CAN bus conformance test system
CAN FD/CAN bus conformance test system.In the hardware system based on TOSUN independent research and development of the bus analysis toolIt is equipped with standard peripheral instruments such as programmable power supply, oscilloscope, digital multimeter, etc. It is equipped with interference meter, conformance test chassis and programmable power supply;Write test scripts in software based on TSMaster to implement the test logic required by the specification.Through the programmed invocation of the hardware system, it can automate the conformance test testing of the physical layer, link layer and application layer (network management, UDS diagnosis, flashing, routing) of CAN FD/CAN nodes for automotive parts and generate test analysis reports in customized formats.

Advantages
-
1One device for conformance testing and network automation testing related content
high degree of integration
-
2Enable automatic testing with a single click, and automatically generate detailed test reports upon completion
high degree of automation
-
3Writing and executing test cases based on TSMaster software makes it easy to expand new test cases, modify test report templates, or add other applications.
scalability
-
4High reusability of scripts, the parameters used for testing are independent of the scripts and configured separately, simplifying the workload of adapting to different projects.
reusability
