AGC

Thread Summary

The user reports that the AGC does not operate when APDLOWERCOUNT > 8 or HBUPPERCOUNT > 12, as observed in the instantaneous power of the signal at the end of the Rx datapath. The support engineer requested more details on the test conditions and AGC configuration, specifically whether Peak Detect Mode or Peak/Power Detect Mode is used. The user confirmed testing in Peak Detect Mode and that the AGC does not operate under these conditions.

BUGS

I have conducted numerous measurements and noticed the following constraints-limitations:

1)APDLOWERCOUNT: If apdlowercount>8 the AGC doesn't operate:

  

2) HBUPPERCOUNT: If hbuppercount > 12 AGC doesn't operate:

The figures above present the instantaneous power of the signal at the end of Rx datapath.
