Dear BigSicilian:
--Please feel free to post any questions you may have on this forum. More than likely you will find someone who can help you. The person who responded to you in such a rude and hostile manner is indeed a member of the forum, but other that that he has no special standing.
--Fudd is know to bear grudges, and when he gets weally weally angwee he posts his screeds in extremely large fonts. He has even managed to get some of his comments deleted, an achievement on this forum. If you hang around long enough you will get acquainted with the other two Sensei of the TrollHouse Dojo; Frick and Frack. Pay none of them any mind.
--In any case welcome to the EEVBlog. I cannot answer your question, but I am pretty sure that someone else can. Dave has done a video or two on it and, as Fudd indicated there are numerous posts on the Rigol DS1052E, though why he would expect someone making his first post to know this is beyond me.
--I for one would be glad to hear anything you or anyone else (make that nearly anyone else) has to say about one of the most popular scopes in the world.
