| Abstract: | The hardware and software of scanning power supply are described. It provides an automatic and convenient way to measure characteristic parameters of plasma by Langmuir probe,thus,it is a key innovation point that is using software programmed by the graphical language LabVIEW,and it makes use of the computer hardware and software to control instruments. The design of hardware and software is presented in detail. The hardware consist of PCI-6251 acquisition data card,High-voltage power operational amplifier PA93,ISO 100 AP,and NI virtual software LabVIEW. It is more accurate than the manual method,and it can deal with data and get the plasma（ I-V） curve in time. |
