一种微机化穆斯堡尔谱仪波形发生器

A microcomputer-based waveform generator for Mssbauer spectrometers

基于８７５１单片机的穆斯堡尔谱仪波形发生器用１２位Ｄ／Ａ转换器产生高线性度的三角波电压基准信号，并用８位Ｄ／Ａ转换器精确地控制三角波电压基准信号的幅度，同步信号和步进信号可任意延迟，以获取高质量的折叠谱．该波形发生器可通过面板上的ＤＩＰ开关或ＩＢＭ－ＰＣ等微机的串行口实现控制。

A waveform generator for Mossbauer specbometers based on 8751 single chip microcomputer is described. The reference waveform with high linearity is generated with a 12 bit DAC,and itS amplitude is controlled with a 8 bit DAC. Because the channel advance and synchronous signals can be delaied arbityarily,excellent folded spectta can be acquired.This waveform generator can be controlled with DIP switches on faceplate or series interface of the IBM-PC microcomputer.
