We use almost all Rigols at work. My slow bench scope is a 500 MHz
DS4034 (upgraded from 350 MHz)

https://www.dropbox.com/scl/fo/ns08x686afbayjsw8c2ab/h?rlkey=iu4h89057t755pueg4ijnldbo&dl=0

and my fast scope is a Tek 11802 sampler.

I bought the Siglent as a gift, and I was curious about it.

So is ours! It cost $50K.  It doesn't make much sense and there is
basically no support. It doesn't make sense to them either.
