https://devzone.nordicsemi.com/f/nordic-q-a/116106/nrf52832-large-rssi-errors-vs-input-powerHello, I am currently checking the RSSI measurement precision, and we got very large errors (up to 10dB error) on the RSSI vs input power. To avoid any PCB / matching issues, we use the nRF52832 DK board, connected to an RF source via the coax connectoren-USTelligent Community 13Fri, 15 Nov 2024 08:01:53 GMThttps://devzone.nordicsemi.com/thread/510614?ContentTypeID=1Fri, 15 Nov 2024 08:01:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e0bd273d-65b0-4625-b21e-3ad3e8e5249amathiaso[quote user=""]Does the RSSI need a modulated signal instead of a CW signal?[/quote] <p>Could you try measuring with a 1 Mbps BLE modulated signal instead?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/509203?ContentTypeID=1Wed, 06 Nov 2024 09:20:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d0f65f33-eeb2-47dd-adf8-c6735717d09bmathiaso<p>Hi, Florent.</p> <p>There can be several factors that affect the measured RSSI value.</p> <p>Could you provide, e.g., a table of the values you are measuring vs. the values you are expecting?</p> <p>Could you also please describe your setup in even more detail?</p> <p>Best regards,<br />Mathias</p><div style="clear:both;"></div>
