Get the actual sent Message / Information Signal using NI USRP 2920

[jndrk]

Hey guys, 

I'm using two NI 2920 connected with each other. One is TX, the other RX. I have built a simple TX to transfer an array with ones. Next, i want to measure the exact frequency of the transmitted signal. But exactly this signal i need first. Can anybody help me to get this transmitted message/information signal? I attached my TX.

Thanks!

Hello jndrk,

in the help of the niUSRP Write Tx Data you can see, that this VI always works with complex values.

http://zone.ni.com/reference/en-XX/help/373380F-01/usrpviref/niusrp_write_tx_data_poly/#niUSRPWriteT...)

In your VI you gave this VI a double value. you can try to change that. So you can send a one as a complex magnitude.

I also would recommend you to check out the expamle niUSRP EX Tx Continous Async which is shipped with LabVIEW.

With best regards
