For the situation that programmable fuze high frequency encoding signal have no valid test instrument under simulated environment,a high-speed coding signal test instrument based on high-speed data acquisition and storage technology was proposed.It had high-speed AD converters and FPGA as the core,by effective sig-nal attenuation and differencing according to the characteristics of the encoding signal,enhanced anti-j amming capability and reduced the measurement error.It was designed through a parallel two-channel time alternate sampling technology to achieve a high sampling frequency of 200 MHz.A high-speed timing control logic and data cache partitions in FPGA was used to avoid lost points in high speed transmission.Experimental results showed that it could meet the requirements of high-frequency fuze coding signal test,recording signal waveform was accomplished.The experimental results were accurate and reliable,which could be used as an effective in-strument for programmable fuze high frequency coding signal testing.%针对模拟环境下可编程引信高频编码信号无有效测试装置的问题，提出了基于高速数据采集和存储技术的高速编码信号测试仪。该测试仪以高速 AD转换器与 FPGA为核心，根据编码信号的特点对其进行有效的衰减和差分化，增强了测试仪的抗干扰能力减小了测试误差，采用并行双通道时间交替采样技术实现了200 MHz的高采样频率，使用 FPGA实现高速控制时序逻辑和数据分区缓存，避免了高速存储中可能产生的丢点情况。实验结果表明，高速编码信号测试仪具有完整的记录信号波形，能满足高频引信编码信号测试要求，可作为可编程引信高频编码信号测试的有效装置。
