How can I measure the noise on my AC mains with a 2ch oscilloscope?


I’m not an EE so although I have some nice test equipment I need help. Here is the problem, the AC Mains are 120 vac but I’m trying to measure the noise on the AC signal , millivolts. I’d like to answer two questions how bad is my power and second  does my isolation transformer make a difference.

 

thanks for the help

"Live Music" is full of phase anomalies, microphone differences, crowd murmurs and smells, bow rosin dust, insane sound technicians, a lack of sound technicians, balding head reflections, unseasoned wood flooring, drapery...all of which you can try to measure or simply sit there and listen to it. What a mess...
