MAS-8400
Audio Analyzer + AM/FM Stereo Signal Generator




This audio analyzer MAS-8400 series consists of Audio Analyzer and AM/FM Stereo Standard Signal Generator functions in a compact and light weight body. MAS-8400 series also consists of High Speed Processing by DSP and FFT (Fast Fourier Transform) Analyzing features which could shorten the measurement speed by 70%. All these performances exceeds ancestor models. As for external interface, USB, Ethernet are equipped for high speed transmission with PC or server. In addition, Audio Analyzer equips spectrum display function of the input signal.

MAS-8400: This model incorporates Audio Measuring Section and RF SG section. This model can be used to evaluate or test such as Tuner of Radio, Car Navigation System or Audio amplifier.

For Component Stereo and Car-Navigation System
