一、概述 2032/2034双通道信号分析系统是丹麦布鲁爱尔克稚(Brel & Kjzer)公司经过五年研制于去年投入市场的一种先进的设备,也是一台具有双通道傅里叶分析特性、采用非易失存储器、自动选择量程、自动标度、全数字频谱展宽、软件固化、32位信号与显示处理器的快速分析系统,见图1。2032/2034不仅包括全部34个预先设定的典型功能,而且这些函数都可被增强(enhace)。采用801条谱线测量两种不同方法的频率响应函数,通过希尔伯特变换还可计算并显示全部时间函数的包络。振动与声传感器都可直接连到分析系统,用户以工程单
I. Overview 2032/2034 dual-channel signal analysis system is a state-of-the-art device launched by Brel & Kjzer Company in Denmark last five years. It is also a dual-channel Fourier analysis Features, Fast Analysis System with Non-Volatile Memory, Automatic Range Selection, Auto-Scaling, All Digital Spectrum Spread, Software Curing, 32-Bit Signal and Display Processor See Figure 1.2032 / 2034 Includes Not Only All 34 Predefined The typical function, and these functions can be enhanced (enhace). Using 801 spectral lines to measure the frequency response function of two different methods, the Hilbert transform can also calculate and display the envelope of the entire time function. Vibration and acoustic sensors can be directly connected to the analysis system, the user to a single project
