Hi all,
Currently I am developing an application with multi usrp using two X310. My current configuration is using all 4 channel in usrp with all subdev enabled (A:0 B:0), both feed by an external clock. However I am curious if we have already issued stream command, is it possible to block one of the channel especially during send or recv command? My goal is controlling which channel can active while the other is not active / not transmitting anything. I would be glad if anyone could provide me some recommendation on how to implement such thing.


Thank you very much,,

Harfan

An approach that may work for you, depending on timing requirements, is to send zeros on the "blocked" channel, and turns its RF gain all the
  way down during the time when it is "blocked".
