Forgive my ignorance please. I am looking for an upgrade to my HP 54501A Oscilloscope. I heard that Dave (and others) recommend Rigol. So I was looking at the DS1104E. However I also see Z, C, CA and other types throughout the different models as well.
What do these letter designations represent? I heard Dave say at whatever show he was at that the -S designation means it has a signal (analyzer/generator?).
Anyway, any help would be greatly appreciated. I'm looking to hopefully get as much machine as I can for around $1,000-$1,500 US. Hopefully eliminate as many other machine (function generator, etc) purchases as possible at the same time. Not sure what's possible though. Used is also okay if you know some good places for that (so long as it's not hammered).
Thanks & cheers!
