I just bought my first oscilloscope, a Siglent SDS1202X-E, and have been reading up, watching videos and trying a few experiments to get to know it better.
One thing I was interested in trying would be to put the scope in XY mode, then connect the horizontal and vertical inputs to the left and right channels of stereo audio to see what kind of patterns it produces. I was thinking I might do this by connecting the scope probes (via a 3.5mm plug and dissected cable) to the headphone jack of an iPhone playing music.
This seems as though it ought to be safe, but I thought just to be sure I ought to ask. Is there anything I need to worry about?
