TDMA (Time Division Multiple Access) Application Using USRP-2930 Devices

Hi,

While I was trying to synchronize my transmitters (each of the transmitters are USRP-2930 devices), I used the trigger vi provided by Labview. (Specifically the "niUSRP Configure Trigger.vi ")

 

Right now, I would like my devices to transmit signals at specific times, i.e, at each second precisely like 1.000, 2.000. When I tried to implement this, I have encountered an error message saying that the aforementioned vi cannot be changed during a session. Even though I can change other properties on the fly (like Center Frequency, Gain etc.), I could not change the trigger time.of the transmitters Is there any alternative way to implement this?

 

Best Regards,

Nazım

Hi @Nazim,

 

Do you mind sharing the code and the error messages? That would be a good place to start.
