It is not clear what the definition of Fcutoff is in the AD9361 filter wizard. The Filter Wizard wiki does explicitly define the parameter but mentions that it can be adjusted. How is Fcutoff defined? Is this a 1dB corner, 3dB? Does it correspond to the Rx single-pole TIA filter, the Rx 3rd order Baseband filter, or is it the composite response of both analog filters in cascade? 

 

Additionallly, there is a parameter below FCutoff (Analog) that is only called "RF" and has a frequency associated with it. What is this parameter? Does it mean anything?
