Not super common but you can find models which have this feature in all price brackets and from various vendors. I can highly recommend having a scope around which has settable bandwidth filters; I certainly have put these to good use over the years.

Paul, please show us a movie. That would be cool.

Took a brief look in the MXO5 manual (from Martin's link), with a few searches, (its close to 30 pages).. https://www.batronix.com/files/Rohde-&-Schwarz/Oscilloscope/MXO5/MXO-5_specs_en.pdf

--- Quote ---The high definition (HD) mode increases the bit resolution of the waveform signal by using
digital filtering, leading to reduced noise. Because of the digital trigger concept of the
R&S®MXO 5, signals with increased numeric resolution are used as the input for
triggering
1 kHz to 10 MHz 18 bit
100 MHz 16 bit
200 MHz 15 bit
500 MHz 14 bit

Look'ed on Youtube to see if I could muster a video demonstrating it in practice, to see how these bandwidth filters were implemented on high-end R&S scopes, but no dice, nothing pops up.?
The selectable 1Khz to 300Mhz filter seems to be pr channel on the flagship MXO5, which is a plus... would love to see a video with it in practice

Yep, I use the H/L filters all the time on my portable scope,  surprised me' how much I value it, and the ability to continuously see the visual impact on the specific channels im adjusting it on....though my unit goes from 30Khz to 100Mhz - with down to 1Khz steps, which doesn't seem to make much sense, with such fine 1Khz granularity..but obviously another Catfish

Could be something for the (siglent)wish list.

Screenshots from a HDO6034A, I like it when ERES is in the channelsetup box.
This is then not simply "ERES for all", but only for the respective channel - Also something for the wish list.
