ScopeCorder module monitors CAN FD signals

April 18, 2018 // By Christoph Hammerschmidt
Yokogawa Europe has introduced a new CAN FD monitoring module for its ScopeCorder family of portable data-acquisition and recording instruments. The 720242 plug-in module is compatible with the DL850EV (Vehicle Edition) instrument and the new DL350 ScopeCorder fitted with the /VE option.

Using a ScopeCorder together with bus monitor modules to decode data from automotive serial buses such as CAN enables engineers to display information such as engine temperature, vehicle speed and brake pedal position as trend waveforms and compare this with the analogue data from the actual sensors. This enables automotive engineers to gain a thorough insight into the dynamic behaviour of the complete electromechanical system. 

First announced in 2012, CAN FD (CAN With flexible data rate) is an extension format for CAN in which the transfer rate and data length of the data field has been increased while still following a protocol common to CAN. It enables data rates higher than 1 Mbit/s to be transmitted on a CAN bus and is thus able to deliver the higher bandwidths now required by the automotive industry for in-vehicle networks. Yokogawa already supports CAN FD triggering and decoding in its range of DLM mixed signal oscilloscopes for physical layer bus development.
