In umx_sample.cpp, SoraURadioSetSampleRate(TARGET_RADIO, 40) means that the sampling rate is 40MHz.But when I set the sanpling rate to 20,I can't see any changes of the receiving I/Q data.So,I doubt that the function is not useful.Maybe I don't know how to use this function or the sampling rate of radio front end is not changed.Can you answer my question?
thank you very much!

Hello,Sen Xiang,thank you for your reply.
My firmware is USRP and the daughterboard is XCVR2450,whether this firmware can support sanmple rate configuration or not .

No. You cannot change the sampling rate on this daughterboard.
You may resample in software.

Thank you for your reply!
Can you tell me the sample rate of DAC chip in USRP? I guess it is the same to ADC sample rate?
