Hello,
I am trying to find a decent way to measure line noise from switched mode DC power supplies. For example from a laptop power supply or a USB Phone charger, without breaking the bank. I wanted to ask if you guys had any suggestions for a low cost setup as I was not sure if a Oscilloscope is the only way, and if it is I wanted to determine what specs I would need on the scope so I could find the lowest cost model that could do the job for me.
Any suggestions and help appreciated.
Thank you!
