AD9361 RX signal inversation when gain change

Dear all,

 

we use the AD9361 @ 407Mhz for a TDD transmission. The AGC uses the full gain table as it is defined in the no-OS driver.

 

We've observed that when the gain changes from 25 to 24, the pĥase of the received signal (set as a pure carrier for this test) change from X to X+180.

 

Does someone have info on this kind of issue ?

Stéphane.
