https://devzone.nordicsemi.com/f/nordic-q-a/71297/what-per-threshold-of-rx-sensitivityDear Sir, I&#39;m testing the Rx sensitivity of EVB (nrf52840-DK). I use PER 30% be the thresholde and get Rx sensitivity; -92 dBm/ 1M , -88dBm/2M. It&#39;s different with datasheet -95 dBm/ 1M , -92dBm/2M. What PER threshold of RX sensitivity ??

There may be some variations over the 2.4GHz band due to un-linearities, and also some variations due to production lots, however I suspect that it may be mostly due to loss in cable and connectors.&nbsp;</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
