噪声测试平台的软硬件实现

Hardware and Software Realization of Noise Measurement Platform

为了提高噪声测试仪器使用效率,缩短测试周期,给出了一种噪声测试硬件平台的具体搭建方式及其配套软件的编写过程。硬件平台包括Agilent346C,HP8970B,HP8971C,HP8341B,Agilent82357A及GPIB连接线等。软件平台用Microsoft Visual C++6.0编程实现,通过GPIB接口对测试仪器进行控制,执行仪器校准、测量数据、将数据读入计算机,并能够将测试结果以文本和图形化方式显示出来,实现自动化测试。该噪声测试平台能够测量的最高频率为20 GHz。
