High frequency accuracy ensures reliable signal generation. Deviation between input and actual output is less than 1% at high frequencies for precise results. Audible output and frequency dependent tone. The audio output level and tone follow the selected frequency; at low frequencies the human ear cannot hear the signal, but when the frequency enters the audible range a tone is produced for testing or demonstration. Robust construction with advanced materials. The generator uses a drift crystal oscillator at low temperature and a high-precision chip to deliver stable performance and improved interference immunity. Wide, precise sine wave range. Frequency stability is designed for consistency across applications, with sine waves adjustable from 0.01 Hz to 100,000 Hz for demanding tasks. Plug-and-play usability. Ready to connect with no complex setup, suitable for standard lab environments. Use scenarios - Calibrate audio equipment such as amplifiers, mixers, and loudspeakers. - Test sensors, ADC/DAC inputs, and measurement channels with known frequency signals. - Educational demonstrations and lab experiments on frequency, resonance, and signal processing.
