TH7012 - CAN FD/LIN Bus Disturbance interface

The TH7012 can be used for CAN (FD)/LIN protocol testing to detect whether a node complies with the communication protocol specification and to ensure the normal and safe operation of the CAN (FD)/LIN network. In addition, the TH7012 can also be used to test whether the CAN IP core of the DUT complies with the ISO-11898-1 CAN communication protocol specification.
