How do you attach an Oscilliscope to check ignition system

I have a slight miss that I believe is ignition related. I was looking at the MB manual for 103 engine under "Electrical system, engine" and it shows different images for graphs that represent Voltage versus time. By analyzing the image/signal, a problem can be identified or narrowed down to certain things. I do have access to a 4 channel oscilliscope and would like to know what things do I need (like current probe, ..and so on) and where to hook things up in the engine. Any help would be appreciated. I would like to test the car this coming weekend?
