Hi,
I want to know the true noise power(in dbm) of the usrp n210.And i'm using the sbx and lp0964 antenna.
Do someone have the data?
Thanks.

Performance data includes noise figure.
Not sure what you mean by "true noise power". But noise figure tells you how much extra noise is added by the device itself.
A 3dB noise figure is equivalent to a PSD of -174dBm/Hz.
A 5dB noise figure is equivalent to a PSD of -172dBm/Hz.
And so on.
