【正文】 31 module to create an 8 128 crosspoint switch matrix to the PXI measurement module connected to all points on the mass interconnect interface test adapters (ITA). With this switch matrix, we have to connect to the ITA DUT (UUT) to achieve full functional test configurations all the required connections. Additionally, we will VME interface is integrated into the test system and connect it to the ITA, which provides for each UUT prehensive VME bus test.Integrated NI PXI and LabVIEW, NI TestStand We primarily written in LabVIEW and NI TestStand test systems test assembly. By eliminating the need to write custom drivers, NI software greatly simplifies the hardware and software systems integration. After starting the program, LabVIEW will call each PXI modules for selftest operation, check the calibration date is valid, and then the functional tests. Each test written in LabVIEW, NI TestStand to call in the execution. The end of the test execution, the test will be based on the collected data and generate a readable report can be exported in XML format.NI Technology List Our application through the NI PXI8108 embedded controller to achieve the management tasks through the NI PXI6653 and NI PXI6651 module to control the timing and synchronization. For the connection, cycle puting and munications, we use NI PXI7813R to achieve data integration, NI PXI7853R module process connection and signal processing as well as NI PXI7854R module for signal processing. In order to develop the current stabilization system, we use NI LabVIEW 2010 software, LabVIEW FPGA Module and the LabVIEW RealTime Module. Development process largely depends on training and NI LabVIEW volume license agreement.Changing views on Compact ATS Orbis will PXIbased test system with a custom ITA and VME interfaces bine design and build a prototype called Compact Tester test system. Compact Tester with 12 cubic feet of 18slot PXI chassis test system replaces the 84 cubic feet of test systems. Compared with the previous test systems, cost reduction of 3 times, 15 times smaller footprint, weight 25 times, this difference is very significant. In addition, the use of industrystandard PXI hardware and LabVIEW software, we were also able to reduce the daily operation and maintenance costs. In addition to achieving all the goals set for the Compact Tester, the PXIbased system also has other advantages. Interconnection due to the size and mass reduction, thereby pleting the number of cables required for each test is significantly reduced. Which in turn all
