Built with a low temperature drift crystal oscillator and a precision chip, this generator delivers robust performance and strong resistance to interference. When the frequency is , the inputoutput deviation is less than 1%. The sound output of connected speakers is determined by the frequency. At very low frequencies, the human ear cannot hear it; if the speakers are connected and the frequency enters the audible range, sound will be produced. Enclosed housing provides added protection and portability, enabling flexible integration into existing setups. Suitable for use in home studios, research labs, or any environment where stable frequency generation is important, thanks to its Type C power interfaces. Use scenarios and applications Home studio: generate precise reference tones for calibrating monitors and testing audio gear, enabling accurate sound reproduction and system checks. Research laboratory: provide stable, repeatable frequency references for experiments, signal characterization, and instrument benchmarking. Education or development environments: support diagnostics, calibration, and testing of electronic equipment in environments that require consistent frequency generation.
