The Yokogawa DL850EV ScopeCorder (Vehicle Edition) combines digital oscilloscope performance with industrial-grade data logging for automotive and transportation system analysis. It acquires, processes, and records electrical signals, sensor data, and vehicle network traffic simultaneously—eliminating the need for multiple instruments. Engineers use it to correlate dynamic behavior across analog measurements, logic states, and CAN/CAN FD/LIN/SENT bus protocols, delivering actionable insights into electromechanical system interactions.
