CRO's just looked serious and truly carved from solid!
May the Schwarz be with you.
+Mari Onette Schwanz, sir! Schwanz!
+Thomas Coughran Make sure you pay attention to the Rohde ahead.
I guess the fan is at an angle so you can't short it's air supply out by blocking the vent holes in the case?
Or the fan leads were a bit on the short side...
It’s probably to step it away from the plastic grille of the outer cover to avoid an air rushing noise.
made in the czech republic, just like the best porn in the internet!
+Fekete Imre spot on bro
+happy543210 And how are you aware of this?????
+happy543210
like PZ-IV
when quality counts, give her the kronor
Would have used Prusa as an example but just have to take your word on it.....
You've never sounded so in love like this time!
9:40 I've seen Clive tear down cheap eBay crap that has marshalling boards; other than the via stitching, there's really nothing special about that board bolted to the power supply.
So I am confused, now it is ok for them to use spade connectors for grounding but in the other review you wouldn't leave it alone saying it was poor?
+electricsnut I agree. Even though on this gear the spade connector is done right, but if it had been another manufacturer Dave would have said he preferred a screw and shake proof washer.
+Jack White Yup, while I do enjoy these tear down reviews... I can pick within the first 5 minutes which way any of these reviews are going to go. Dave seems to form an initial option about a product immeditely before it starts and that guides his attitude through the rest of the review.
+electricsnut This and exactly this. I like these but it's kinda annoying to watch him being so biased.
We should ask Dave to tear down a Mercedes or BMW.
For my part I'm happy to be subjected to the bias of a man with Dave's knowledge and experience. Unbiased opinions are only useful in textbooks as far as I'm concerned.
8:39 - 'Fess up, David. That shielding is to keep the electrons from falling out!
0:49 The worlds first DSO that can play UA-cam videos ;)
Seriously though, give it 10 years and it wouldn't surprise me.
The Atmel SAM says in its datasheet that it has a 400MHz to 1GHz PLL for the system and a 480MHz PLL for USB. So R&S could be using the system PLL to drive the PLL chip for the ADC Clock.
The crystal is probably inside the Altera module if it's a packaged module, not a single IC.
Only two channels is really a bummer when debugging a signal path. Three is really the minimum.
Great tear down Dave and thanks (as always) for taking the time out to look out the data sheets, always fun to pause and catch up on what the specs are.
Scope looks really well designed, BUT I don't like the ultra-bright LEDs behind some of the buttons. It looks as if they're going to sear your retinas. Also, the slope LEDs are bleeding through into the trigger indicator LED. That's not so good.
lol who downvoted this vid already? It's as if there are people who specifically use their time to watch videos they don't like.
I didn't really have any expectations for this scope since I'm really lusting after the RTO series from R&S, but wooow honestly very impressive. So impressive that I think I may actually get one. The small form factor, silent fan, ultra fast turn on time, and the brilliant UI... so nice for jobs where you move the scope around a lot. High-res modes and all the "visibility" options are great. 2 channels is perfectly fine. Also neat to find a Cyclone 4 inside; that's one of the beefier variants with extra IOs. I enjoy working with Cyclone 4's and 5's, nice chips. ISSI never disappoints either. Great job Dave and thank you for your work as always.
+whatlions
I'm not as gaga over the fan. Any high end instrument should have quiet fans. I complained to Keysight about the noise of the 34410A, it had this incessant wine, but the 34465a is so quiet I have to strain to hear it.
Rob
mosfet500 Well to be fair the degree of necessary active cooling depends on the instrument. This is a relatively low end unit and doesn't have significant heat dissipation (note the lack of heatsinks on the chips, even). High-end oscilloscopes are all super loud, and it's not a matter of fan brand but just the requirement to move enough air due to massive combined heat dissipation of various parts. That said, R&S still has to be given credit for efficient software and hardware design, so that all temps are low enough to allow the fan to spin slow and silent. I will agree with you that if the instrument is relatively high-end and can support slow fans by design, then there's no excuse for not making it as quiet as possible. :)
+whatlions Also size. A larger instrument can have a larger fan, which can turn at a lower speed to move the same amount of air. That helps keep things quiet. Small size is currently more in fashion than quiet operation, so many designers sacrifice sound quality to get the size and weight down.
I need this, but without any software bandwidth/sample rate cripple "features". Beauty! Could that empty internal space hold a "glove box" for probes/leads/accessories?
+FindLiberty It could have!
Would love to see teardown/review videos on the R&S RTH Series Scope Rider Handheld Oscilloscopes.
I love R&S. They are a very conservative proper German engineering company, I believe it is still owned by the original founder(s) families. They can be difficult to deal with sometimes - but their quality is difficult to beat.
I use a ton of their stuff in Broadcasting (both processing and measurement equipment) and it's just bullet proof. The main reason why we sometimes spec out other vendors is budget, otherwise if the client can afford it we just set and forget it (well as much as it is possible for today's digital tech).
the slope leds could use some dividers to stop light bleed
Love your channel - and actually you gave me the inspiration to start my own channel.
But Dave, this video confirms your love for the money scopes where you ignore things you bash on others. I watched your Instek review, then this one - and you white wash characteristics that you scoff at on the lesser dollar scopes. Like all the open space in this one. I make this comment because I like your channel so much. Thumbs up anyway;)
I just like the fact that it has the older analog oscilliscope dimensions :-D
Yes im an old bastard lol.
I really like the step by step on screen guides. It's very un-German of them to do. It's between this and the Keysight for my next oscilloscope.
would you mind to consider to show what happen when you try to analyze a 5.8 Ghz wave signal with an apparatus like this one ???
Logic inputs look like they may already be LVDS - is there an external active probe?
+mikeselectricstuff Keep watching.
+EEVblog It's exciting to watch and hard to keep the fingers still until it's finished.. happend to me sooo many times
What a scope !
Hungarian cooling fan :)))) Yeeeeeeeah! Well done eh? Greetings for all Hungarian visitors :)
+BMR Studio Similar to the whole device. Papst (now ebmpapst) fans engineered in Germany, made in Hungary. Even back around 1990 when I assembled my first computers, Papst (engl. "pope") fans were the top brand.
Hungarians are good on assembly. They like the German precision.
+BMR Studio One of them looking the video right now :). Didn't know we had such a great fan brand made in our country. I was just looking for a good 4 cm fan for my front side bus, but I think I got the brand :). May get it cheaper, but I doubt it, might have to get it from China or something on ebay :(.
+András Kiss Remelem tudsz kapni Magyarorszagon :)
+BMR Studio Do they make fans for PC and CPUs?
Fab teardown Dave. Fascinating stuff, and what a gorgeous piece of engineering design.
Hi Dave! Video --- beauty!
I am kind of curious, do you wear ESD protector ESD strap while doing the teardown? Why don't you mention before the video that this is important, lest people would love to kill their devices? :) Thanks!
If their low-end scope is like this I wonder how their high-end scopes look like. Dave contact Rohde & Schwarz and ask for a high-end one to teardown/review.
+InXLsisDeo And seeing it being constructed in the factory is even more mind blowing. This is what I call science
Excellent video, but I would have liked to see the duty cycle on the "quick view" feature...
I liked the aesthetics of the R&S scope.
you always complain if the ground is not held down with nut and shake proof washer but was happy with spade terminals?
There are so many cool little touches on that thing that just show you why your paying that extra, Wonderfull.
The UI is nice, i still see a few things that need to be improved the highlighted items are a bit high contrast , little bit of wasted space at the bottom , but compared to most things its top notch.
In the beginning of the video, when I saw the price i was like
"It better give some value for the money... god that's expensive!"
And hmm... it does. If you consider that it's going to be used in production environment where time's money etc.
For hobbyist... no way :D
Dave, do it! Get some batteries inside this puppy :D
+TheSecondFunnyKing I've been considering designing a battery option for the DS1054Z.
+TheSecondFunnyKing indeed! must be done.
Something like this might be an option?
www.altex.com/12V-Lithium-Ion-Rechargeable-Battery-Set-LBP-124500-P150057.aspx
4.5Ah should be sufficient to run it on a fully charged battery for a few hours i presume.
Heck maybe able to stack two of these in there, seems to be enough space
+EEVblog make a video about it, would love to see your process going into these kinds of things. this is exactly the stuff i subscribed for.
Definitely looks like a well designed and well built scope but I wouldn't go as far as saying it's 3 times better than the Rigol to justify the price difference :) It probably is more a matter of choice (when money is not an issue)
Well jelious of you Dave. These companies send you excellent gear to play with. Do you ever get to keep them or do you send them back after you're done?
+Steven Choi Some I keep, some I send back. This one is technically on a 6 month loan, but they might eventually just write it off.
You've been in like Flynn it should be worth twice as much now
+EEVblog hahaha me thinks only if Richard gets very very drunk..
@@EEVblogTo be honest, i ressent these companies sending you free expensive equipment, it's just not fair for the rest of us. I understand they'd loan it to you or give you a couple hundred dollars vouchers but free ?! That's just wrong and makes me think i'll pay for your free scope if i buy one and makes me not want to buy from the brand.
Neat little beast. Like GUI too. Most of vendors kinda skip GUI importance, so R&S is nice refreshing break of this "rule". Used R&S siggen before, UI was great too.
Ahhh
R&S HMO1202. That's going straight to the pool room!
Is it just me or are the teardowns of junk and scrap tier devices more interesting than well made ones?
As you don't read/reply to pm, I hope you get to read this at some point.
I love your "Teardown Tuesday" especially the "671 white van speaker scam teardown" and I hope you make more Teardowns :)
It's great and interesting watching what's inside this scope. The only thing that bother me a lot is those important parts that is made in CHINA. Once you utilize those parts the scope will be a cheap and undependable machine as a whole. I'm afraid to have this brand.
Thanks for this, Dave. Have you any feedback on the RTC1002, please?
Good stuff. Little bit older components base, but design like a for always.
R&H still the best.
at 2:29 - Just under the handle there is a rectangular piece of plastic with what looks like finger grips. Any idea what those are for?
+cemx86 It's a space for interface modules. For instance, the 1022 comes with the USB/RS-232 remote control module HO720.
I think the way the fan is mounted looks bad. It looks like they did that way to compensate for the short fan leads. If this were a UNI-T that would have been made fun of for sure. I like the fact that they put the power supply in the metal box. It is nice and neat.
Didnt know Rhode & Schwarz has a factory over here in CZ.Rep. And greetings to Hungary for a nice fan and also other nice stuff coming from Hungary...
Whoa - did I see gigafarad caps on that line trigger section of the PSU daughterboard?
Hello, I didn't know that there are scope manufactures in the Czech republic, although I live there 😊
for a LOW COST unit i preffer the rigol to be honest
i dont buy entry level from big brands, neither upscale products from low cost brands.
Simplistic means treating something complex as if it were much simpler than it is - I don't think you meant that when describing the front end.
Awesome video!
10:18 Fan made in Hungary. Hi Dave, from Hungary! :)
Interesting that the name label on the scope has the same font as Agilent/Keysight gear...
Thank you. I love your reviews.
This scope seems great. Almost makes me want to trade my DS2072A Rigol for it. Wish you touched on the LA decode options.
This scope makes my pants tight Dave. Very tight. Might have to get serious about getting one.
i don't like soldered "golden" bnc's, saving on proper main board shielding, loose wires from display connector (actually all wires in airflow path), psu pcb's, front bnc and trigger control layout without color coding, even case cover fixture does not look strong, triggering issues. But what really kills is NOT pushable vertical and horizontal position knobs
I'm a bit stumped with the function generator on this unit. I'm trying to calibrate a selfmade series 500 microphone preamp (it works - just needs final gain and distortion calibration), but for some reason I'm not able to output a standard sinewave 1kHz signal using the aux output and a bnc to xlr cable... what am I doing wrong? I've crimped the bnc connector to one end (red/signal to center pin, ground to crimp barrel) , soldered a male xlr plug to the other and bridged pin 2 (red/signal) & 3 (white/inverted signal) while having my ground connected to pin 1. No matter what I try, I can not get a reading in my daw. Maybe someone can give me an idea of what I am missing here.
I put these videos on loud when I'm surfing pr0n...nobody in the house would ever guess!!!
I think Dave should tear down a mid tear scope from R&S. Tearing down this low end model proved little.
and until today I rarely/never sees Dave utilize this DSO in most of his vids
You realize that Rigol is a cheap Chinese scope when you use a Rohde & Schwartz
>Dont turn it on, take it apart
>turns on
Why teardown the crown jewel of instruments ?
No review? So many teardowns in a row are getting old fast.
Very very nice Scope
Hi Dave, just took a look at this, I see the "HM" infront of the model number, following HAMAG tradition, I know R&S took over HAMEG for sure this unit is VERY tidy inside & designed very well :), impressive unit, cost is humm a little high in price I personally feel, knowing how cheap the early "HAMEG range" was when it was HAMEG. but I guess now its R&S, the only thing I hate to see is a battery on a PCB, leakage can cause big problems as we all know, perhaps a buffer to the FPGA from the outside world might have been better protection for the FPGA ?, only personal preference would have liked to see nuts on the BNC to prevent less movement on the PCB joints,
Maybe I am way too late but as far as I Know, the Coin cells have non corosive liquids in them and the leakage is minimum even after a lot of time
flamin ell dave i damn near choked on my potato waffle when i saw the price of that!
regarding the "best design and built scope I've seen", you are wrong, you've seen a similar design in your Agilent 4000 teardown :) you were asking to let you know if you're wrong :)
Which camera did you use to make this video? Close shooting of PCBs is brilliant
I have just been reminded that on youtube you can not only add subtitles yourself but have the ability to enable other people to send in (and approve) subtitles in other languages. Do you think that might be an idea for viewers not so fluent in english? You can probably retroactively enable it for older videos too, I am sure lots of viewers are willing to spend some time adding subtitles in their native languages.
can someone tell me what knind of diode emits light (but not LED) . It's inside a stereo amplifier (there's about 5 of then in different locations)
+kiss peter Sometimes LED's are used as voltage references for certain power rails (normally rails feeding op-amps). Certain LED's can be less noisy (and cheaper) than equivalent zener counterparts.
So it is a led ....well it emits light , but i would have never guessed . Thaks for the imput .
At 20:00 you can see a lot of wiggly PCB traces from one of the sockets. Why did they do that? Why not just a straight line?
+MacPhantom Its for timing. Keeping the trace lengths the same.
+Ron Shaw Excellent; thanks a lot for the explanation. Makes sense if you're dealing with these kinds of frequency ranges.
Wooo! Finally, they didn't cheap out on the fan or the PSU and capacitors! Smexy XDDD
surprise another oscilloscope tear down!
Line triggering generator board won my heart
One minor, maybe even non-gripe, why the soft start button. Everyone and their puppy knows that's the thing to have in terms of feel. I really dislike soft buttons lately. At least if they'd use better rubber for the buttons.
Wow, that fan was made in Hungary, I have something to be proud about now XD
Could it be possible to get a video about essential lab tools?
Weren't you against the fan sucking in air, getting everything dirty inside?
+ChillCosmos I don't understand Dave's preference in that point. In my opinion it depends on the thermal design and how to control the airflow through the system. For example In a dusty environment you can place a filter in front of the fan inlet. That's much easier to do instead of sucking in the dust at undefined openings.
Hi from Czech republic too!
Dave's job is actually freelance salesman / advertiser for these brands, Litteraly speaking.
Great teardown. Makes me wish I had $2000 for a scope!
Hello. Please help in choosing between:
OWON XDS3104AET
Rohde & Schwarz RTC1002 MAX
Rigol MSO5074
If I had enough money, I'd always buy a Rohde & Schwarz. They have now a good offer, a RTC1k-COM2 Scope with RTC-B223 300 MHz bandwidths upgrade for a few bucks, at least here in Switzerland for CHF 1500.--. Google it.
Czech Republic rules! :D
Hi to you too, Dave. :)
+VitekST - Vlogy, programování, ... You may know a company called MEATEST. Pretty nice calibration stuff made in Czech Republic.
+Chip Guy Vids Yup, I know about them quite some time, although I am a kid, at least from info what's online, they make great stuff.
Question, is the filter setting something like a software defined band pass filter ? because that would be kind of cool; though I can't think of a use for it but it sounds cool XD
This would be nice for embedded programming i guess, and looking at your digital communications, does one save their money, skip the rigol and buy this to go with their jbc soldering iron. Does the miser pay twice?
Dave, that tune you're whistling during all fast forward stuff, is it indiana jones? :D
Dave,
I'm also impressed with these scopes. I just looked at the HMO3032 and they include bus decoding - very nice! But isn't R&S now owned by Hameg?
Rob
+mosfet500: little Hameg was purchased by huge Rohde & Schwarz
+mosfet500 No. R&S integrates Hameg since around 2012 and finished it this year.
+WattSekunde
OK, so this and things like the HMC8043 triple power supply are really low end R&S "value line" products. Who's designing them Hameg or R&S because if you look up Hameg they show this scope?
Rob
+mosfet500 Design as well as production and service are all done by R&S now.
+Rohde Schwarz Thanks for the info!
