Design and implementation of oriented virtual integrated testing system based on low-speed DAQ

Shi Yong, Wang Fan(PLA Team 73682 , Xuzhou 221006, China)  
The fast development of computer technology drives the computer based virtual integrated becoming more and more important in the measurement field. In this paper, a low-speed DAQ oriented virtual integrated testing system is designed and implemented on the hardware PXi-6070E DAQ Card in the measurement automation explorer and LabVIEW graphical program environment. The low-speed sampling rate is 1.25 Mb/s and the system contains several modules such as data acquisition, spectrum analysis, waveform display, time-domain measurement, frequency-domain measurement and simple signal generating. The paper demonstrated the development flow, the software and hardware environments and the programming implementation of the low-speed DAQ oriented virtual integrated testing system, and brought out the measurement front panel of the low-speed DAQ oriented virtual integrated testing system too.
