Trouble with received signal bandwidth using ADRV9371

I am transmitting 5MHz signal using ADRV9371 and using loopback I am able to see the received signal at iio oscilloscope. But the received signal is always twice the BW of the signal transmitted.

I am using the GUI.

What could be the possible reason and how it can be corrected?

Have you checked the Tx signal in a spectrum analyzer ?

How can I change the sampling rate of transmit and receive chain in adrv9371?

I realized the change in the BW of the signal is because of the different sampling rate of transmit and receive chain.
