REG : Receiving the Data In USRP b205mini

Hi,
I want to receive the ADC data in USRP b205mini-i module. For that I
have written the Rx streamer code using UHD API.

Actually, Rx port is connected to some signal generator of 430MHz to
470MHz. But, When i see the ADC data from streamer is not matching. Is
there is any want access the Rx LO in the USRP. When I print the Number
of Rx Lo names, it shows as 0. How to set the LO as 400MHz frequency? Is
there is any default LO frequency is set?

And I want to know the default decimation factor for this board?

Thanks,
Kavinraj.

Please look at "rx_samples_to_file.cpp" example, which shows how to
stream properly.  Set sample-rate properly, and set
  center-frequency properly.
