An oscilloscope is not just for electrical signals; with pressure transducers, it performs dynamic pressure testing. A , for example, uses a low-amp current clamp to measure starter motor current draw during cranking. As each cylinder fires on its compression stroke, it creates a load on the starter, resulting in a current peak. A low peak indicates a cylinder with mechanical issues, such as leaking valves or piston rings. Similarly, an in-cylinder pressure test directly views the pressure waveform in a cylinder to find valve timing and sealing issues. By following best practices and using the right

Secondary ignition waveform analysis is perhaps the most classic use of an automotive scope. The pattern is divided into three sections: (the high-voltage spike needed to ionize the spark plug gap), intermediate (the spark duration, or "burn line"), and dwell (the coil saturation time). The secondary pattern shows the condition of the entire ignition system, from the coil to the spark plug. A low, long spark line points to low resistance (e.g., a shorted plug lead), while a high, short spark line points to high resistance (e.g., an open plug lead or worn plug). A , for example, uses a low-amp current

The holy grail. A PDF dedicated to this will show you how to overlay a pressure waveform (PSI vs. Degrees) on top of an ignition waveform. You can physically see the moment of combustion and identify detonation (knock) that knock sensors miss.
