2.344 Hz is a fairly small number if your sample rate in in the hundreds of kHz. It is likely an artifact of the size of the FFT used for determining the frequency offset. Your radio is probably just fine.

Subject: [USRP-users] USRP - N210 Frequency Offset Calibration
I am using one USRP N210 with daughter boards LFTX and LFRX (operating frequency range is 30 Mhz) using Simulink model. I used the Simulink model from Mathworks for Frequency offset calibration and it showed -2.344 Hz
I compensated this value at SDRU_Rx , but it still shows the same freq offset value. Since I am using the same USRP for transmitting and receiving with the same local oscillator , why it shows this offset value.
Any suggestion please !
Mit freundlichen Grüßen / Best regards
