niUSRP error

[rhPro]

Hi everyone, i find difficulty when dealing with my usrp n2922 using sbx daughterboard. In error out box it's written like below

___________________________________________________________________________
niUSRP Configure Signal.vi<ERR>A runtime or configuration error occurred.
Code: 972
Details: AssertionError: assertion failed:
   is not a valid sbx tx antenna name.
  possible values are: [TX/RX, CAL].

and in status code it's written -1074118627
___________________________________________________________________________

Do you have any idea about this? I have set the active antenna correctly by the way.
Anyone knows what's wrong? And what the code "-1074118627" really mean?

Thank you for giving solutions 🙂

I can't think of anything off the top of my head. Could you post a screenshot of the relevant parts of the front panel/block diagram?

here i attach my program. i use usrp n2922 and n210. but in my program the receiver receive nothing

Hey rhPro,

Has this device worked in the past? Does it work when you try any other code? I suggest trying one of the NI USRP example programs (usually found in C:\Program Files (x86)\National Instruments\LabVIEW\examples\instr\niUSRP). This will help us to know whether it's a more general issue with the device or an issue specific to your code.

[rhPro]

yes, it had. im'sorry but what do you mean with another code? 

and why there is no example how to synchronize Rx and Tx when we use 2 USRP (1 as Tx, 1 as Rx)?

Hey rhPro,

The error message that you described could be due to an issue with your LabVIEW application or a hardware issue with the USRP. By trying another piece of USRP code, we can determine whether the hardware is functioning properly.  I suggest trying one of the simple example programs found in C:\Program Files (x86)\National Instruments\LabVIEW\examples\instr\niUSRP. If it runs normally we can eliminate a hardware fault and focus on your code.

I suggest looking at these pages for references about synchronizing RX and TX between two devices:
