Hi EZ support,


1 pair AD-FMCOMMS3 are connected with two ZC706,  one is transmitter and one is receiver. For quick test, they removed the crystal on board and replaced with external clock from signal generator, i.e., two boards share the same clock so there should be NO timing issue.


They try a TDD mode with slot = 26ms, and the transmitted data is the same for every slot,   that means if transmitter sends same repeated data, the receiver side should receive NO phase shifted data.


But they see the received data is with some phase shift if they use their own AD9361 config script.


There is NO phase drift is they use the provided IIO scope to config AD9361, that means their config sequence is not correct.


They need help on this and could you provide a sample configuration program?  or provide the registers configuration sequence ?



Thank you.
