摘要

本文提出了一种时域瞬态脉冲测量中的时间等效采样技术。介绍了荧光光谱的应用，并对不同的采样技术和采样过程进行了简要的研究。该方法利用数字信号处理器(DSP)和个人计算机(PC)来演示该技术。DSP通过标准串口与计算机通信，接收命令和传输数据。除了采样技术外，DSP还通过对采样的数字信号进行平均来抑制噪声。在LabVIEW 6.1的图形化语言G中开发了控制程序，实现了时间分辨脉冲的注册和绘图。利用这种方法，我们能够以16.66ns的时间分辨率和1.25MHz的带宽来解析脉冲

An Approach to the Equivalent-Time Sampling Technique for Pulse Transient Measurements

An approach to the time-equivalent sampling technique in time-domain measurements of transient pulses is presented in this work. An application in fluorescence spectroscopy is mention and the sampling processes as well as the different sampling techniques are briefly studied. The approach makes use a Digital Signal Processor (DSP) and a Personal Computer (PC) to demonstrate the technique. The DSP communicates with the computer via a standard serial port to receive commands and to transmit data. In addition to the sampling technique, the DSP also applies a method of noise suppression by averaging the sampled digital signal. A control program was developed in the graphical language G of LabVIEW 6.1 to register and plot the time-resolved pulse. Whit this approach we are able to resolve pulses with a time resolution of 16.66ns and a bandwidth of 1.25MHz
