I understood from the GUI interface of ZCU111 that the settings of cross bar and mixer mode settings should be the following :
My question is , What exactly is Real Single Mode, Real Dual Mode, IQ Single Mode , IQ Dual Mode. Can someone explain these terms ?

Real Single Mode : Only one band in incoming signal. simplest use case.
Real Dual Mode: there are two bands in the incoming signal, ADC samples the signal and there are two Mixers behind to shift the incoming signal to the expected frequency point.
IQ Single Mode: complex signal input to two separate ADC. One for sampling I signal and the other for sampling Q signal. IQ signal then is sent to one mixer that is behind two ADC.
IQ Dual Mode: complex signal includes two bands. two ADC enable to sample I and Q separately and then sent I signal and Q signal respectively to two mixers.

Hi, thanks for your reply. Just want to clarify on IQ Single Band . "It should be used when the input signal is complex and single band right ?"
