NI USRP 2945 USING SCRIPT GENERATION

[Zarrar]

Hi everyone,

                        I want to generate barker encoded signal from nI URSP 2945 Device. I have USRP and sample projects but I do not know How to fetch I/Q components in to generate in script mode. Kindly provide help how I can generate Offtime and carrier signal or fetch Custom I/Q components in USRP.

Hi Zarrar,

I've found an article that discusses using IQ data for USRP applications. Though it is not specific to Barker Encoded signals, does the code provided help you fetch the IQ data specific to your application?

How Do I Create a Chirp Signal Using IQ Data for USRP or RF Applications?

Let me know if this does not help you fetch the IQ data for your system and let me know how I can help going forward.

Regards,

Finch Train

Hi,

You cannot generate any signal with the USRP-2945 because you have only 4 receiver with 80MHz bandwidth inside.
