AWR2944: 2944 rxGain value detail

wu qiang

Part Number: AWR2944

I see DAC & RSSI in the picture above,I want to know few questions:

1.how to get the value of DAC & RSSI,is there any API in ICD?

2.in SDK,I can set the rxGain,this rxGain includes which part (LNA, mixer, filter, IFA, ADC.etc)'s power ?How can I get the whole chain's gain.

Hello,

Sorry didn't realize the link was internal only. I'll just paste it here and you should be able to see the second thread. Please let me know if any issues and on #1, we will update you as soon as possible.

RX_Gain_Value reports the total RX gain applied. This includes both the RF gain and the IFA gain.
IFA_Gain_Exp is the expected IFA gain value that the device plans to apply. It’s typically calculated as IFA gain= RX gain - RF gain
RX_IFA_Gain_Error reports the deviation between the actual IFA gain and the expected value to help detect gain drift or calibration mismatch.

Thanks,

Aydin
