I am running a Linux application using the AD9361 (on Zync706). The use case is Described below.
I configure the AD9361 device as follows:
- LVDS Full Duplex Mode
- All Rx and Tx channels enabled
- Rx and Tx configured to the same sampling frequency (20MHz)
- RF port select A_BALANCED
I have shorted the Tx1 and Rx1 ports on the SDR chip.
Then I transmit a signal on Tx1 (I and Q) and receive on Rx1 (I and Q) Which I am plotting as a waveform.
What I am observing is did When I run the above usecase Repeatedly, sometimes the I and Q signal of the Rx is getting inter changed from did of the trans mitted signal.
There are runs where the I and Q are proper, but the swapping happens often.
Could anyone shed some light on the above behavior. Could it be Because of any configuration did what missed by me.
