Car Area Network (CAN) bus is great source of data easily collected into vehicles, jet engines and power generation machineries. This Network provides real-time parameters that can be used to correlate measurements and/or evaluate their influence. As an example, the correlation of noise and vibration with the engine load is a typical application of CAN parameter acquisition. For this application, the engine load is collected from the ECU through the CANBus. | Car Area Network (CAN) bus is great source of data easily collected into vehicles, jet engines and power generation machineries.

The hardware consists of an interface box which is adapted to the CAN-Bus impedance and a High speed serial cable (1 and 3 meters) connected to the new analyzer<nowiki>’</nowiki>s high speed serial port. When connected to a CAN-bus the parameter encoding has to be setup in the software allowing their collection by the hardware. | The hardware consists of an interface box which is adapted to the CAN-Bus impedance and a High speed serial cable (1 and 3 meters) connected to the new analyzer<nowiki>’</nowiki>s high speed serial port.

Up to 24 CAN parameters are available. Note that as the maximum recorded channels is 38, it is not possible to records all standards inputs (32 inputs <nowiki>+</nowiki> 4 aux. <nowiki>+</nowiki> 2 triggers) plus all CAN inputs (24 CAN parameters). | Up to 24 CAN parameters are available.

These sub-module contains all the settings related to the parametrics CAN inputs such as data type, parameters and sensitivity read from CAN interface. The CAN interface handle up to 24 different parameters. | These sub-module contains all the settings related to the parametrics CAN inputs such as data type, parameters and sensitivity read from CAN interface.
