    Hi,
    

    Can you please help me how to measure system level Rx Sensitivity when we use AD9363 Transceiver in design?
    

    Thanks,
    

    Ram

      HI  
      

      Use the thermal noise formula:
      

      Noise Power (dBm)=−174+10log⁡10(BW in Hz)+NF (dB)\text{Noise Power (dBm)} = -174 + 10\log_{10}(\text{BW in Hz}) + \text{NF (dB)}Noise Power (dBm)=−174+10log10​(BW in Hz)+NF (dB)
      

      Example for 1 MHz BW and NF = 6 dB:
      

      −174+10log⁡10(106)+6=−174+60+6=−108 dBm-174 + 10\log_{10}(10^6) + 6 = -174 + 60 + 6 = -108 \text{ dBm}−174+10log10​(106)+6=−174+60+6=−108 dBm
      

      Add required SNR for modulation (e.g., QPSK ~10 dB):
      

      Sensitivity≈−98 dBm\text{Sensitivity} \approx -98 \text{ dBm}Sensitivity≈−98 dBm

      Please find below Measurement Steps

        

      1. Setup Test Equipment:

          

        • Use a calibrated RF signal generator.
          • 

        • Connect to AD9363 RX input via attenuators and cables.
          • 

        

        2. 

      2. Configure AD9363:

          

        • Set LO frequency, bandwidth, and gain mode (manual or AGC).
          • 

        • Ensure proper calibration (DC offset, quadrature).
          • 

        

        3. 

      3. Define Performance Metric:

          

        • For digital: BER or EVM using known waveform (e.g., QPSK, LTE).
          • 

        • For analog: SINAD or SNR.
          • 

        

        4. 

      4. Procedure:

          

        • Start with a strong signal (e.g., -50 dBm).
          • 

        • Gradually reduce input power in 1 dB steps.
          • 

        • Record the point where BER/EVM crosses the acceptable threshold (e.g., BER < 10⁻³ or EVM < 8%).
          • 

        

        5. 

      5. Repeat for Different Bandwidths and Gains:

          

        • Sensitivity varies with bandwidth and gain settings.
          • 

        

        6.
