InfiniiVision 4000 and 3000T X-Series support ISO CAN FD (controller area network with flexible data rate) decoding and triggering capabilities to help debug ISO 11898-1 standard CAN FD as well as non-ISO CAN FD protocol. Waveform and decode update rates increase probability of capturing random and infrequent errors. Oscilloscopes also provide CAN FD error triggering and analysis, including ability to decode, totalize, and trigger on specific errors (optionally filtered by frame ID).
