Anything new about this scope? I was waiting for one or the other of our favourite youtubers to get a unit to show it off, but up to now there is no stuff on youtube (except for the offical Keysight video).

This video you may not have seen.

https://www.dropbox.com/s/y55zv11mlson23d/MXR-Series%20vs.%20S-Series%20Demo%20Video.mp4?dl=0

I have to avoid this thread - its definitely not good for my health (I already have an addiction for the 'cheap' stuff) - but this puppy is in a league of its own  :popcorn:

Be careful Sighound - you might not ever return to the 'normal’ world  :P

EDIT: One way out is to become a Keysight product specialist - hopefully you will get this puppy to take home and show to potential 'addicts'  :P

Sighound is hybrid. He can take both the blue pill and the red one and still get back to our world!   ^-^

That video is amazing stuff at (almost) our fingertips!

Thanks for sharing the video, as that is what I have been looking for.  It is a scope truly worthy of the Keysight name and a great upgrade to the existing line.

Well chaps the are two of us here that will be having a home  demo of this puppy next month
However I yet to be convinced until I give the scope a workout if I it passes muster I will takeb one for the home lab

I have identified a few items that could be an issue though the ENOB of 9 bits is a bit of selective specification which is already over twice the noise of the Wavepro with the same parameters.

Where I can see this scope really making an impact is with the RTA bandwidth of upto 320Mhz the cost option here is £9k you can extend this upto the max bandwidth even if the scope is only 500Mhz you pay for a for a frequency extender that is a other 2K strictly not a real true RTA (dds) but no other scope has this feature

The amount of hardware acceleration in this unit is impressive everything except channel upgrades are software upgradeable que the code heads on here  8)

Starting price is £18,800 for the 1/2 Ghz and £21k for the 1Ghz so pricing is very keen in this sector this is will sell no doubt

Will be giving a good work out and a comparison or two however it looks decent.

Well, a 1 Tbps crunching machine should also add a nice power bill... or is it green?   :D

Pisch  :-DD, nothing compared to a famous pair of audio power amplifiers domestic models that idled at 3.2Kw in full class 'a' EACH as they are mono-blocks and they are not even from the land of excess, but  Scandinavian  :wtf:

Personally my lab is plenty warm enough in the summer thank you  :-DD

Joking aside it is a feat of electronic engineering hats off to the Danny Boganoff employers  :-+

I started to revise the scopes chart so the charactristics of acquisition compartment will be easier to understand.

Hoping the differences on Infiniium S-Series and MXR become clearer.

I hope Shahriar gets to show us one. His videos are always great.

One can hope, but every time I've quoted out a trade-in in this tier, at both my day job at big co and my personal lab, the trade-in credit wound up being about what I would expect to get on ebay. I suspect that to some degree they really do just turn around and pawn the trade-ins:

yes, keysight runs an ebay store. i buy all my stuff there.

There a couple of us on EEV blog here who are due one of these units in the very near future pretty sure you will be kept up to date.

I am looking forward to both of your findings and reviews. 

And thank you for putting it next to the S-Series for a size and screen brightness comparison.  I hope the full HD screen makes a big difference in fine details as I had been bugging Daniel for a world class display on the scope without having to attach an external display.

It would jack the price up even more, but a HiDPI ("retina" in apple speak) display on a scope would be the bee's knees.

please let it be not just the FFT function for an hour ;D scopes nowadays have so many functions for an embedded engineer, protocol decoding, power analysis, compliance testing, advanced triggers, no need to turn a scope into a poor SA

(wonder if other forum members share my sentiment, how often do you use FFT on the scope?)

FFT go brrrrr





Seriously though, it depends 100% on your application. If you're debugging hopping PLLS or using the scope like a wideband signal-analyzer, you're going to spend a lot of time with FFTs. If you're tracing SPI busses and switching supplies, probably not.

I look forward to Shahriar's review, especially with that preselector-hacked-into-a-postselector he put together for ADC stress-testing, but I certainly wouldn't mind seeing people with differently flavored applications give it a spin.

Hence why I was wondering what most people use their scope for and if it is FFT function :)

If you're debugging hopping PLLS or using the scope like a wideband signal-analyzer, you're going to spend a lot of time with FFTs.

Wouldn't you be better off with proper RF gear for such tasks, like SA/RTSA? (disclaimer: RF noob here)

If you're tracing SPI busses and switching supplies, probably not.

Well these particular things rarely require > 1 GHz scopes, but there are other things that embedded developers have to tackle more and more often like modern high speed serial buses. For example in my field it would be something like debugging MIPI CSI link, which involves both signal analysis (eye diagram etc) and protocol decoding, maybe compliance testing and one would probably also have I2C decoder on other channels, showing the control commands to the sensor. This kind of stuff.

Yeah, but oscilloscope bandwidth is wider, cheaper, you get four channels (8 on the MXR!), and you can time-correlate with baseband signals.  Even on the fancy R&S signal analyzers, if you need GHz of real time bandwidth, the supported solution is to use the signal analyzer as a preselector + downconverter and then use one of their scopes for the final acquisition/analysis.

The big specification where oscilloscopes still don't compete with spectrum analyzers is spurious performance. That's why Shahriar is so interested in evaluating oscilloscopes on that front: he's answering the question "what can you get away with on an oscilloscope?"

Yep, I didn't mean to belittle other applications. Substitute in MIPI, USB, or PCIe as appropriate :)
