Those are minor technical details. You are missing the main point of the current paradigm: making more stuff is not a goal. The goal is making everybody happy. VLV

I think it's more like Rigol sells houses, and you bought a two-bedroom house (although you're aware they also sell three-bedroom houses)... and one day you notice (or Dave Jones metnions that) there's another door in your home. There's no lock on that door, no sign on it saying, "keep out!," etc. Your ne'er-do-well liberal democrat son moves back home after flunking out of his liberal studies program at the local college and you get to thinking... having that kid spend his nights in his own room rather than sleeping on the couch in the living room every night would be nice... I wonder what's behind that door? :-)

But why didn't they do the 50 and even 20 MHz bandwidth limits digitally? They have 1G samples/second to work with. There are some saturation issues that might be best handled with analog limiting, but this *is* a cheap scope. John
