My understanding is that a function generator is used to generate different types of waveforms to check distortion and linearity in conjunction with a oscilloscope.
A signal generator generates a rf carrier (or modulated carrier) at a specific frequency. If your generator can produce a clean modulated carrier @1300kc then your OK. Truth be told you could use a local broadcast signal on or near that frequency.
But what the heck do I know??
