I would like to know the exact meaning of the result of the uhd_cal_tx_dc_offset for the USRP i am using. what is the significance of this.
does it mean, the peak at a certain frequency i am getting for range profile is not the true frequency?
kindly explain.

How can we compensate this offset?

For the error "Could not find block with Noc-ID", this is not a serious error: This bitstream is a custom bitstream from "Wireless Testbench" product and should be used by that product and the associated "Wireless Testbench Support Package for NI USRP Radios".
My understanding is the the tool uhd_cal_tx_dc_offset performs a calibration routine and generates these .cal files.
