Trying to display bandwith via Math on Siglent SDS2k+/2kHD/800X HD

In the manual, dx can be selected between 2 and 20.
In real, it starts with 4, higher you can only get when using the keypad - the knob does nothing.
And: When you choose "max" on the keypad, dx has the value 256..
Tomorrow I´ll look at the adjustments the lecory scopes offers on d/dx and FFT.
I expect nearly "nothing", because "somehow" it works as expected without doing anything special.

More exactly I should add "... for timebase >= 50ns/div" to this statement.

At <= 20ns/div the flat spectrum is not plausible either, but this seems to be a different issue.

Hi,

What else can we do to manifest that this is a bug ?
