[Discuss-gnuradio] How to change a master clock rate on USRP B210

[raf raf]

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.
