WOOW What an UNBELEVABLE TECH :O

Shahriar, It's great to see such an in-depth teardown of the tool. How long did they let you "play" with it? Do you have the contacts with Keysight through work such that they lend you such equipment?

That's absolutely crazy. I really have no idea how they measured those parts during the development.

Very impressive piece of hardware. Thanks for the concise and accurate information.

Wow, speechless!

These are number i never expected to see in my lifetime and i have not even seen the video yet :P

Normally I would not think of a scope as a phase noise measurement system, but with the jitter analysis package I am thinking this could measure close in SSB phase noise on mmWave sources. Any thoughts on this?

Excellent

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 :)

still shocked and awestruck! mind blowing indeed. Are those signal lines in the acq board SIW or guarded striplines? Although the dispersion of SIW might be unacceptable here... Also, does it go down to DC or is there a minimum frequency input?

Well, this is simply amazing! Is there a reason for the front end to be so messy? Why not make all four channels symmetrical?

OMG! Amazing!

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.

Can you show what that extra chip to the left of the daq board is? Can you also lift the heat sink of the hbm module to see which part they used?(hbm1 or hbm2)

At this level of price and function, I'd be very afraid to hook anything up to it! but it would look soooo good on my bench!

Looks like I gotta hold out for the handheld version for use in the field.

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?

@17lvlham

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.

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. =)

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
