Compare These Scopes Side-by-SideWhat to Look For
4 channels minimum
Modern vehicles have multiple ECUs and sensors. Four channels let you compare crankshaft position, injector timing, and oxygen sensor signals simultaneously.
CAN bus decode capability
Every modern car uses CAN bus. Built-in serial decode (CAN, LIN, UDS) turns raw signals into readable frames, saving hours of analysis time.
High common-mode rejection
Automotive electrical environments are noisy. Look for scopes with good isolation and differential probe support to reject battery and alternator noise.
