I have the ADRV9008-1 w/PCB and I am trying to evaluate the AGC.
I have tested the AGC in manual mode and I see that I can modify the gain by changing the gain index.
Now, I am trying to configure the AGC to either peak or power mode. For this I go to the AGC tab in the TES tool and change 'AGC MODE' to 'Peak' or 'Power'. I leave the thresholds to the default values and click on 'Program'.
After doing this, I don't see the automatic AGC working. If I increase/decrease the input power the reported input power (receiver tab, Fund. Power[dBFs]) goes up/down by the same amount. I tried large changes to make sure that I am going across the thresholds.
Is my procedure for setting the AGC correct? Is there anything else that needs to be set to enable the AGC?
Click on the Update Rx chl tab in the AGC setting tab in order to save the AGC changes.
