基于PXI总线的雷达装备通用模块接口电路设计

为做好对部队雷达装备日常性能的检测与维护，充分保障其性能的可靠性，研制开发了基于PXI总线的雷达装备性能检测模块。在对模块的接口电路的设计中，采用目前流行的PCI9030接口芯片，简化了设计难度。经实验验证，采用该方案的各模块都实现了相应的功能，达到了预期的设计目的。需要改进的方面是接口电路中热插拔部分性能的可靠性有待进一步提高。

Design of the Interface Circuit of General Modules Used for Radar Equipment Based on PXI Bus

In order to do well in the test and maintance of daily performance of radar equipment, and guar- antee the credibility of the performance, a series of modules based on PXI bus which are used for the performance test of radar equipment are developed. In the design of the interface circuit of the modules, PCI9030 as a kind of popular interface chip for the moment is used to simplify the design to a certain degree. The experiment shows that the modules which use this scheme all realize their respective functions, and the anticipated design purpose is achieved. On the other hand, the aspect that needs to improve is the stability of the hot swap circuit.
