BY-403 provides a complete solution for the FM simulation signal. The device focuses on the following functions: RF amplifier, FM modem, stereo demodulator, RDS decoder, SCA decoder, FFT spectrum analyzer. BY using the most advanced DSP technology in the field of digital processing, BY-403, it is an innovation for the former FM simulation processing performance.

BY-403 all-in-one FM modulation monitor is a broadband FM monitor that meets the requirements of the federal communications commission to measure the modulation characteristics of mono and stereo multiplexed FM transmitters. BY-403 measurement modulated signal and provide high quality output service for the traditional analog FM radio station working at 88MHz - 108MHz. The equipment can carry out the spectrum analysis of pre-demodulation and post-demodulation signal, and the internal calibration signal will monitor the detection accuracy in real time. Through a communication port, the customer can remotely monitor BY-403 via computer.
