| 摘 要： | 等效时间采样法(Equivalent-Time Sampling)是一种不同于实时采样(Real-Time Sampling)的信号数字化方法。由于它可等效实现高速采样的数字化效果,所以这种方法在某些特定的场合(如测试仪表)得到了广泛的应用。本文描述了这种采样法的一般原理和特点、讨论了 DZK-1型光时域反射计(OTDR)是怎样用该方法实现高速信号采样的,并给出了该部分的实现框图。

| Abstract: | Equivalent-time sampling is a kind of signal digitization method which is quite different from real-time sampling.Because of its equivalent effect of high speed sampling,it has been widely used in some particular occasions such as instrumentation.This paper describes the principle and characteristics of this method.It discusses how the method is used to implement the high speed sampling of signal in Type DZK-1 OTDR and it also gives the block diagram of the related part of the system. |
