CAN FD capture & decode on Tek's mixed domain oscilloscopes

October 19, 2016 // By Graham Prophet
CAN FD (Controller Area Network with Flexible Data Rate) support enables decoding, triggering and searching on CAN FD bus data on Tektronix' MDO3000 and MDO4000C Series of mixed domain oscilloscopes. Car manufacturers, Tek notes, are increasingly adopting the CAN FD protocol to transmit more data inside vehicles.

The original CAN specification defined in the ISO 11898 standard limited communication speeds to 1 Mb/sec. CAN FD solves the bandwidth limitation problem by allowing faster bit rates and increases payload size from 8 Bytes to 64 Bytes. With the faster speeds and increased complexity come new test and measurement challenges. The new Tektronix CAN FD solution gives automotive engineers working with this protocol a powerful debugging and validation tool to quickly and efficiently validate and troubleshoot designs with full visibility into actual bus traffic.


CAN FD (MDO3AUTO, DPO4AUTO, DPO4AUTOMAX) software is a complete protocol trigger; software capabilities include:


Flexible trigger on data packets and arbitration conditions (I.e. SOF, ID, etc.) with ISO and non-ISO support

Protocol decoding with colour coding of data along with data views

Support for both CAN and CAN FD (ISO and non ISO)

Search support for specific CAN FD data

Ability to store and export data


The MDO3000 is a 6-in-1 integrated oscilloscope with an integrated spectrum analyzer, arbitrary function generator, logic analyzer, protocol analyzer, and digital voltmeter/counter. The MDO3000 is completely customizable and fully upgradeable as needs change. The MDO4000C also offers 6-in-1 versatility and upgrade flexibility together with higher performance and powerful triggering, search and analysis tools.


The new CAN FD protocol test solution for use with Tektronix mixed domain oscilloscopes is included with the MDO3AUTO, DPO4AUTO and DPO4AUTOMAX modules which also include CAN, LIN and Flexray (DPO4AUTOMAX) support. Pricing starts at $1,100.
