摘　　要：数字三维示波器不仅能捕获和显示信号的时间-幅度信息,而且能够以不同的辉度等级或颜色显示事件出现概率。系统采用自适应非均匀综合校正方法实现10 Gsps实时采样;采用实时数字频率补偿方法实现带宽1 GHz模拟通道;采用多体交叉三维映射体系实现500 000 wfms/s波形捕获率。运用这些关键技术研制了工程样机,并给出整机测试结果。实验表明该系统的各项技术指标居于国内领先,为高性能数字三维示波器奠定了技术基础。Digital three-dimensional oscilloscope is a kind of digital storage oscilloscope, which not only can capture and display time-amplitude information of the signal, but also can reflect the probability of event with different brightness levels or color grading. Adaptive non-uniform synthesis calibration method is used to realize real-time 10 Gsps sam- pling. Real-time digital frequency compensation method is used to achieve analog channel with bandwidth of 1 GHz. Three-dimensional mapping technology using multi-body cross system is adopted to achieve 500 000 wfms/s waveform capture rate. Using these key technologies, an engineering prototype was developed and test experiment was carried out. The prototype test results are given. The experimental results show that the technical specifications of the developed prototype of 10 Gsps digital three-dimensional oscilloscope are in the domestic leading position, and the developed technology lays a technical foundation for the development of high performance three-dimensional digital oscilloscope.
