In the whole measurement process , the near field data sampling is a very important but the most time - consuming phase 在整个测量过程中,近场数据的采集是最为耗时的一个重要环节。
Now , dsp based high - speed data sampling system has become a basic module in vxi automatic testing system 因此,基于dsp的高速高精度数据采集模块已成为vxi自动测试系统的基本模块之一。
Secondly , a / d conversion circuit is selected in the temperature test of accelerometer for data sampling 其次,在进行加速度计静态温度试验时选取了a / d转换对加速度计输出信号进行采集。
The software part is divided into communication module , self - diagnosis module , data sampling module and data dispose module 软件划分成自检模块、数据采集模块、数据处理模块、通信模块和键盘显示模块。
The data processing system includes a data receiving means for receiving a plurality of input data sampled at a first frequency 此资料处理系统包含一个资料接受装置,用来接受以第一个取样频率所取样出的一组资料。
