https://devzone.nordicsemi.com/f/nordic-q-a/98330/how-to-measure-rf-tx-power-of-the-transmitterHi, We are using nRF52833 in our lighting product application. As per the datasheet of nRF52833, Tx Power is variable from -40dbm to +8dbm. In our application, we are setting up a radio transmitter of nRF52833 transmit to transmit at +8dbm output poweren-USTelligent Community 13Mon, 17 Apr 2023 11:21:59 GMThttps://devzone.nordicsemi.com/thread/420741?ContentTypeID=1Mon, 17 Apr 2023 11:21:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:606bb625-8170-41c9-ad5b-afb4c3759614RameshS<p>Hi Bendik,</p> <p>Thank you for your support.&nbsp;<span>As per the datasheet of nRF52833, Tx Power is variable from -40dbm to +8dbm.&nbsp;Nordic must have verified this and Nordic may be having the test results.

The power can be measure either radiated or conducted. The radiated measurement need a reference antenna for the spectrum analyzer, and will most likely not be very accurate without a shielded test environment. The best and easiest solution is to do the measurements conducted, with either a test connector(if one is present on the board) or with coaxial cable soldered to the transmission line.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
