The SZDS electroacoustic testing system is an indispensable testing equipment for the design, development, and production of electroacoustic products. The SZDS electroacoustic testing system is developed and designed according to national or international standards, and consists of two parts: hardware and software. The hardware system adopts a USB interface collector, which is connected to a laptop (or desktop) computer. It is both plug and use, flexible and convenient, suitable for on-site measurement and online detection; The software system can programmatically generate over ten types of signals, including sine wave, square wave, triangular wave, white noise, pink noise, etc; By using methods such as one-third octave and FFT analysis, the frequency and time-domain response of the tested electroacoustic product can be analyzed, which can measure the frequency response, harmonic distortion, impedance, instantaneous pulse response, and other characteristics of the electroacoustic product. It can also perform spectrum attenuation and residual (RT60) analysis, providing multiple scanning signals and QC detection methods to measure the total harmonic distortion, intermodulation distortion, signal-to-noise ratio Quickly test parameters such as sound pressure level frequency response and impedance characteristics, and analyze and evaluate the causes of non conformities in the tested products. The high-quality data management of the system and computer-based measurement functions are particularly focused on meeting the unique requirements of product development and QC testing. Whether your purpose is professional research, engineering application, and product quality inspection, the SZDS electroacoustic testing and analysis system is an ideal choice. No other measurement tool today can provide so many outstanding features and functions at such a low price. The SZDS electroacoustic measurement system is widely used for engineering quality testing and electroacoustic analysis of various electroacoustic products such as audio, speaker units, speakers, headphones, microphones, CDs, VCDs, DVDs, amplifiers, communication equipment, buzzers, etc
