介绍了一种雷达频综组件的自动测试系统,该系统基于PXI 总线平台,采用美国国家仪器公司(NI)Labwindows/ CVI软件开发环境,利用NI 的数字波形发生器PXI-6541 取代人工控制盒产生频控信号,结合通用接口总线接口技术实现仪表控制和数据采集。通过验证,调试周期缩短三分之二,测试界面简单友好,具有操作简单、使用方便、测试效率高等优点。

A kind of automatic test system of the radar frequency synthesizer module is introduced in this paper. The system is designed based on PXI bus, developed with the environment of National Instruments ( NI) Labwindows/ CVI and it realizes many functions as instrument controlling and data acquisition in combination with general purpose interface bus interface technology. NI digital waveform generator PXI-6541 is used to replace the manual control box to produce frequency-control signal. Practice has proved that the debugging cycle is reduced by two thirds. And the test interface is simple and friendly. The system has the advantages of simple operation, convenient use and high test efficiency.
