I'm following the antenna tuning procedure in AN11019 - "CLRC663, MFRC630, SLRC610 Antenna Design Guide." Section 4.2.1.6 discusses measuring the impedance of the antenna with the matching network and the IC (CLRC663 in my case) in place. It is not clear from the documentation, however, whether or not the NFC chip should be powered at the time of measurement. Can you please clarify?
Thanks
