Ultra low distortion 1kHz fixed frequency sine generator assembled and tested PCB for distortions measuring applications. Fully analog schematic based on LME49720 opamp. Variable output voltage is provided by automatic gain control circuit. Require single isolated DC 35V external power supply for working (not included) - LM317 or LM317HV based supply is good enough. For the ultra low distortions measuring, PCB must be placed in shield. Improved version (4-th step) of this generator is on sale now . Typical performance of this generator ( measured by my tools ) now is less than -145dB (<0.055ppm) level of second and third harmonics. (Some parts and values may be different as on picture, cause the adjustment result and improvement) Specifications: Second and third harmonic levels unloaded or loaded 600ohm                            < 0.1 ppm ( < 0.00001%) Output frequency                                           1kHz +/- 1% Unloaded output voltage level                          300mV - 2.6V (RMS)                               Output impedance                                          600 ohm External power supply DC voltage/current        35V / 25mA Dimensions (W x D x H) / Weight                    60mm x 70mm (50mm - board) x 27mm /   20g *Gold plated RCA sockets. *Power on LED indicator. *Output level regulator. *GND terminal. *Two year warranty. 10kHz similar generator is also available : Ultra low distortion (<0.00005%) 10kHz sine generator assembled and tested PCB Other audio frequency ultra low distortion similar generators available by request.
