How good is the time, frequency, and phase match after calibration?
The frequency match is unaffected by the calibration. The two devices should be within a few Hz of each other, worst case, when using internal LO. When using external LO the frequency will be exact.
I'm still trying to optimize the calibration routine, as well as account for the balun skew, but I expect that the phase across the four Rx or Tx paths will be within 3 degrees.
My purpose is to create a MIMO receiver using the Zed + AD-FMCOMMS3-EBZ board+AD9361,and use vivado to write to design the Verilog project,when you build your system ,how to design your Synchronization module with AD9361,what i think Synchronization module consist of Timing_Symcronization part,Phase_Tracking part,CFO_Correction part,how is your design goes with that?
