Hi Engineers:

     I'm  doing  a  frequency hoppoing system with AD9361 and zynq7030. The gard time of my signal is no more than 50us. So want to use fast lock mode. Here is the initial code.Can you please give tell me whether my initial operation is

correct?

set_tx_lo_freq(F1);

set_rx_lo_freq(F1);

tx_fastlock_save(F1);

rx_fastlock_save(F1);

............

set_tx_lo_freq(F8);

set_rx_lo_freq(F8);

tx_fastlock_save(F8);

rx_fastlock_save(F8);

Then when the calling time is coming,I would do the folloing operarion:

tx_fastlock_recall(F1);

rx_fastlock_recall(F1);

.............

tx_fastlock_recall(F8);

rx_fastlock_recall(F8);

Because our system is TDD and has guard time for TX to RX for AD9361, the time for this is no more than 10us. Firstly I want to racall the frequency and then I want to switch the TX and RX. So the total time is approximately about 20us+10us=30us? Hope for your reply. I don't know whether my idea is correct.Hope for your help.
