Aimed at test for the working status of aircraft accurately,a telemetry system was designed,which can provide various types of instruction signals. The logic control was completed by FPGA,and through Ethernet to communicate with the host computer, the speed of it can be 40 Mbit/s. On the basis of communication protocol combining with peripheral hardware,test parameters are provided for aircraft. The experimental results proved that the range of charged instruction signals produced by this system is stable,and the respond of non-charged instruc-tions is accurate. This system has the advantages of reliability and interchangeability,which occupies a powerful practicality.
