摘要
分辨率带宽(RBW)是衡量频谱分析仪性能的重要指标,寻求高效的测试方法对于改进频谱分析仪设备的计量工作有着重要的意义。利用现代数字频谱仪提供的读取轨迹的功能,通过计算机分析处理获取的轨迹数据来得到3dB带宽和60dB带宽。这种方法利用了计算机的数据处理优势,大大提高了测试效率。
Resolution bandwidth (RBW) is a main performance indicator of spectrum analyzer. It's very important to develop efficient test method for RBW measurement. In this paper, we make use the function of reading trace data of spectrum analyzer and data processing of computer to obtain 3dB bandwidth and 60dB bandwidth. This method utilizes the advantage of data processing of computer, and improves test efficiency greatly.
