The latest virtual instrument and automatic test technology are adopted. One set of UAV avionics automatic test system for comprehensively testing radio altimeter, diastimeter anti-collision and alarm system, radio compass and multi-mode receiver is designed based on PXI module and GPIB instrument. Realization concept of key technologies, such as software and hardware design method, interface adaptation,...
Harmonic impedance is an efficient instrument to assess the state of a harmonic polluted grid, to anticipate unfavorable operating regimes and the selection of means of intervention. The monitoring and then use that information in expert systems for optimizing the basic operating regimes will be attributes of smart grids of the future. This article presents a virtual instrument built using National...
This paper presents an intelligent testing system for underwater transducer array by using virtual instrument technology. The testing system is used to test the identities between transducer and transducer of the underwater transducer array. The hardware and software architecture of the testing system are introduced. The system software is developed on the LabVIEW. LabVIEW, a graphical programming...
To meet the increasing demands of prototype testing of synchronous generators, a novel testing system using virtual instrumentation technology is designed and implemented on LabVIEW platform. It consists of control computer, sensors, signal regulation, conversion modules and PXI data acquisition module. This system can easily and gradually control the workload of the generator and accurately measures...
Membrane switches are widely used in electronic interface devices, namely computer, point-of-purchase, telecommunication and industrial equipments. To increase the quality of their products, membrane switch manufacturers are required to maintain control over their products with an important quality to be tested which is the membrane switch resistance. However the test equipment is not commercially...
