阶跃响应特性、频率响应特性及有效位数是数字存储示波器(DSO)性能的重要计量指标。本文提供的HITDSO软件包,直接根据DSO采集的数据,利用FFT的高效算法,得到DSO的上述几项性能指标,并进行图形及数值显示。
Step response, frequency response, and significant digits are important metrics for the performance of digital storage oscilloscopes (DSOs). The HITDSO software package provided in this paper, based on the data collected by the DSO, uses the efficient algorithm of the FFT to obtain the above performance indexes of the DSO, and displays the figures and numerical values.
