摘要/Abstract：
本系统是一个基于软件无线电的无线信号记录仪，它以虚拟仪器概念为基础、结合微电子技术和计算机技术，利用NI公司的高速采集板卡5622、FPGA和计算机实现。测试结果表明，本记录仪可以长时间记录无线信号，并具有实时解调的功能。用户可以在最短时间内得到信号质量的相关信息，进而判断信号源的工作状态。本仪器可用于无线通信设备的测试，能够简化测试过程，节省人力。系统设计中着重于解决高采样率时数据的高速传输和存储问题。
This system is a wireless signal recorder based on the software radio. Laying the foundation on the virtual instrument technology, combining the microelectronics technology and the computer technology , the wireless signal recorder which can take samples continuously is composed from a PXI-E5622 ADC、a virtex5 FPGA and a computer. Owing to the function of demodulation, it’s easy to get to know the quality of the signal and to judge the working state of the signal source. The recorder will simplify the testing process and save manual labor when used in the test of wireless communication equipment.
