As you see,this is the Tx part of ad9361_sim demo.It can work normally.
When I change the Tx signal to QPSK.There is a problem.
I tried to solve the problem but failed.Have you successfully replaced the Tx signal source?
You are passing scalars in the working model and vectors in the non-working model. Try adding an Unbuffer block in the IQ data stream.
Thanks,it's work.There is no problem.
But the output has always been 0.I and Q two-way signal data is gone.Modulated signal datas are all replaced by 0.
I can not find the reason for the error after not being given the error....
Do your signals into the ad9361_tx block have identical sample times? You can easily check this by enabling sample colors: Display->Sample Time->All
