Under Preferences, Oscilloscope there is the option "Enable sample rate filters", but I could not find any documentation about it, nor did I notice any effects on sampling.What is it for? How should it work?
Thanks and best regards.

This preference has no effect at maximum sample rate, as there is no filtering/decimation at max sample rate.
Sample rate filters are digital filters in the FPGA that are applied to the acquired signal before decimation at non maximum sample rate. If the preference is disabled, the filters are no longer applied and the signal is simply decimated when working with non maximum sample rate.

Thanks for your answer!
So the filters would reduce aliasing at lower sample rates? What type of filter are they? (IIR 2nd order?)
Any documentation I missed so far?
