Overview
Low distortion coefficient sine wave oscillator board, oscillation frequency: 1 KHz, ultra-low distortion, distortion coefficient 0.000064% (-124dB). It can be used for harmonic distortion testing, level testing, regenerative power supply, etc. The board controls the oscillation frequency.
The capacitors controlling the oscillation frequency on the board are selected and paired with a digital meter, and the resistor controlling the oscillation frequency is a 3.3K resistor and a 200-ohm 3296 multi-turn potentiometer connected in series, which is adjusted and paired with a digital meter to ensure the accuracy of the output frequency and low distortion.
Notes:
1, theoretically, R10 = 2R13, C3 = 2C4, distortion is minimized.
2, the data in the figure for the value of 1KHZ, if the other frequency, in addition to R6, R7, C1, C2 need to be adjusted accordingly, R11 should be modified according to the frequency.
For example: 50HZ, R11=447K, 60HZ, R11=408K.
