The HDO4000 doesn’t have bode plot option, nor sin(x)/x
It's got Sinx/x, but you can't turn it off.
Referring to the user guide this scope doesn’t have sin(x)/x interpolation and the display mode is vector only, to my knowledge it’s the same as in the MSO5000 scopes.
Check section 19.1, page 238 in the user guide.

Have you watched my video?
The zoomed in waveform in not linear vector based, it's sinx/x
I asked Rigol if I could turn off Sinx/x and they said no I can't.
I do know what that manual is showing, but that's not how the scope i have actually works.
Yes, I did, twice before I posted my message.
After when you pointed me to “The zoomed in waveform in not linear vector based, it's sinx/x” I watched the video few times (min 18:05 – 25:00) ... I do agree with you, for sure there is interpolation involved. I was suggested by the user guide and it’s the reason why I pointed the sin(x)/x topic.
Is it possible to switch to dot mode before “stop” and later zoom it and repeat the test?
Dave, thank you very much for sharing your knowledge and experience with the community.
I was not trying to start an argue/war conversation, I’m only trying to understand this topic.
Personally, I don’t care much for sin(x)/ interpolation, sometimes it comes handy. If I analyze anything besides RF, I use dot, or vector mode and I prefer min 20 samples per period.
I truly appreciate your contribution to the EE community.
