https://devzone.nordicsemi.com/f/nordic-q-a/52983/set-tx-power-on-nrf9160Hi, I&#39;m currently making energy measurments with an nrf9160 DK. The software project is based on the udp_with_psm sample. I would like to run the test on different tx-power levels. I have seen that the tx power can be adapted with the AT%XRFTEST,en-USTelligent Community 13Tue, 08 Oct 2019 10:27:00 GMThttps://devzone.nordicsemi.com/thread/213851?ContentTypeID=1Tue, 08 Oct 2019 10:27:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61f0b6d8-7a70-45e9-af3d-857c0ad5d5f8H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>There is no way to change or limit the output power manually on the nRF9160. The cell tower will drive this communication, and tell you to use a lower output power setting if the link budget is good when communicating with it.</p> <p>%XRFTEST is a RF test mode, where it can be set in different modes; but be sure to test this in a RF-chamber, as you&#39;re dealing with licensed bands.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
