What kind? A standard signal generator might generate sine, square, triangle and ramp output waves. Newer arbitrary waveform signal generators can generate any kind of waveform you could think of.i'm looking to use a signal generator for musical purposes.
Well, not for the audio spectrum. However, it would be a good idea to use a coaxial cable of the same impedance that the signal generator outputs, until you can match it to your line input signal.I'm just not sure what i would need to send the audio output to some sort of amplifier. is an RF cable necessary?
What, precision tone generators?Should i be looking for pitch generators?
Well, older signal/waveform generators were purely analog. The newer ones use DACs. You can hardly find decent analog waveform generation ICs anymore. The 566 and MAX038 have been gone for a few years now.Is a DAC essential?
