I get the IQ data and configuration from serial as: DF_BEGIN [&#39;IQ&#39;, 0, 0, 11, -9, -213] [&#39;IQ&#39;, 1, 8, 11, -209, 23] [&#39;IQ&#39;, 2, 16, 11, 38, 208] [&#39;IQ&#39;, 3, 24, 11, 214, -32] [&#39;IQ&#39;, 4, 32, 11, -43, -212] [&#39;IQ&#39;en-USTelligent Community 13Mon, 28 Jul 2025 13:12:31 GMThttps://devzone.nordicsemi.com/thread/543758?ContentTypeID=1Mon, 28 Jul 2025 13:12:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:16aa0f5e-9df6-442b-aa35-b1b4464d8f15Simonr<p>Hi</p> <p>I agree that the documentation is a bit poor here, but these numbers refer to the register values of the switch spacing, sample spacing ref, and sample spacing from the DFECTRL1 register of the<a href="https://docs.nordicsemi.com/bundle/ps_nrf52833/page/radio.html#ariaid-title111"> nRF52833 PS</a>.</p> <p>So these would mean the following:</p> <p>SW: 2 = 2µs<br />RR: 3 = 1µs<br />SS: 3 = 2µs<br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1753708344582v1.png" alt=" " /></p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
