ADRV9009 OBS settings : ADI IIO Oscilloscope GUI

HI ,

For the setup ZCU102+ADRV9009, we are trying to validate the ORX path by looping TX & ORx path  using ADI-IIO Oscilloscope GUI.. 

Unable to get the waveform. Can anyone help with the necessary parameter settings to be made in the GUI to obtain the waveforms.

Thanks in advance.
