First picture on EEVblog of the new R&S MXO4 series oscilloscope :)

EEVblog:
The MXO4 locked up on me again while shooting a clip on the digital logic analyser.
Similar lockup result to last time.
The bug last time was that I operated the buad rate decode control too quickly. We'll see what it was this time.

This is why RMS noise is used for comparison.

Shouldn't it be standard deviation to eliminate any DC offset?

Weird that all the menus and stuff keep working. They need to add a watchdog to the acquisition engine/FPGA.

goaty:
Software is not easy to design. I think a lot of 'traditional' companies did and do struggle with good software design.
I remember the remote control of a Canton speaker for TV which was ridculous as well as the 'Rademacher' remote control system for blinds.
In the end, R&S is also probably has not the 'Google'-level of software development...

Yes, also called AC RMS.
