Query: Random Noise general

When I first saw the Pink Stick, really, I didn't expect that is the noise generator, it is more like a larger lips stick, but after I found out its functions, it really helps me a lot, especially when I teach students how to use realtime analyzer in the school, you just plug in to the mono mic input of the mixer, turn on the phantom power, select the noise you want, then push up the fader, you can get what you want, thanks for the considerate design for a person like me.
