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.

@jacquesgilbert2774 8 лет назад

+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.

@jacquesgilbert2774 8 лет назад

+Jacques Gilbert I mean 'scopes do not SELL by the millions.'

@breedj1 8 лет назад

+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.

@breedj1 8 лет назад

+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.

@petersage5157 6 лет назад

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.

@tubical71 8 лет назад

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'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.

@dollerstorehack 8 лет назад

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.

@electricsnut 8 лет назад

+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.

@oriole8789 8 лет назад

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.

@mosfet500 8 лет назад

+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

@oriole8789 8 лет назад

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. :)

@PeregrineBF 8 лет назад

+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 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).

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.

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.

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.
