https://devzone.nordicsemi.com/f/nordic-q-a/32948/tx-carrier-frequency-accuracy-and-current-measurementHello, my first question is about TX carrier frequency accuracy measurement. The equation given in the whtie papers is (|f_measured - f_programmed|) / f_programmed &lt;= M * 10 ^ -6 I measured the carrier frequency on the channels 0, 40 and 80 of theen-USTelligent Community 13Tue, 03 Apr 2018 08:53:47 GMThttps://devzone.nordicsemi.com/thread/126608?ContentTypeID=1Tue, 03 Apr 2018 08:53:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:58267863-2a15-4a0b-9d51-7ce8a96fb823haakonsh<p>Hey DanKA,</p> <p>6.503 kHz absolute offset is a good result, as expected of a proper design, nothing to worry about there.&nbsp;</p> <p>Your measurements looks spot-on:<br /><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-91e5965083b14b5480ae6219e8347235/Current.PNG" alt=" " /></p> <p>&nbsp;</p> <p>See&nbsp;<a href="https://devzone.nordicsemi.com/power/">https://devzone.nordicsemi.com/power/</a>&nbsp;for more details of the graphs. The number is only valied for the nRF52832, but the detailed information of the different radio states is worth checking out.&nbsp;&nbsp;</p> <p>Cheers,</p> <p>Håkon.</p><div style="clear:both;"></div>
