How ?
- Modify the input attenuation value of the spectrum analyzer.
The "gain" parameter will allow you to change this. Please ensure the input signal is below -20dBm to avoid damage to the receiver.
- Know the relationship between the attenuation and the noise power spectrum analyzer.
The USRP does not have absolute gain calibration; as a result, if you require absolute power measurements, you will have to calibrate it with a known source.

I am using the usrp2 + rfx900 with usrp2_fft.py
