A few comments: - At 14:04 mark, the component is a solid-state relay which can shunt the AC input capacitor for DC-coupled high-impedance input setting. - Channel-to-channel matching means matching the phase & frequency responses (which includes signal polarity); every via, every trace length and proximity effects all matter. Even though 2GHz is not a very high frequency, the board material can have a big impact. - There are still features which R&S will add to this scope over time.
Great to see the 45k FFTs in action doing something useful. We forget that you are running this demo over web control. It’s just crazy fast and seamless.
For RF measurements, the scope was set to auto mode.....if a user changes trigger to "Free Run" the scope updates even faster. It's a very cool RF feature that R&S has that no other scopes have. Autotrigger will wait for 50 mS and if it doesn't find trigger, the scope will capture. For FreeRun trigger mode, the scope doesn't even attempt to find a trigger...it just updates as fast as possible. This is great for applications like RF and power integrity where an analog trigger isn't needed.
If you can find a way of making the price of the $8,000 FPGA drop to a couple of dollars and other custom parts drop significantly in cost, yes. Otherwise it is what it is. My bank account cried when I bought my MXO-5. In fact I think it's still crying but I don't regret my purchase. It has completely changed the way I troubleshoot RF circuits. I haven't owned it for long but it's already come close to paying for itself.
Really appreciate the content. I wouldn't know how else would one be able to see this high-end machines in practice. Quite unique. Not to mention the educational side! Thanks for the effort.
Thank you Shahriar for the outstanding review. I already liked the MXO-4, but I'm blown away by the MXO-5. One more item added to my wishlist. Keep up the god work.
Nice to see something other than ENIG in a high speed board. Looks like immersion silver or tin, presumably to avoid the skin effect losses from the NiP layer in ENIG.
It blows me away that for something this large it was not decided to separate the front end, ADC and compute in to three different modules (plus each front end being a separate module) for binning, higher yields, repair, and just the logistics of it all but they seemed to pull it off fine and im not one to question R&S
Good remark, the only way to repair this scope if you blow up one of the inputs is to replace the whole card, which is as good as buying a new one. You certainly can question R&S on this.
It's pretty hard to get connectors and/or cables between sections that run this fast, easier to use good (VERY GOOD) PCB design to get the job done. Sadly, it is a downside that repair is "non-trivial"!
Fantastic video and features, the zone triggering is a new breakthrough I think especially when combining in time and frequency domain. R&S really has great instruments. And R&S is here in munich next to my location, I was doing a practica many many years ago when I was studing at the University (TUM) and at that time it was great what they were doing.
Shahriar, the I and Q example showed both the complex capabilities of this awesome piece of hardware but also how the volumes of information could be derived from the analysis tools and all in 45 minutes. BZ
love the videos been watching for a few years. would love to see video about noise figure measurements/theory or measuring amplifier stability with load side tuner, smw, fsw!! Love the instruments that you cover btw
Very helpful video, thanks ! I happen to be considering an R&S MXO-4 right now. Are the basic features about the same w/r to setting up triggers, arranging windows and using FFTs etc ? Obviously some of the specs are different. Thanks !
At the contrary of what Tek made with the MDO4K, you're now obliged to go for an analog BW that meets your RF needs (if any), which can be pretty expensive. Yet, what a great piece of equipment !!!
Ooh, I like the channel grouping: you can activate 1,2,3,4 without dropping the sample rate, rather than the goofy "odd channels then even channels." Since the long traces come after preamp, it probably doesn't even have much of a noise figure cost. Very cool!
A scope, a spectrum analyzer, signal gen and some logic analysis all combined together, the result of super integration. Its really magic for bleeding edge design work. This is where the electronic design has been trending for decades. I have a hobby lab with equipment that was this expesive in real terms years ago. In twenty years this will be standard functionality available from multiple vendors. Yea, nobody pays 6k for a chip in production 'cept the military. Yield? Burn in? Not very repairable though.
Hey Shariar, nice review. I really like the zone triggering. On the DFT side what windowing function did you select in your demonstration? Just wondering how big the software development team is to create this marvel of engineering... Any news on your microscopy endeavors?
Hi! I hope you are doing well. I managed to get a new set of lenses after lots of searching. So the microscope now produces very nice, sharp images. There are some prisms I am still missing for proper DIC, but slowly I am working through them. :)
Nice job reviewing this great piece of engineering, Shariar! Thanks a lot for the effort. But there's one detail I dare to differ: The BNCs are't screwed in onto the PCB for rigidity -- ideally, the PCB shouldn't bear any mechanical load of the attached probes / cables. For this purpose, the BNCs are screwed/bolted to the surrounding metal chassis structureal components by their central ring nut. The screws that attach the BNCs to the PCB are rather intended for easy replacement of the BNCs in case they wear out or get damaged otherwise. A BNC that's soldered into a multilayer PCB with a lot of copper in it by four massive ground prongs can hardly be removed without high risk of causing damage to the PCB. In this R&S Scope, you just unscrew the two/three screws and unsolder the signal contact which hasn't got high heat capacity, and your're done without any significant risc of causing collateral damage. That's a very clever approach to protect the high-value PCB in case "peripheral" repairs are required.
Thanks, I thought I had kept that section in the video, but it looks like it got cut. Indeed the problem is how to maintain a good mechanical connection without soldering the ground plane of the connector. With the screw, you need a pretty good interface without even a micron of gab between the connector and PCB to ensure a good, low-RF-leak transition. But as you said the advantage is that it is much easier to remove the connector if it gets damaged.
How do you have the time to be: Head of Bell Labs' ASICs & Packaging Research Lab. Bell Labs Fellow, Adjunct Professor at Columbia University and also do tutorials?
Some people just seem to have either more time on their hands or an incredible drive to do thing and be successful. He seems to fall into both camps at once lol
14:49. I believe this layer switch is not so much for length matching and number of via matching. I believe it just switches the positive and negative signals around. Probably because of the placement of the ADC input pins. As a layout guy the connection between the frontend and the ADC baffles me. The way each ADC takes in signals from channels that are 4 channels apart from each other is just bizarre. Usually when you have 1 ADC per 2 channels, the ADC sits between two adjacent channels. The only logical explanation i can come up with is that they wanted to have the same number of ADCs on the 8 and on the 4 channel version of the scope. Maybe for software, noise or some other reason I'm missing. I'd love to hear suggestions on why that could be.
Damn, this baby starts at $50,000.00. Geez! How many of these are they going to sell ? 10 @ $500K, 100@$5Mil ??? They must expect much more than that, otherwise I don't think they can make up the R&D for this monster. Seriously. R&S, @TheSignalPath, any comments here ?
I don't consider them that expensive. I recently bought one and it will easily pay for itself within a year. Mine arrived at a perfect time to demonstrate it's worth. I had a public service digital transmitter I was working on that had me stumped for over a day and a half. I just couldn't find what was causing the glitch. My MXO-5 got delivered and after acquainting myself with it's operation I found the problem in 15 minutes using the zone triggering feature. All I can say is, God, how have I made it this long without one.
@@mikesradiorepair Mike, I have no doubt that the scope can find a cure for cancer. Just kidding but I am also very serious. My comment is more along the lines of: "How many people really need this insane functionality AND can afford it". I am just curious at how many units will R&S can sell to make up for what must be an very expensive R&D. The way I figure it, they'd better sell 1000-5000 units before it makes any sense. On a side note, I wonder what the price for one of these will be on eBay in 10 years. Cheers !
You can also adjust the screen trace brightness, to get a better sense of how common/seldom the anomalous events occur, since some triggers are just synchronization of the waveform vs. Horizontal setting.

The PCB trace "wiggles" are probably to ensure that the 'signal path' lengths are identical, not just via count matching, but timing, too. Them R&S design guys know a thing or two about 'signal integrity' 😉, right, Frank?
Given the volume they are likely to produce I would be surprised if they are paying more than 400/800$ for that FPGA, it is notorious that amd/xilinx and altera do not want to deal with support and distribution for low volumes so they structure the prices accordingly
@@AlpineTheHusky I am not saying they will not sell them for one off, they obviously do... However the pricing model is designed to discurage low volume usage of FPGAS as much as possible. This is done by applying an extremely high markup to the one off pricing (much larger than for MCUs or even regular CPUs) however if your volumes are high enough to be able to speak directly to AMD/alter (i guess 10-50k units per year bare minimum, maybe more) the price drops to a fraction of what it would be, much more than for other components with comparable volumes. The effect is so large I can say with pretty good authority that for even medium volumes for high power static converters (DC/AC, DC/DC, etc) BOM cost is not a factor in the choice of FPGA vs MCU when designing the hardware as the cost is fairly equal ( we talk of lower end fpgas obviously) expecially when you start to consider how much money the better characteristics of the FPGA based control (lower latency, higher frequency, oversampling, etc.) can save you in capacitors, inductors, etc.
@@AlpineTheHusky The problem with FPGAs is that the public pricing is completely fake, you have to negotiate on a case by case basis, either with the official distributor, or with the manufacturers themselves to get the real (and much lower price) also they will want you to set up procurement agreements where you sign a legally binding contract to purchase a set volume of chips per year for a set number of years, before they will bother working with you. Do that an I can guarantee the prices will go down massively, however (and this was kind of my initial point) all of this is too much bureocracy if you want to do a one off low/mid volume production run once in a while, as such fpgas are only used in few markets where these conditions are met (defense where buget is not an option or telecom where you have high enough volumes and the flexibility justifies the higher price compared to an ASIC, or similar) Also for FPGAs 1k per year is barely enough to get on the distributor radar (forget talking with the manufacturer, not enough volume), so the price will not come down by much (i would say only a factor of 2/4)
As far as design, they still don't use the very useful texture and colour differences for function groups, like trigger, horizontal, vertical, which Tektronix used to good effect on the "good old" 465/475 scopes.
@@Thesignalpath 8 Channels are often used in power supply applications, that Rigol is good enough for that. The R&S is superb, but the price for 500Mhz is 35k€, no prices in € for the Rigol yet, but I could get a pile(3-4?) of DHO5k for that? I had a Rigol 7k and a R&S RTB 2k at my former employer, the 7k is noisy, but it is damn fast and the case + cover are superb. If the noise is not an issue, which it is not for a lot of embedded engineering, the Rigol 5k is amazing, 8 / 2GSps for all channels! Combine it with a DHO8, 12Bit much lower noise any you cover 90%+ usecases, you could hook up a USB battery for mobile applications.
Getting a “pile” of something doesn’t change the class of the instrument. Buy whatever that suits your application. The R&S 5-Series, Tek 5-Series and Keysight MXR are competing at a different level for many reasons - that’s the reality of the instrument performance, features and applications. Not sure why you feel the need to justify your purchases - if it works for you, great.

Nice! Does this one have the cycle-cycle jitter measurement? That's missing in the MXO4
One huge issue with this design: il you blow up an input, you need to replace the whole board. A $40k main board...
if you turn on the statistics for a period measurement, isn't that the jitter?
14:04 that's not protection, it's the solid-state relay to select AC/DC coupling, shorting the big capacitor next to it.
Yes! Thank you.

@@pelor92 Look at LCSC or other big stock sellers of ICs. FPGAs are still hellishly expensive even at 1k units
@@AlpineTheHusky The problem with FPGAs is that the public pricing is completely fake, you have to negotiate on a case by case basis, either with the official distributor, or with the manufacturers themselves to get the real (and much lower price)
also they will want you to set up procurement agreements where you sign a legally binding contract to purchase a set volume of chips per year for a set number of years, before they will bother working with you.
Do that an I can guarantee the prices will go down massively, however (and this was kind of my initial point) all of this is too much bureocracy if you want to do a one off low/mid volume production run once in a while, as such fpgas are only used in few markets where these conditions are met (defense where buget is not an option or telecom where you have high enough volumes and the flexibility justifies the higher price compared to an ASIC, or similar)
Also for FPGAs 1k per year is barely enough to get on the distributor radar (forget talking with the manufacturer, not enough volume), so the price will not come down by much (i would say only a factor of 2/4)
Oh oh someone forgot to put the back button in the zone trigger... OHHH MANNNN!

And here I am trying to resurrect my 30 year old TDS360, after it's nvram battery went flat, because I can't afford an new scope. 😢
As far as design, they still don't use the very useful texture and colour differences for function groups, like trigger, horizontal, vertical, which Tektronix used to good effect on the "good old" 465/475 scopes.
*starting at* $17600 😬🤯
i want one pls
Thats way to cheap. That must be extremely cut down. His model is closer to $70k
@@AlpineTheHusky I KNOW 😭😭
@@k1ngjulien_ Get a Rigol 800 or 900 series and be happy :D
I cant even imagine how you would ever use up 600000 logic cells.
Damn, I bet it’s going to be a lot more affordable than our Tek MSO 3 & 4 series, too. Can’t cost $40k surely.
Damn, literally half the price of our products. Wonder if they’re still engineered and manufactured in US.

Rigol DHO5000, 8 Channel, 12 Bit, 1GHz, Battery Option,...
Completely different class of an instrument and naturally cheaper.
@@Thesignalpath 8 Channels are often used in power supply applications, that Rigol is good enough for that. The R&S is superb, but the price for 500Mhz is 35k€, no prices in € for the Rigol yet, but I could get a pile(3-4?) of DHO5k for that? I had a Rigol 7k and a R&S RTB 2k at my former employer, the 7k is noisy, but it is damn fast and the case + cover are superb. If the noise is not an issue, which it is not for a lot of embedded engineering, the Rigol 5k is amazing, 8 / 2GSps for all channels! Combine it with a DHO8, 12Bit much lower noise any you cover 90%+ usecases, you could hook up a USB battery for mobile applications.
Getting a “pile” of something doesn’t change the class of the instrument. Buy whatever that suits your application. The R&S 5-Series, Tek 5-Series and Keysight MXR are competing at a different level for many reasons - that’s the reality of the instrument performance, features and applications. Not sure why you feel the need to justify your purchases - if it works for you, great.
This is absolutely nasty.
At this point they should just pay you to do their advertisements...
