USRP B210 local oscillator error

[PHDHA]

Hi;

I'm working under detecting NB IOT signal at center frequency 900 MHz, so how can i select the sample rate and the center frequency of USRP B210 to reduce the oscillator error. Taking account that NB IOT sends OFDM symbol wich are spacing by 15 KHz, so i should select the good parameters to have the USRP's oscillator error less than 15 KHz.

 I'm so gratefull if you can help me.

Best Regards

Hi PHDHA,

I am not sure how the selection of the sample rate would influence the frequency offset (oscillator error) between oscillators.

To reduce the frequency offset, you would typically supply a 10 MHz reference signal. The USRP b210 has a designated port for the 10 MHz reference signal.

Best regards
