I figured mine out within 10 minutes without a tutorial or manual. Just go through the variables on the side of the screen and adjust them until you see the sine wave.

So I used the oscope on my friends system and it shows a perfect wave like it should. So I am guessing it could possibly be the amp or maybe a bad ground.
