Hi, I'm a hobbyist musician with pretty much no electrical knowledge. I want to buy a used Ossilator or something similar just to add weird electronic noises to a piece of music. What is the difference between an oscillator and a signal generator? How can I tell if a device is set up to create audio? Some devices I've seen online have RF outputs, can you take audio from an RF output?
Any help would be much appreciated. Thanks.

What is the difference between an oscillator and a signal generator?

All signal generators contain an oscillator of some type. The difference is the SigGen will have a buffered output to present a low resistance at the output terminal, typically 50 ohms. It can also have facilities to adjest output voltage, frequency, etc.

How can I tell if a device is set up to create audio?

Look for an audio signal generator. Any signal generator who's frequency is between 20hz and 20khz will work for audio.

Some devices I've seen online have RF outputs, can you take audio from an RF output?

No. RF signal generators are not useful for audio.

Any help would be much appreciated. Thanks.

You're welcome!

 

This May be what you are seeking "Music from Outer Space" has a few oscillators, noise generators, and envelope control.

It's a DIY portable version of the old Analog synthesizers (Moog used by ELP [Emerson, Lake, and Palmer] in the 1970s, for example).

 

Hello,

Also the "Weird Sound Generator" can be found on "Music From Outer Space":
