A four-channel oscilloscope is a powerful diagnostic tool used in the automotive industry to monitor and analyze electrical signals in real time. The "four-channel" part means it can measure and display four different signals simultaneously, which is especially useful in modern vehicles with complex electrical and electronic systems. Common Uses in Automotive Diagnostics: 1. Engine Performance AnalysisCamshaft and crankshaft sensors: Comparing timing signals to check for proper synchronization. Ignition systems: Monitoring primary and secondary ignition waveforms across multiple cylinders at once. 2. Fuel System DiagnosisInjector signals: Checking voltage and current draw of multiple fuel injectors for firing consistency. Fuel pump operation: Analyzing powe ... read more
