Thank you,
In GRC, I changed Clock Rate (Hz) by giving a value of 28e6 and it works now.

      "device args" parameter is not in the UHD USRP
        source/sink block?There is only 'Device addr'

      
      

      
    
    Sorry, I meant Device Addr

                      Hello
                            All Gnu Radio user, 
                      
                          
                      To
                            use a 2 TX, I want to change a clock rate to
                            an accepted one, under 30.72 MHz. I use the
                            API with uhd_usrp_probe and it works only
                            for this command. Can you give me the idea
                            or python code to use this argument
                            parameter with a python flowgraph?
                      
                          
                       --args="master_clock_rate=28"
                      
                          
                      Thanks.

              In GRC, where it has a "device args" parameter, that's
              wher this master_clock_rate=28e6  should go.  I assume you
              meant 28e6, rather than 28.

                Everything is in Hz, and there's no way the B200 can go
              down to a clock rate of 28Hz.
