So rather than try to find and keep an almost-ideal programmable signal generator, I decided to build up a low-distortion Meacham-bulb-stabilized Wien-bridge oscillator using an ... the Agilent 33250A ...

Of all the low-frequency oscillator configurations, the Wien Bridge has to be the friendliest ... It uses standard components, gives a good sine wave and is fairly immune to the type of op amp ...

But the design goals are pretty clear: build an oscillator with as little distortion as possible across the audio frequency range. The basic circuit is the well-known Wien bridge oscillator where ...

The only problem with the Wien-bridge oscillator is that below unity gain it does not function. When working for a telephone company, I had to develop a 20-Hz, high-voltage sine-wave ringer circuit.
