The Yokogawa DL7200 CAN Bus Signal Analyzer is a specialized instrument for capturing, analyzing, and debugging Controller Area Network (CAN) bus signals in automotive and industrial applications. With the optional /F7 CAN analysis function, it delivers frame-level protocol decoding alongside waveform capture—a capability that extends beyond traditional protocol analyzers. The instrument supports CAN Version 2.0B at bit rates from 33.3 Kbps to 1 Mbps, with configurable triggers on Start-of-Frame, message ID, RTR, data fields, and error frames. Engineers can synchronize CAN measurements with analog sensor and control signals, enabling comprehensive system-level debugging.
