Proper calibration procedure when changing RF PLL on AD9371

I'm using the AD9371 and I'm making large (>100MHz) changes to the LO frequency.  I see in UG-992, under "RF PLL FREQUENCY CHANGE PROCEDURE" that I should "rerun the initialization calibrations" after making such a step change.  But in the TES software, when I log the API commands, I see that it does not do that.  It skips re-running initialization.  Is there a reason for omitting the rerun of the init cals?  (i.e. tracking cal will make up the difference eventually?).  Or should I make sure to do a rerun of init in my system when I make large RF PLL changes?  

Thanks,

- Jon

    Yes. The recommended way is following the UG for RFPLL frequency change procedure for achieving…
