Vibration Analyzers: Spectrum Analyzers for Sound and Vibration Analysis

In this article we will tell you about spectrum analyzers for sound and vibration measurement with enough detail so that you will: See what spectrum analyzers are and how they differ from vibration analyzers Learn how spectrum analyzers work Understand how spectrum analyzers are used today Are you ready to get started? Let’s go! Introduction This article will focus on real-time spectrum analyzers for sound and vibration measurements. These instruments are used for data acquisition and analysis in the frequency range between DC and several megahertz. This includes the full range of sound signals from infrasound to ultrasound. For some applications, a spectrum analyzer is referred to as a vibration analyzer.

For application domains like telecommunication where the frequency range of interest is in the MHz to GHz range, other types of spectrum analyzers must be used. These are typically referred to as RF spectrum analyzers. What Is a Spectrum Analyzer? A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument. The primary use is to measure the power of the spectrum of known and unknown signals A spectrum analyzer is an instrument that measures the magnitude of an input signal over a range in the frequency domain. The primary use is to measure the power of the spectrum of known and unknown signals. On top of that, spectrum analyzers often have tools and features for deeper signal analysis suitable for different application domains. What is Spectrum? A Spectrum is a graphical representation of the signal as a function of a dependent variable. A sound spectrum, for example, is a representation of a sound – usually a short sample of a sound – in terms of the amount of vibration at each individual frequency. It is usually presented as a graph of either power or pressure as a function of frequency. The power or pressure is usually measured in decibels and the frequency is measured in vibrations per second (or hertz, abbreviation Hz) or thousands of vibrations per second (kilohertz, abbreviation kHz).
