I am working with zed board+ AD-FMCOMMS3 boards.I have two such boards and I am trying to establish full duplex communication between them.I have gone through the documentation.
1. As far as I have understood the 2 Rx channels and the 2 Tx channels operate at same frequencies,is that correct?
2. If so,why then are two separate Rx and Tx channels are provided?
3. Also while experimenting with iio scope application,I found that when I was in the DAC buffer output mode and uploaded a sine waveform file,when I removed the antenna of transmitting channel the capture window displayed a sine wave.What could be the reason for this.
