[Discuss-gnuradio] TX/RX caliberation utilities provided in UHD

[Gayathri Ramasubramanian]

Hi

I would be grateful if anyone could explain more about the TX/RX calibration
utilities provided by UHD:
        uhd_cal_rx_iq_balance:      uhd_cal_tx_dc_offset:        
uhd_cal_tx_iq_balance: 

 a) I found them installed in one of the UHD directories. Not sure now, but
wanted to know if the same version can be used on SBX and WBX
daughterboards. what changes in output should Ii expect to see.
How can I keep a note of it. are there any specific tests I can use.

b) What do these utilities exactly do. 
c) do they write into the fw of the motherboard. if so, how can i remove the
calibration if required.
d) what happens if a serial number is not present in the WBX boards. 
e) application notes says: it creates a CSV file. how will it be stored and
retrieved.

I am trying to use these utilities but before i do I just wanted to clear my
doubts.

Any help will be appreciated.

Thanks
Gayathri
