I definitely recognize that lurkers like me are an impossibly small market. I can't even get Keysight to directly sell me used equipment with only 90 day warranties just sitting in inventory for instance (edit: one of the big reasons for waiting for the MXO 5). I can definitely appreciate that you can't expect to make money and cater to such small numbers, and honestly when I originally posted I never expected anyone from R&S to actually see it let alone respond to it. I appreciate your taking the time to respond here. I really hope this launch goes well for R&S. I look forward to seeing where you guys go with these products.

Well, we spent over 4 years developing our own ASIC for the MXO4, which now has the fastest waveform update rate in the world (plus the deepest standard memory, our patented digital trigger, etc. etc. etc.). 

Since the cat is already halfway out of the bag (and will be all the way out of the bag in about 8 more hours), the MXO5 leverages a lot of those years of R&D we put into the MXO4.  And work on the MXO5 began long before the MXO4 was released last year.

Since the cat is out of the bag, can you elaborate on the MXO5 ASIC?  You make the comment of spending 4 years to build your own for the MXO4 and starting this one well before that.

The MXO5 datasheet says it's 2.5GS/s and 12-bit ADC and 18-bit architecture in HD mode. Is this a R&S custom made ASIC/ADC chipset as well? and how does 18-bit storage work?

Thanks!!!  And there are quite a few R&S folks -- including some of our oscilloscope design team members -- who are here on the EEVblog forum as well:  I'm just one of the few who posts as an R&S employee using my real name :)

And please feel free to reach out any time.  We honestly do appreciate all of the feedback and comments we get!

We actually started the brainstorming for the MXO4 back in 2016 (!!!) and started active development in 2018. 

And yes, the ASIC in the MXO is our custom-designed MXO-EP (200 Gbit/s).  Among other things, this ASIC enables an update rate of up to 4.5 million acquisitions/s, which is the world's fastest update rate, as tested by Dave Jones himself.  Dave also did a teardown video if you're interested:

The MXO can use something called high-definition mode where bandwidth is traded off for bits of vertical resolution (lower BW -> more bits).  I actually made a video that provides a brief technical introduction HD mode and how it increases vertical resolution (compared to other methods). 



Not sure how much more I can say before the official launch (4 hours from now) :)

It has something of the Apple events where they present the latest iPhone to their fans.
Wow, you can also use it to make phone calls...Awesome, what's next...? ;)
It´s just another scope at the end.
