In this episode Shahriar takes a look at one of the most advanced electrical test and measurement instruments ever created. The Keysight UXR-Series Real-Time Oscilloscope brings 110GHz of analog bandwidth and 256GS/s real-time sampling at 4-channels simultaneously. To make it even more impressive, the entire data-conversion architecture is in 10-bits. This implies that the instruments captures, processes, stores and displays over 10Tb/s of information.
Various architectures of state-of-the art oscilloscopes from Keysight, LeCroy and Tektronix are examined and compared against the new real-time architecture of the UXR-Series oscilloscope. The teardown of the front-end 110GHz module along with the data acquisition board is presented and analyzed in detail. The instrument showcases a wide range of Keysight technologies implemented in various technologies such as InP, SiGe BiCMOS, 65nm CMOS and 28nm CMOS nodes. In combination with Hyper-Cube memory module, data can be captured at 256GS/S from all 4-channels at the same time. Several variants of the UXR-Series oscilloscope will be available from 13GHz to 110GHz bandwidths.
A new calibration probe is also introduced based on the Keysight InP process capable of producing signal edges with sub-3.5ps of rise/fall times with NIST traceable calibration data. This enables users to perform NIST alignment and bandwidth calibration on site without needing to send the instrument back to Keysight.
Several measurements with the scope demonstrates its extraordinarily low noise floor, jitter as well as the capability of the new probe module for instrument calibration. The 110GHz 4-channel variant of the UXR-Series oscilloscope has an MSRP of $1.3 Million US dollars.

*A minor correction to the video: The maximum hardware sensitivity using the InP input preamplifier is 7.5mV/Div at 256GS/s and using the SiGe input is 4mV/Div for the 128GS/s models. The remaining displayed vertical levels are DSP processed. The noise measurement is of course still correct and valid as are the shown ENOB and linearity numbers.*

[@leyasep5919]

Philip Rowney : nope :-) 1 GHz = 1ns (1 "foot", if you assume typical propagation speed) 256 GHz = 1ns/256 = 4fs. That's about one millimeter. (I'm ASD as well, but since I'm french, it's more like QSD hahahah) [sorry for the keyboard layout pun]

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]

En que aplicaciones usas estos instrumentos con especificaciones tan especiales?

[@francescomartina856]

@@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.

[@zullottrocker]

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.

[@amirb715]
