13.5 CAN (option R&S MXO5-K520)
CAN is the Controller Area Network, a bus system designed by Bosch for use within
automotive network architecture, for example, for brake, power train and engine man-
agement. Today, it is also used in many other systems, for example, in industrial
machines, aerospace, subsea, merchant marine.
With the R&S MXO 5 you can decode frames from some of the most common CAN
protocols standards:
●
Classical CAN (CAN 2.0): with the standard frame format (11-bit identifier) and the
extended frame format (29-bit identifier).
●
CAN FD: CAN with flexible data rate. It is an extension of the classical CAN proto-
col and allows for increased data rates and payloads. It is backward compatible
with CAN 2.0.
●
CAN XL: an advanced version of the CAN protocol designed to handle higher data
rates and larger payloads compared to classical CAN and CAN FD.
Required options and equipment
For performing CAN decode measurements, you need the following equipment:
●
R&S MXO 5 with 1 available channel. The channel can be:
– Analog channels (C1-C4)
– Logic channels (D0-D15) (requires option R&S MXO5-B1)
●
One probe
●
Option R&S MXO5-K520
