There are several simple sine/triangle/square wave signal generators, with adjustible peak-to-peak voltage and voltage offset and duty cycle / symmetry. Their main use is for audio frequencies circuits and mechantronic circuits.

Frequency range is up to a couple of MHz, but at those frequencies the waveform is less than perfect. The front panel controls give an indication of the operating frequency, but if accuracy is required use scope or the frequency counter to measure the frequency.

These are all based around the classic ICL8038, which is effectively a 555 timer with some wave shaping. Consequently the sine waves are noticably distorted at the peaks, and they are unsuitable for serious audiophile purposes.
