Difference is that "the other" scope actually does work as 4ch 200MHz BW scope.
At all times, no special conditions..
Exactly. My comparison was fair, and compared them as 4 channel scopes with what their sampling rates actually allow.
The argument that it's not that hard to disable 3 of the channels on the Rigol to get higher bandwidth is comical, not professional.
one would expect the Siglent to cost ~10X......yes it's that good!! Heck one would expect the Rigol to cost ~3X also!!!
I think that's a great comparison. Both scopes are great at what they do, and cost about the same, but the Siglent is worth 10x what it costs, and the Rigol only 3x what it costs. It's a great value either way, but one is clearly superior...if you want to use it as a tool to do work. If you want to hack and tinker with a the scope as a toy, then YMMV.
