If only Edison had won the power war. We would have DC direct from the wall outlet. 😊
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
