Assistance Needed with Signal Reception Using USRP N210 in GNU Radio Companion

Dear GNU Radio Community,

I am currently working on a project that involves receiving a signal from an external signal generator source using the USRP N210 device. The carrier signal is at 1 GHz, and the message signal is at 1 kHz. To analyze the frequency spectrum, I am using the USRP source block and the QT GUI frequency sink block in GNU Radio Companion. However, I am not achieving the desired signal reception.

I have a few questions regarding the setup:

• In the RF options, what value should I set for the channel center frequency to properly receive the signal?
• Are there any specific example flowgraphs in GNU Radio Companion that I can reference to test the signal reception effectively?
• Could you please outline any additional requirements or configurations necessary for successful signal reception using the USRP N210 device?

I would greatly appreciate any guidance or suggestions you can provide to help me resolve this issue.

Thank you for your assistance.

Best regards,

Muhammad Anas
