@Fungus:
The problem with the bodeplot also needs to be fixed, as well as the incorrect (at least one) window coefficients in the FFT. A constant RBW unit designation would also be nice in this context, as well as possibly a display of the current memory points.
More complex features such as a peak or average function for the FFT will probably not come, as these two functions are not even available on the DS70000.
In my MSO5000 days, I had almost weekly contact with rigol support, with a lively exchange about bugs and feature suggestions, including the Bodeplot, which later became available.
Later, however, there were also answers like “we have to launch the MSO8000 first, then we'll probably continue”.
That was between 2018 and 2020, when I had my DHO800 and wrote to support twice, I never received a reply.
In the meantime, I think the chances of rigol taking “proper” care of the DHO800/900 series again are 30:70.
I rather fear that improvements will only come with a new series.
That would be very unwise of them, because it would destroy trust.
