Hi Marcus, I have tried setting the tx_subdev "A:0 B:0 A:0 B:0" probably you mean only "A:0 B:0" since it produce another error saying input port already connected. I have tried another several benchmark configuration as follow: 1. ./benchmark_rate --tx_rate "1e6" --args "addr=192.168.40.2" --tx_su

Hi Marcus, Thank you for your respond, I just realize it seems somebody in the mail list has the same exact problem with me, but i check noone has answered to the problem. I have tried to run ./benchmark_rate --tx_rate "1e6" --args "addr0=192.168.40.2,addr1=192.168.50.2" --channels "0,2" --ref "ext

[USRP-users] Function Set_tx_antenna or set_rx_antenna

2018-05-18 Thread harfan ryanu via USRP-users
Hi All, I have question related to two function in UHD. There is a function to choose subdev (set_tx/rx_subdev_spec) and set antenna (set_tx/rx_antenna). What is the difference between these two function? If i choose for example subdev A:0, does it automatically select antenna in the RF A daughterb

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 t

[USRP-users] Reference Clock PLL failed to lock external source during daisy chain

Hi All, I am building application with two USRP X310 configuration using daisy chain. When i try to synchronize both USRP using this : usrp.ptr->set_clock_source_out(true,0); usrp.ptr->set_time_source_out(true,0); usrp.ptr->set_clock_source("external",1); usrp.ptr->set_time_source("external",1);
