摘要

三维映射技术的应用提高了数字存储示波器(DSO)的波形捕获率,但不能消除DSO的死区时间。本文提出了一种新的三维成像方法——碎片化和集中映射。它将高速大容量动态存储器(DDR3 SDRAM)根据时间基础划分为几个区域。在每个区域存储具有相同触发条件的波形,并对波形进行三维映射技术的后处理。基于双端口RAM的快速波形映射技术和并行波形映射技术大大减少了映射时间。这种方法保证了高波形捕获率和更大的数据存储容量。它还可以实现每个存储波形持续时间的无缝采集。通过数学建模,证明了该系统可以在较短的时间内捕捉到零星的瞬态事件。通过双脉冲测试方法,可测得该系统的最高捕获速率为6250000 wfms/s。经过分析,得到死区时间比降低到43.86%。

A three-dimensional mapping method based on fragmentation
The application of three-dimensional mapping technology has improved the waveform capture rate of digital storage oscilloscopes(DSO), however it does not eliminate the dead time of DSO. In this research, a new 3D-imaging method, fragmentation and centralized mapping, is proposed. It divides high-speed large capacity dynamic memory(DDR3 SDRAM) into several regions based on the time-base. In each region, the waveforms with the same triggering condition are stored, and the waveforms will be post-processed with three-dimensional mapping Technology. Dual-port RAM based fast waveform mapping technology and parallel waveform mapping technology decrease the mapping time greatly. This method guarantees high waveform capture rate and enable larger data storage capacity. It also enables seamless acquisition for the duration of each stored waveform. By mathematical modeling, it can be proven that our system can capture the sporadic transient event in shorter time. Through double pulse test method, it can be demonstrated that the highest capture rate of the system is measured to be 6 250 000 wfms/s. After analysis, it is obtained that the ratio of dead time is reduced to 43.86%.
