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

@badbruno If you are asking me: The PP15 max output is 1500W. If you need more, they have the PP20. I'm running everything off my PP15 and only at 40% load.

Also: The reason I upgraded is b/c I noticed the system sounded better at different times of the day. 

I just installed a PS Audio Power Plant 15 yesterday and has made a HUGE improvement in my listening enjoyment. I was using a APC H15 power conditioner previously with good results but as soon as I lit up the PP15...bruh. Clarity, detail and dimensionality were significantly improved. Slam dunk purchase for me. PS Audio is selling them a 20% discount r/n on their website.
