Design and implementation of random current source based on analog output card

摘要

Based on current output function of the programmable analog output card PCI-926, used the random number generator of Matlab statistical toolbox and LabVIEW simple graphical programming function, a new kind of controllable random current source is designed which has many advantages, such as controllable, adjustable, easy to use, etc. The random current provided by random current source is tested by experiment and results show that the random current source to provide the set value of the random and compliance with the same set of probability distribution, so as to provide access to a random current of new ideas.
