In the case, the Reader output power cannot be further reduced with the help of the tuning and TXLDO settings (e.g. EMI reasons)
Then further reduction can be done using DPC settings. The idea is to use just one DPC entry and adjust the GSN value as shown below:
DPC Settings:

The DPC Entries (1-19) have been deactivated (Index Activate ->0), and only Entry 00 stays active.

An example (RF Field measured using a scope probe):
No DPC, TXLDO 5V

DPC Activated, One Entry, GSN-> 0x05

DPC Activated, One Entry, GSN-> 0x01

Please consider that the reading performance will be impacted.
