I don’t know what you mean - the noise generator has a frequency setting because you can change the frequency at which the random values are generated. So if you sweep up the frequency it will become white noise, if you sweep it down it becomes rumbling “arcade” type noise.
True white noise has energy for all frequencies of the spectrum, so @NeilParfitt is right that if you want to “pitch” that you have to run it through a filter and play with the cutoff, for example.
The noise generator in the SSP’s software can be switched to “White” or “Toggle”. In white mode it outputs true white noise and in Toggle it outputs the noise with variable frequency.
