Adjusting the timebase (e.g., 10 milliseconds per division) allows you to capture a single event or a stream of multiple events.
To deepen your diagnostics, you can download specialized waveform reference charts to keep on your shop laptop for immediate comparison. To assist you further, please let me know: pdf automotive oscilloscopes waveform analysis
A standard fuel injector waveform provides insight into both the electrical circuit and the mechanical movement of the injector pintle. Adjusting the timebase (e
Look closely at the trailing slope after the spike or during the switch-off phase. A tiny dip or "hump" reveals the physical movement of the injector valve closing. If the hump is missing, the injector is mechanically stuck. Ignition Primary and Secondary Systems Ignition diagnostics require isolating the spark phases. Look closely at the trailing slope after the
AC signals periodically reverse direction, generating sinus waves that alternate above and below a zero-volt reference line.
CAN-H should mirror CAN-L. CAN-H mirrors upward to 3.5V, while CAN-L drops downward to 1.5V.
