I didn't follow that back then, I just know that when I got to know it (2018), it was really good.
You can't compare that with what rigol almost reluctantly pushed after the MSO5000 via firmware update.
And that was years ago and what you can see with the 900S is exactly the same - they have no desire to make something good out of it.

What problem ?
That would be good if you could name it, because I have access to the scope at work.
This is also interesting in that the FFT performance of rigol is the biggest weakness for me, apart from the lack of a bodeplot function.

You people dont look dave's video arent you people? siglent has wobbly fft and dho800/900 can be connected to 99" tv with touch if you wish to :palm: btw.. going to sending 'less small sparrow afg' board to jlcpcb tonight after final checking stage... fwiw..

I don't follow Siglent threads much either but their firmware has release notes and it's
quite long:

I know the Bode plot can glitch if it does one of its little internal recalibrations half way through:

You probably don't remember Siglent mailing little bags of capacitors to people to install in their new 'scopes either?

Imagine if Rigol did that? We'd never hear the last of it.
