From what I"ve read, Siglent, not Rigol.
There's an Aussie yt-channel who does basic-electronics reviews, he's done a couple vids on Fnirsi products ( whining about the name, of course ), so that may help you find the channel..
He, & others, have found problems with the Rigol stuff, re accuracy, iirc.
PLEASE CHECK THAT: MY MEMORY ISN'T PERFECT!
I'm certain that the recommendations I've seen are Siglent NOT Rigol or Hantek
( because I've looked into this stuff repeatedly ),
but I'm NOT certain which sources were doing the recommendations.
& the Siglent digital-input ( for logic ) is a costly add-on, but on SOME models it's possible.
