This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The signal pattern is similar to a bird’s chirp. The pulse width of the trigger signal must be a minimum of 2.5 miliseconds.

FM/AM Frequency Generator Recommendations | diyAudio

I own a HP 8656B rf sg, I measure thd at around ~0.1-0.3%, depending on freq, using the HP 8901A and a Amber 3501. Even if I use the Amber 3501 audio osc, it makes no difference. I believe the majority of thd is in the 8656B. I bought a HP 11715-60001 rf assembly (from a HP 11715A test set) to play with.

If you want to try a more advanced and more accurate version see the DIY Signal Generator II. This diagram shows how the circuit can be wired without the need for any circuit board. A 14 pin IC socket is used to hold the main circuit so the 555 chip and the two pots can be simply plugged in. The total parts list is shown below. 14 pin IC Socket.

Therefore, you can have a signal generator whose frequency can be controlled by an external circuit (more specifically, an external voltage). This could be used for FM generation or to create a close loop feedback where the frequency generated is turned into a voltage which in turn controls the VCO. Project Files. DIY Signal Generator Files
