First picture on EEVblog of the new R&S MXO4 series oscilloscope :)
Sighound36:
Apologies in the main review I forgot to mention two other quality points I missed off the list.
MX04 'extra likes'
Bode plot ability and set up wizard can't fault it spot on, simple intutive and for oursleves with filter characterisation almost essential (Lecroy take note!)
A very small but neat feature of when saving any screen information to usb drive, the MX04 automatically sets up and labels a file named MX04, may not seem a great deal but if in the heat of battle and you need a quick one-shot screen grab of an important event, you will not miss it by having to set up and label a file. Rather than going back a trawling through many files to find it.
Like I mentions simple, but very useful 8)

Just got my MXO4 eval unit !
This thing is huge!!! It makes my Siglent 5104X look like a toy ! The screen is gigantic.
More later !

Sighound36:
I actually found it about average size wise, although that depends on the size of your bench in fairness, it's very close to the HDO6000A size. Let us know how you get on with this quality scope 8)
Shortly I will have another review of some great Rohde & Schwarz equipment the FPL spectrum analyser.

No one has ever asked us to make the screen smaller :)
And there's also an HDMI output, so you can go even bigger ....

My MXO4 Review
------------------------
Disclaimer: I am not a professional reviewer, these are just some
observation from using the MXO4 for 7 days.
Looking through the forum, I feel like Sighound36 did a great job
reviewing the MXO4. I only have had mine for 7 days to play with,
and focused mostly on the usability aspects and user interface.
To learn how to use the MXO4 I pulled out one of my customers
projects, where we had some issues with SPI interface. I wanted
to see if the MXO4 would be better or worse than my SDS5K.
Previously, I had many issues with the SDS5K when I tried to do
large captures. Unfortunately, the MXO4 exhibits very similar issues.
It cannot decode a simple SPI interface. It also has issues
triggering properly. Yes, I had the voltage levels/threshold set
correctly. I can see transitions and manually decode the correct
values, but I was expecting the MXO to do that. I observed the same
failures in both Logic Analyzer mode and analog scope mode.
The zoom feature of the MXO4 is great if you want to examine a part
of signal wave form. Something like under or overshot, for example,
it is great to zoom in. However, if you are trying to zoom in on a
large capture, the zoom function of the MXO4 is horrible and I can't
see myself using that in real life debugging sessions. It is quite
common for me to capture "long" transactions. In these cases when
I want to zoom in to examine a smaller section, the MXO4 zooming
becomes useless. R&S should take a look at how Siglent implemented
zooming and expend their zooming capabilities.
Overall, the User Interface is very slow and buggy. The unit freezes
randomly, and requires a power cycle. Simple adjustments, like
horizontal zoom, can freeze the unit for up to 15 seconds, before
it updates the screen.
The UI & menus take a bit getting used to, that's not necessarily
bad, but I did feel that the menus were confusing at times (specially
trying to set up a trigger for SPI decoding, for example). Compared
to Siglent, I found they grouped the functions and menus more logically.
For me, the MXO4 is just not worth it. My SDS5K that costs 1/4 of
the MXO4, and does everything I need and in many areas much better
than the MXO4. My next scope must have a faster user interface and
excel in decoding various protocols.
