For the 1394 bus application with a new generation of aircraft,the wire as the medium of the bus has an influence on the char-acteristic of the bus transmission. To satisfy the 1394 wire requirements for vehicle management system,analyze the structure of 1394 wire and difference impedance,put forward the test equipment and environment,test the 1394 wire used the special equipment and test result is the tested 1394 wire satisfied difference impedance index. With the conclusion,it normalized standard test index. Provide theory proof and test data for high reliability 1394 wire. It lies a foundation for the 1394 wire choice and application,has a guiding significance for building the whole 1394 bus and guide the whole system design.
