Abstract


Traditional security command receiver test system includes dedicated equipment and general instrumentation , interconnection complexity , complicated operation , space and test time is relatively long , more prone to human operator error and testing error . The project developed automated test system , the standard PXI chassis with the controller , multi-function card , vector signal generator , AC / DC power supply and homemade control conditioning card module with automated testing software automatic test automatic monitoring , automatic storage , automatic reporting and other functions , to solve the problem of safety instruction receiver high density test . Automated testing software as the core of the entire system , software development is a key part of the entire development over . Author LabVIEW software platform , the use of a three-tier structure of the software , completed an independent software developers to write the work , and involved in software testing and test of the entire system work . In the software development process , to solve the problems, such as DPSK signal modulation , analog carrier generation software trigger signal the use of radio frequency test and final vector signal generator output contains the password information the DPSK modulated carrier signal docking with the receiver test .
