Comparing the Rigol DHO1074/DHO1204 vs. MSO5104 display quality

A general improvement over the MSO5104 is the invisibility of the menu. This reduced the useable screen area quite a bit in the past.




While testing the exact same setup I did misconfigure the timebase once, so slew rate in the close-up view are not graphically comparable.
I think the newer 12 Bit oscilloscope gives quite a bit more clarity here.




The DHO1074/DHO1204 clearly tries to draw an anti-aliased line for each sample point in memory. This creates the appearance of „spaghetti“ hanging from the ceiling here, with a lot of level changes. I prefer the display like the MSO5104 does. It shows sth. like: „There is something here, but I lack the resolution to draw it properly.“
If somebody knows if this behaviour can be improved by some setting, please let me know. Until now, this is the only drawpack I found on the DHO.

ACRMS noise (20 MHz)

This was kind of an afterhthought. Original ideas was to compare the „low noise“ of the Rigol to a much more expensive scope like the MXO44. Therefore the MSO5104 results are lacking here, for now.
