3 Overview

The FFT dynamic signal analyzer (hereinafter referred to as the analyzer) is composed of hardware and analysis software, and can be represented from An instrument that analyzes its characteristic parameters in a physical quantity of electrical signals, which can analyze the measured signal from the time domain, the frequency domain, and the amplitude domain. It is widely used in features such as full function, fast analysis speed, many measurement parameters, high frequency resolution and high amplitude accuracy. Measurement and analysis of mechanical quantities such as vibration and shock.
