Sweep your Function Generator
(Summer Circuits 2010 article)
Function generators built around the XR2206 have always had an excellent price/performance ratio, and the IC although ‘obsolescent’ is still available. If your generator does not have built-in sweep (‘wobbulator’) capability, a small external circuit is all you need. You can fit the circuit in place of the frequency adjustment potentiometer if you don’t already have a sweep input.
