I this video I look at the output of a Low Distortion Sine Wave Board from AilExpress. I am using a Hewlett-Packard 331A Distortion Analyzer and as extras in the cast are a Spectrum Analyzer and an Oscilloscope. The board delivers a 1KHz nominal, 20dB, 7.75 Volt, 100mW across 600 Ohms. It is specified at 0.064 % distortion, I measured 0.01, as low as the HP could do.

Note that -124dB distortion is equivalent to 0.000064% not 0.0064%.

Very cool. I never knew RMS was a measurement of heat and the area of the sine wave. Thank you.

Built this I had to order the TL071 and I used CJR4556 high output op-amps from DigiKey. Works great with that combo.
