Fast AGC State when there is no signal?

What will be the state of Fast AGC when there is no signal?

 

The receiver only sees noise. In my expectation, even with maximum gain, the amplified noise cannot reach the targeted AGC lock level. Therefore, the fast AGC will be in a pingpong operation switching between state 1 to state 2. In state 2, due to low power condition, fast AGC moves back to state 1. In state 1, since there is no over range, fast AGC goes to state 2 immediately.

 

Right?
