I do remember i've seen a topic discussing about how to locate the two frequency in the two-tone method for IIP3 testing. but i cannot find it now, anybody can help explain it again? e.g. choose f1=flo-100M, f2=flo-195M, and the IM3 tone 8M after the mixer. i really want to know why and how we choose the frequency apart of the two tone.
