- Robust performance with a low temperature-drift crystal oscillator and a high-precision chip, delivering stable operation and stronger interference resistance. - High frequency accuracy: input-output deviation under 1% at higher frequencies. Audio output follows the frequency; at very low frequencies the ear cannot hear it, but when the frequency reaches the hearing range and the speakers are connected, sound is produced. - Enclosed housing provides protection and portability, enabling flexible integration into existing setups. - Type-C power interface supports use in homes, studios, research labs, or any environment where stable frequency generation is important. Use scenarios: - In a home studio, for tone generation, calibration, and testing of audio equipment. - In a research lab, as a stable frequency reference for experiments. - In educational or professional testing environments, for device calibration and signal generation.
