Having done a 3+ year stint as a bench tech back in the heyday of CB, I have a lot of respect for Mike and his work. That said, I found it a little odd that he would purchase a function gen. to use as an RF generator
. It certainly shouldn't have the kind of error it does (which Rigol seems to be calling a feature
), but I also wouldn't expect it to be a suitable replacement for an RF generator. There's a reason RF generators are $$$$$$ and function generators are $$. Because of his unrealistic expectations, I feel his harsh criticism is a little unfair to Rigol.
