摘要
本文以HP3582A频谱分析仪为例,扼要介绍以快速付里叶变换(FFT)算法为基础的频谱分析仪的原理及其在电子机械工程领域里的应用,例如:机械和设备的诊断;机、电及音响系统传递函数的测量;现场动平衡以及干扰源的分析等等。
Taking the HP3582 A spectrum analyzer as an example, this paper deals with spectrum analyzer principle based on FFT and its typical uses in the fields of electronic mechanical engineering, such as diagnoses of machinery and equi pments; measurements of transfer function in mechanical and electroacoustic systems: field balance technique and interference survey, etc.
