| Abstract: | To evaluate the reliability level of the transmission performance of gigabit data bus used in aerospace engineering, tests including different temperature conditions and test frequencies are carried out based on the aerospace component assessment technology, to study the performances, such as the attenuation, the differential impedance, the capacitance, and the delay influence. The boundary margin of the performance parameters of the product under different application conditions is obtained. The variation trends of the transmission performance parameters are revealed, which can be used as a data support for the selection of aerospace models. |
| Keywords: | gigabit data bus transmission performance reliability evaluation test |
