Ultra low distortion 1kHz fixed frequency sine generator assembled and tested PCB for distortions measuring applications. Fully analog schematic based on LM4562 opamp. Variable output voltage is provided by automatic gain control circuit. Require DC 35V external power supply for working (not included, but available by request). For the ultra low distortions measuring, PCB must be placed in shield.
(Some parts values may be different as on picture, cause the adjustment result)
