It's a pity that only the DHO9xxS can do Bode plot (as far as could tell from the user manuals of the 800, 900 and 1000 series).
I would expect that at least for the 1000 series Bode plot would be available, by synchronising the scope with an external generator, like the Siglent SDS1000X-E (and others) does with the SDG1000X (and others)
