PNEV5180B AGC Value Inconsistency

[alig_ones]

I am using PNEV5180B V2.0 and I am trying to do DPC calibration. AN11742 document says:

You can see from the logs, I uploaded Type A protocol, switched RF ON and measured AGC, its 119, when I switch OFF RF its 336. Should I read AGC value when RF is OFF to see at least 300? Thank you.

Hello @alig_ones

Hope you are doing well.

On RF field off, AGC is configured for Card Mode. Please, take a look at PN5180 DPC Calibration | NXP Semiconductors; this video shows how to perform the calibration for the DPC using PN5180 Evaluation Board and NFC Cockpit.

Regards,
Eduardo.
