Development of Altimeter Testing System Software Based on Virtual Instrument

Digital acquisition technique,dummy instrument technique and automated testing technique were taken to design a new-style testing system for a certain altimeter system.A new wireless-altimeter testing system was designed based on virtual instruments,the hardware circuit made of a PC-DAQ card and a digitizer,and a method that the Labwindows/CVI program controlled the course of digital acquisition and automated testing.It turns out that the testing accuracy is improved in combination with digital acquisition ...
