But when I capture the tx shaping&nbsp; in the ISO14443A protocol with the Oscilloscope, there is a fluctuation on the falling transition.&nbsp; I&nbsp; upload the picture. Help me to&nbsp;analyze how it is so.</P><P>thanks a lot.</P><P><LI-PRODUCT title="PN5190" id="PN5190"></LI-PRODUCT>&nbsp;</P> Fri, 12 Dec 2025 03:02:44 GMT https://community.nxp.com/t5/NFC/PN5190-TX-shaping/m-p/2260600#M13909 Leo_3 2025-12-12T03:02:44Z https://community.nxp.com/t5/NFC/PN5190-TX-shaping/m-p/2262316#M13915 <P>For your information, please read</P> <P><A href="https://www.nxp.com/docs/en/application-note/AN13669.pdf" target="_blank">PN5190 questions and answers</A>&nbsp;- Chapter 3&nbsp;How to adjust TX wave shapes.</P> <P>And&nbsp;<A href="https://www.nxp.com/design/design-center/training/TIP-PN5190-DYNAMIC-POWER-CONTROL-DEMO" target="_blank">PN5190 Dynamic Power Control Quick Calibration and TxShaping Demo | NXP Semiconductors</A>.</P> <P>&nbsp;</P> <P>Hope this information help you.</P> Mon, 15 Dec 2025 07:02:11 GMT https://community.nxp.com/t5/NFC/PN5190-TX-shaping/m-p/2262316#M13915 jimmychan 2025-12-15T07:02:11Z
