PCAN-Diag 2 is a
handheld diagnostics unit with a wide range of functions to allow
investigation of a CAN bus, such as detection of the CAN bit rate, bus
load measurement, and termination measurement. As well as receiving CAN
messages, it can transmit either individual messages or entire sequences
of them. In addition, the internal memory card allows tracing and
playback of the CAN traffic.
The integrated two-channel
oscilloscope enables visualization of CAN signals. Single CAN IDs and
various events can be used as triggers. The CAN frames are decoded from
the analog signal, for example, to detect errors in the frame.
