One Oscilloscope. Four Domains. Why Modern Automotive Debugging Is a System Problem

One Oscilloscope. Four Domains. Why Modern Automotive Debugging Is a System Problem

At Embedded World 2026, one Tektronix demo captured why modern automotive debugging spans four domains: CAN bus, RF/wireless, EMI, and signal integrity — all from a single oscilloscope platform.
