Power Level vs. Noise floor

I have noticed that the noise floor of the measurement increases as the port power is decreased.

Can someone one enlighten me on the cause of this relationship? My best guess is that internally the power detector output is being compared to the port power, which acts as a reference power level.

Any input will be appreciated.
