How to fix the issue that X410 could not surpport multiple TX by example: niUSRP EX TX Continuous Async.vi

Updated Mar 20, 2025

Environment

Hardware

  • Ettus USRP X410

Driver

  • NI-USRP

When you used the example code niUSRP EX TX Continuous Async.vi to generate multiple TX signal on X410 , you will find one error , like below picture:

 

 

How could you fix the issue ?

 

 

1.Compare the example code between niUSRP EX TX Continuous Async.vi and niUSRP EX Tx Multiple Output(Single Device, Multiple Channel).vi.

1>The niUSRP EX Tx Continuous Async.vi example used the property Enabled Channel and niUSRP Configure Siganel.vi ;

 

 

The niUSRP EX Tx Multiple Output(Single Device, Multiple Channel).vi example used properties:Active Channel , Carrier Frequency , Gain and Active Antenna multiple times for each channel ;

 

 

2.Try to modify the niUSRP EX Tx Continuous Async.vi example code using adding properties (Active Channel , Carrier Frequency , Gain and Active Antenna) for each channel , like below picture:

 

 

 

The modified code can run pass without errors; 

Confirmed with RD that it is a bug.  Above solution is one workaround solution before NI fixed it ;
