摘要

A simple digital measuremeht system of 2-detector Doppler broadening is presented. We use a data acquisition (DAQ) card to digitalize the pulse from main amplifier, and use software to process the digitalized pulse. We demonstrate that DAQ card with software can replace some conventional analog electronic instruments, such as gate generator, delay and coincidence system. The two-dimensional correlation spectrum shows that this system is as good as a conventional analog measurement system. The system is more convenient and more reliable because of using little analog hardware.
