叙述PXI总线虚拟仪器的特点和应用领域。分析了测控类雷达发射机对自动化测试系统的需求以及基于PXI总线虚拟仪器测试系统对于测控类雷达发射机指标测试需求的满足程度。提出了基于PXI总线的虚拟仪器理念构建测控雷达发射机自动化测试系统的设计方法,并介绍了无法直接测试指标的软件计算方法。最后,举例说明实际应用产品的使用效果,以及自动化测试系统的意义。
Describe the characteristics of PXI bus virtual instrument and application areas. The demand of the test and control radar transmitter for the automated test system and the satisfaction degree of the PXI bus virtual instrument test system for the test of the test and control radar transmitter index are analyzed. A virtual instrument concept based on PXI bus is proposed to construct the design method of automatic test system for the measurement and control radar transmitter. The software calculation method which can not directly test the index is introduced. Finally, an example of the practical application of the product performance, as well as the significance of automated test system.
