I am using 2 AD9361 devices in the following configuration:
1. Both devices are connected to FPGA
2. External LO is used (1 LO connected to both AD9361 devices)
A signal that is generated by external signal generator (CW signal at 2.4 GHz) and is received by these 2 AD9361 devices.
The signal that is being sent from AD9361 devices to FPGA.
Sometimes 1 of 2 AD9361 devices does not provide a valid Rx signal to FPGA but a noise at high values that saturate the AD9361 Rx channels.
The issue happens from time to time and mostly on second AD9361 device.
What can be the reason for this issue?
