Hi Hiroyuki-san,

The same question has been discussed in the following thread.

AWR1843BOOST: Can mmwave demo visualizer find the received power? - Sensors forum - Sensors - TI E2E support forums

Please let me know if you have any further questions. If not, kindly mark the thread as resolved.

Regards,

I understand that the received power is converted to dB and that scaling is performed by the ADC.

thank you for your politeness.

However, we do not know what power is used as a reference for converting the received power unit to dB.
Could you tell me a little more about that?

In addition, please post any documentation that mentions scaling.

Hi Hiroyuki-san,

The full-scale power of the Rx ADC (Maximum range of value that can be captured) itself is the reference against which the actual received power is scaled.

Unfortunately, we do not have a document for this.
