Hi Lee,
If you want to disable the data transmission of the Simulink block, there are two ways:
1. Go to the block's configuration dialog and set the number of inputs to 0, this will remove the DATA_IN1 and DATA_IN2 ports.
2. Go to the ADI IIO scope and set the 'DDS Mode' to 'Disabled'.
Then, to read data over the air just change the RX_LO_FREQ of the Simulink block to the frequency of the signal that you want to capture over the air and run the simulation. If you need a specific sampling rate or a specific bandwidth just change the RX_SAMPLING_FREQ and RX_RF_BANDWITH inputs of the Simulink block to match your desired settings.
Since the first method does not work for you, you can try the second method.
