Precise disturbance generator for CAN (FD) networks

Precise disturbance generator for CAN (FD) networks

The compact device can also be used as a network interface for CANoe, giving a combination of disturbance functionality and interface helps to develop test setups for conformance testing with ease.

VH6501 hardware lets developers produce a wide variety of digital and analogue disturbances precisely and reproducibly to automatically test the error handling of ECUs. It can be used as a normal interface for CANoe, or the fault functionality can be controlled via CAPL (Communication Access Programming Language) integrated in CANoe. Due to this tight CANoe connection, test setups with residual bus simulation can be set up easily without additional hardware.

The CAPL API allows users to configure short circuits in the CAN signal lines, interchanging cables, and modifying R/C network parameters for analogue interference. For digital disturbances, almost any digital interference sequences and extensive triggering conditions can be defined. The VH6501 can, therefore, be used to check the controller behaviour during a bus-off or measuring the sampling time.
