Our customer met one trouble for AD-FMCOMMS3-EBZ.
Why cannot show the Rx2A waveform after switching "from TX_MONITOR2 to Rx2A"?
Set Tx LO=2400MHz, and set the FPGA setting as following.
At this time, we can see the waveform RX1A and Rx2A with no problem.
Make change the RF Port Select to the TX_MONITOR2.
At this time, we can see the waveform Rx1A and the Tx_MONITOR2 with no problem also.
Make change the RF Port Select to the A_BALANCED.
At this time, we can see Rx1A waveform, but we CANNOT see Rx2A waveform.
a) Why can we not see the waveform at this time?
b) How should we fix this trouble?
Following is their connection figure.
