We can talk endlessly about the distinctions between hobbyist budgets and professional budgets, but the reality is that I see fewer scopes in the Keysight/R&S/Tek class every day in all walks of life. Companies who would previously have purchased only the classic premium brands now have benches full of Siglent and Rigol hardware. They are showing up in demo/webinar videos from major players.
Honestly I'm not sure I understand the role for a $20K-$50K oscilloscope, especially if Keysight is going to continue to be stingy with acquisition memory at that level of play. There are markets for $100K-$1M scopes and there are markets for $1K-$5K scopes, but who is going to spend $30K at Keysight when they could get the same thing for $10K out of China?
It was one thing when the Chinese scopes sucked, but then so did Japanese cars, at one time.
