Could there be another explanation for the 90% contrary opinion? At the least, your point is a deep philosophical one, I think. I responded to your statement: Specifically I want to point out that the noise you see is NOT harmonics. It IS; the fact that with some settings of the SA you can't see the individual lines spaced at 50 or 60 Hz is another matter. -- OOO - Own Opinions Only.
