RX AGC Issue removing attenuation

Category: Software
Product Number: ADRV9002

I am trying to configure the RX AGC in auto mode and am having trouble getting the AGC to put gain back in after removing input signal.

We can get it to react to an input signal.

But when we remove the signal it doesnt put the gain back(attenuation lower).

I have highThresh of 26 and low of 12.

I think that means -6 dBFS and -13 dbFS.

Are these numbers correct in reference to dbFS?
