You know you've made it in life when Keysight will send you something like this. Not only the device but boards and decapped chips. Absolutely stunning.
10bit @ 113Ghz and 4 channels, I just can’t wrap my mind around that! Thanks for the video, no way I’d ever get to see one in use otherwise. I work with ultra low frequency stuff usually 10Ghz or lower so I guess that’s basically DC these days. Amazing.
What an absolutely incredible engineering achievement. It takes a very special company with a wide range of talents and a wide variety of fabrication technologies/abilities to make a product such as this. I can only imagine the pride and accomplishment felt by the team who were fundamental to this device's creation. Great stuff 👍
That is by far one of the most amazing things I have seen on TH-cam. Being able to actually see that high frequency sinusoidal waveform, wow! That is serious engineering in all electronic voodoo disciplines. Thank you for doing this video, and you are correct, the engineers that designed this should be very proud.
You seemed extraordinarily comfortable waving that metal pointer around that million dollar oscilloscope's screen. If keysight had dropped something like that at my doorstep I would be afraid to even breathe near it.
I'm amazed that Keysight is letting the world see this equipment in such detail. Typically I would expect something so pricey and niche to be kept under lock and key. I can't believe all of that is required for a SINGLE channel of the scope. Absolutely incredible engineering. Totally worth every one of those 1.3 Million dollars.
Shahriar, every time i sit at my desk i feel good about what i have there about a house and a half worth of equipment and then i watch a video of yours.... takes me two weeks at least to recover from the shock
The PCB assembly alone is extraordinary. That A/D PCB must have taken a lot of planning and consideration for assembly, reflow, testing, etc. The design......obviously next level. Stunning opportunity to see technology like this.
I work as an engineer in a small company. Usually i do both schematics and layout (like i said small company). I would LOVE to some day layout a board like the digital processing board on this thing. It looks really fun to do. I wonder how long it took.
You would not be able to get me to even look at this thing before i'm convinced that my ass is fully covered, insurance and liability wise :D I did not expect to be convinced that this machine is reasonably priced, and yet I am. Stunning stuff. Thanks for sharing.
Man, that board design.. incredible. I'd love to just look at the routing. Of course the indium phosphide design is next level awesome, and look forward to other foundries opening this technology up. Huge props to Keysight...
Maybe a university or professor discount. Most of these high end instruments don't sell for MSRP, almost always negotiable for any business looking to aquire one.
Great video. Would like to see some applications which have demand for this type of equipment. Hope KS lets you have it again for some experiments once it is in production.
Holy fucking shit, this thing is glorious. Every different board is a treasure of different engineering techniques. And kudos to keysight for the samples, I bet the people that worked on it would be happy to see someone gushing over it. And at this level you could take hi-res photos of each component and sell them to other companies, and yet they wouldn't have a shred of the technical know-how to produce this beauty.
I think that was the one I saw at the NIST antenna lab, along with a down-converter from Rohde Schwarz to bring the antenna's transmitted frequency down to something the Keysight scope could see. I think they said they could do work up to 300 GHz.
In my lab we have two URX Scopes 128GSps, they are not as fast as this one on the front-end side, but still impressive (the fastest is 33GHz). My opinion after 2 years of use is that they are undoubtedly amazing machines with excellent front-end and DAQ hardware. However (and I honestly hope that some Keysight colleagues will read this comment), I would have expected just a little bit more on the software and UI in general. I'm not saying that is bad, don't get me wrong. But we are talking about million dollars machines, I honestly would like to have the absolute best. In particular, I noticed that the stability should be improved, expecially while CDR or heavy measurements/math are used. In several occasions I had to forcefully restart the OS due to hangs. Furthermore, I'm sure that the UX (including responsiveness and even interface style) could be enhanced: controls are slightly less prompt than on the old infiniium scopes (which I loved, especially the 20 years old ones with that DAQ to GPU waveform bus
@@Sebas_Cba_82 I reply in English. In my team we develop solutions for high speed data links, including design of serialiser/driver ASICs, Si Photonics modulators and the relative integration modules. We currently target about 26Gb/s per lane. Hence, the UXR represents a valuable tool for the characterisation of signal integrity in such devices. We mainly use it for eye diagram testing and wide band phase noise analysis. These are quite common applications of the instrument. If you work with COTS transceivers, it is generally not required to own it, since those are originally qualified by the manufacturer. Good SI design methodologies and simulations are enough in that a case. The RTA features are instead very interesting in a variety of designs and test-benches involving RF signals. However, the purchase of a spectrum analyser could be discussed if time domain analysis are not required, this would probably allows spending a bit less.
Just for some perspective.. you can capture light traveling less than 1mm with this puppy. That is a fast time domain. Useful at CERN. Probably overkill for weapons research :)
No word of boot time, fan noise or tap test on the inputs. Also I bet serial decode will be $800 optional extra! So I’m holding my purchase for now. :P
Wow! What a absolute beast. Guys, if you want to see things even clearer then you can use a magnifying glass in front of your phones screen. It works really well. Thanks for the awesome video. =)
And how do they test the 110 ghz signal generator when they need the signal generator to test the oscilloscope but also need the oscillopscope to test the signal generator?
my question is similar, do you already have a better specs scope or instrument that was used to design this and is just for internal use? or develop this using the same tools that you already have for sell?
28:00 Interesting to see that the base of these dont seem to be ceramic but ordinary PCB material? Dont think I have seen that before, but it would absolutely be cheaper though.. for them that is.
If you're still around in 25 years or so, Siglent will put this on your bench for $1M, which by then will the equivalent of $1k in today's money. But for now: wow.
plemli it will likely be cheaper, we are making major leaps and bounds with nano technology like graphene and carbon nano tubes.. getting to the point of making transistors.. in 10 years silicon may be outdated
Have you heard of the nano tin particles that are room temperature super conductor? And they are thinking with fluoride added into the matrix they can get it to be super conducting up to much higher temps
Today I am trying to routing my first bga, with lpddr4 memory that works at 1.2GHz and TH-cam recommended me that video like "ha ha ha" watch what really cool engineers do.

Someone might have asked already, but on 13:08 you mention two "distributed" amplifiers in each arm of the hybrid for the 64 GHz clock. Do you mean "distributed" between the hybrid's arms? I do not see a reason for a broadband amp to amplify a filtered 64 GHz tone.
As I've got, it's just main low freq clock at 8 GHz (low noise PLL clocked by low noise OCXO), and higher clocks are formed just by cascaded doubling. This results, in theory, the ideal timings between cascades, by the definition of harmonics. The main comlicated technical issue is alingment of delays between cascades, due to the finite (and, in this case, actually very low, lol) speed of light. This results to extremely high geometric requirements to machined parts and traces.
Oh, an oscilloscope! I was thinking it was a spectrum analyser but had to re-read the title. Holy poo, that's insane! The rise time must be in femtoseconds or attoseconds.
Keysight has amazing products! They’re also an equally amazing employer🤗. I work for another division over there, so very nice to see a tear down of this caliber on products on the other side of the house. Great vid! New subscriber here; you got me hooked on your tear down of the E4446a spectrum analyzer.
Question on the calibration value measured The scope shows a value of 3.3ps for the fall time. This means the scope is sampling the edge much better than the 256GS/s spec. If it sampled the edge correctly using the 256GS/s speed then the 2 sample values are 3.9ps apart. So how is it able to measure 3.3ps for the fall time for the edge? Am I missing something?
isnt the spec for fall time the time it takes for it to fall from 90% to 10%? so if the signal goes from 95% to like 5% you could probably extrapolate that the fall time is quicker than the sample rate? also you can use multiple aquisitions to cheat your raw sample rate if your sampling timing is precise enough
The thing with these is that I wonder how you can be really sure that what you see is the actual wave form. With low end scopes you can always take a higher end to confirm.
There must be an enormous amount of reagent grade silver in that mechanical attenuator. It is possible that the CMOS ASICs are made by GlobalFoundries as they have worked extensively in the past with Chartered.
Do you know what happen to the data after the dsp? It go to the CPU motherboard and processed by the CPU or the data is overlayed on the screen and the gui is runner's by the CPU?
I am rewatching this video i guess for the 4th time as my company about to buy one :D I was wondering, how did they manage to isolate all 8 lines per ADC in the frontend module. They look like they are laid out very very closely. Any ideas?
I'm interested how the time domain waveform looks like after the samplers. It is new to me that the sample and hold circuit of the ADC is not on the same chip with the quantizers. Does it look like as a series of step functions with different amplitude or impulses with different amplitude? Could you help me out with good article about it?
As I've understood, basic idea of operation is simple: This scope is running all the ADCs at some one low frequency, and, in fact, they are semi-directly digitizing one input. The magic is, that they are sampling with small equal delay (clock phase shift -- more correctly) between each next ADC. This complicated golden S&H circuitry is doing the job of fast and precised sampling with different phases at this one low frequency. Then, output sample stream is formed just by simple placing samples of each ADC one after one. Thus, answer to your question is very simple: Signal after each sampler looks as time-quantized copy ("staircase") of input signal, with sampling frequency equal to full sample rate divided by number of "phases". Why isn't it possible for these signals to look like stream of short pulses? -- Because duration of these pulses might be in zeptosecond range (duration of actual slopes), what, in my opinion, is truly impossible, and not neccesary for operation of each next stage of samplers and ADCs.

New subscriber here; you got me hooked on your tear down of the E4446a spectrum analyzer.
WOOW What an UNBELEVABLE TECH :O
The computer screen I looking this video on is smaller then the screen on this oscilloscope..
Question on the calibration value measured
The scope shows a value of 3.3ps for the fall time. This means the scope is sampling the edge much better than the 256GS/s spec.
If it sampled the edge correctly using the 256GS/s speed then the 2 sample values are 3.9ps apart.
So how is it able to measure 3.3ps for the fall time for the edge?
Am I missing something?
isnt the spec for fall time the time it takes for it to fall from 90% to 10%? so if the signal goes from 95% to like 5% you could probably extrapolate that the fall time is quicker than the sample rate? also you can use multiple aquisitions to cheat your raw sample rate if your sampling timing is precise enough
The thing with these is that I wonder how you can be really sure that what you see is the actual wave form. With low end scopes you can always take a higher end to confirm.
It's not the actual waveform. When getting close to the cutoff, everything looks like a sine wave.
That's the point of the calibrator.
This is INSANE !!! Cant wait for the Chinese clone for $19.95 with free shipping !
Great video. Thank you.
There must be an enormous amount of reagent grade silver in that mechanical attenuator.
It is possible that the CMOS ASICs are made by GlobalFoundries as they have worked extensively in the past with Chartered.
We sometimes work with other ASIC manufacturers, but for some small-batch super-high-tech stuff we use our own fab in Santa Rosa, CA.
Well, this is simply amazing! Is there a reason for the front end to be so messy? Why not make all four channels symmetrical?
38:31 Is that thing made out of solid gold??
I hope they let you keep it 🤓
Any technology sufficiently advanced is indistinguishable from magic!
What's the power consumption of that? Wouldn't be surprised if it tripped a normal 15A/115V breaker the moment you turn on the 2nd channel. :)
Love for the fellow treckie!🙂
Do you know what happen to the data after the dsp? It go to the CPU motherboard and processed by the CPU or the data is overlayed on the screen and the gui is runner's by the CPU?
I am rewatching this video i guess for the 4th time as my company about to buy one :D I was wondering, how did they manage to isolate all 8 lines per ADC in the frontend module. They look like they are laid out very very closely. Any ideas?
25:18 Damn, that board is *THICC*
if I had one of those BNC inputs I'd sell it and get a 200MHz scope with the money!\
Excellent video, sir! Thanks!
😎 OWON salió del planeta..... Impresionante tecnología, y es de minimo 5 años atrás, que se estará cocinando ahora?
I'm interested how the time domain waveform looks like after the samplers. It is new to me that the sample and hold circuit of the ADC is not on the same chip with the quantizers.
Does it look like as a series of step functions with different amplitude or impulses with different amplitude? Could you help me out with good article about it?
As I've understood, basic idea of operation is simple:
This scope is running all the ADCs at some one low frequency, and, in fact, they are semi-directly digitizing one input.
The magic is, that they are sampling with small equal delay (clock phase shift -- more correctly) between each next ADC. This complicated golden S&H circuitry is doing the job of fast and precised sampling with different phases at this one low frequency.
Then, output sample stream is formed just by simple placing samples of each ADC one after one.
Thus, answer to your question is very simple:
Signal after each sampler looks as time-quantized copy ("staircase") of input signal, with sampling frequency equal to full sample rate divided by number of "phases".
Why isn't it possible for these signals to look like stream of short pulses? -- Because duration of these pulses might be in zeptosecond range (duration of actual slopes), what, in my opinion, is truly impossible, and not neccesary for operation of each next stage of samplers and ADCs.
