ad9361 calibration time

Hi,

 

I have an application that uses libiio to configure an fmcomms3 board.  When configuring for sample rates < 1Msps, the calibration takes a long time (~6 seconds), and I have observed it time out once.  For sample rates > 1 Msps, the calibration is very quick (~50ms).  The application loads and enables a filter corresponding to the requested sample rate (one for <1Msps, and another for >1Msps).  Why does the calibration take longer for the lower sample rate?  Is there a way to speed it up?
