So it is easier to analyze that data traffic that was on the bus before the error occurred. The software can be adjusted in a way, that a simultaneously running Receive in the protocol monitor is stopped in case of an error. Edge steepness (worst rising and falling edge of a message)Īdditionally, to this logical and physical measurements, the CAN-Bus Tester 2 is continuously determining bus traffic load, bus status and the optional CAN supply voltage.Disturbance-free voltage range (minimum noise-free differential voltage).So you show when your threshold was overruled or if an error frame has occurred. In continuous mode, the error is marked in a timing diagram. In the single measurement mode, it stops and the faulty message is showed in the oscilloscope view. If it overruns the threshold the error will be registered. This measurement runs continuously and compares with given thresholds. By starting a continuous measurement you will also see the min/max of quality level and the variation of the disturbance-free voltage range. Quality level, edge steepness and disturbance-free voltage range are the three showed measurands. The measurement “one station’s view” shows the single values of one node and shows a physical and logical decoded oscillogram. You can easily compare to a saved measurement. At continuous mode, you will additionally see the min/max values. The bar diagram makes it easy to compare. With the measurement “all stations view” you get an overview of the quality levels of the signals. Name the nodes if you want for a better overview. All messages on the bus are now received and analyzed, the nodes with their ID are listed. You should see a green led on your display, showing that there is data traffic.įirst, start the baud rate scan, then scan for nodes. Connect the CAN-Bus Tester 2 to your bus line.
