I have multiple AD9361 that I need to synchronize the RF phase. I'm already doing the MCS for the baseband. That's working. I've read your documents on RF phase sync and IQ correction. My question is: If I have the system configured for FDD and TX and RX are at different frequencies, can I still do the RF calibration? Don't I need to set the frequencies to be the same to transmit/receive a signal from one chip back to another? If so, doesn't the RF phase change and invalidate the calibration once I change the frequency back to the normal operating frequencies?
