| Abstract: | The whole process of designing virtual X--ray fluorescence analyzer was particularized with LabVIEW which is a new type of graphical programming platform and data acquisition board , based on virtual instrument technology. It can analyze the output of the radiation detecor and give the height spectrum by the method of the continuous real--time data acquisition and the abstraction of pulse signal amplitude. The simple test shows that this system can meet the demand, and it can be easily expanded according to the situation, which shows the flexibility of virtual instruments technology and extends its application in nuclear signal measurement. |
