TTE node synchronization and communication function test device and test method

The invention belongs to the technical field of avionics, and discloses a TTE node synchronization and communication function testing device and method, and the device comprises TTE super nodes, a super node control host, and a to-be-tested node master controller. The super node control host is connected to the TTE super node through an internal bus, the TTE super node is provided with a plurality of ports and is connected to a node to be tested, the node master controller to be tested is connected to the node to be tested through the internal bus, and the node to be tested supports an AS6802 protocol, has a synchronization role of SM or SC, and supports any combination of time triggering, rate limitation and maximum effort application; the to-be-tested node master controller is of an embedded architecture, is controlled by the super node control host, has the advantages of low cost and convenience, and solves the problem that a traditional TTE node test environment and a test process are complex. 本发明属于航空电子技术
