1KHz Sine Wave Signal Generator Low Distortion High Precision Oscillator Board NE5532 Oscillator Adjustable Signal 1. 1KHz sine wave output with a distortion coefficient of only 0.000064%, suitable for high-precision testing applications. 2. Ultra low distortion design, with distortion less than 0.001%, ensuring signal purity and stability. 3. The power supply is ± 15V, with a current of only 30mA, making low-power operation more efficient and energy-saving. 4. Output voltage greater than 7V, suitable for harmonic distortion testing, level testing, and regenerative power supply scenarios. 5. Adopting the NE5532 chip, it has good performance and effective use. The capacitors that control the oscillation frequency on the board are selected and paired using a digital meter. The resistor that controls the oscillation frequency is a 3.3K resistor and a 200 ohm 3296 multi turn potentiometer connected in series. The pairing is adjusted by measuring with a digital meter to ensure the accuracy and low distortion of the output frequency.
