He starts off by drawing an image using a single line, saving it as an SVG file. This image is converted into an audio file by Rabiscoscopio, which can then be fed directly into his oscilloscope ...

In this case, those with a nominal value of 300 millivolts (mV) peak-to-peak. This desired measurement can be accomplished using the oscilloscope’s Pass/Fail testing capability to qualify the signal.
