中文摘要：

指令变换器是测试飞行器工作参数和各路信号的关键设备，故设计一种新型的测试指令变换器工作的系统。该系统采用FPGA为主控制芯片，设计了4个模块，其中综合模块解析转发命令与数据，与其他3个模块配合接收和输出测试所需信号，包括48路电压可调的直流量模拟信号，8路时统信号以及PCM数据。试验结果表明，该系统可靠性高，性能稳定。

英文摘要：

The instruction converter is a key device to test the working parameters and each signal of the aircraft,so a new test system for the instruction converter was designed. The FPGA is taken as the main control chip of the system. Four modules in the system were designed. The synthesis module is used to analyze and transmit the instructions and data,and cooperated with other three modules to receive and export the signals needed in the test,which includes 48 DC analog signals with adjustable voltage,8 timing signals and PCM data. The experimental results show that the system has high reliability and stable performance.
