I have a doubt regarding ad9361 lo configuration. while configuring lo frequency ,should i stop pumping data in to tx interface and Rx port ? Is any condition in AD 9361 while configuring LO
You can directly change the LO frequency while sending the data using below API:
Hi srimoyi , thanks for ur reply. I am facing one issue , when i tried to switch from one frequency to another frequency using no os driver, some times LO is not configured . I observed no calib time outs, but when i read back the lo freq using ad9361_get_rx_lo_freq command i didn't get tuned frequency value.
Could u please help me regarding this. what to debug and how to move further?
What is the frequency step by which you are changing the LO frequency?
After switching to the new frequency, when you readback, are you seeing the previous frequency value? What are the frequencies in which you are seeing this issue? Are you seeing the issue at those particular frequencies everytime?
We tried changing from 162 MHz to 162.3 MHz or 162.8MHz , Not every time we faced this issue. when ever it doesnt work it is reading 0 value (freq value). Not to particular to 162 ,it is occuring in other frequencies also
Are you seeing a frequency change at TX output in spectrum analyzer?
What is the lock detect status?
