Hi,


In latest API release, there are some limitations regarding Dynamic Profile Switching such as:


    

  • Limited to LTE
    • 

  • Operates simultaneously on all configured channels and cannot operate on any channels individually
    • 

  • Adrv9001 will either operate in Frequency Hopping mode or DPS mode never both*
    • 



As far as I know this functionality is under development. Can you answer the following questions both for current and future releases(plans).


Are these limitations operative on only PROFILE switch? By PROFILE, I mean adi_adrv9001_Init_t structure.


Is it possible to switch only PFIR coefficients instead of whole PROFILE? If so, are those limitations still in force?




My main question is:


Is it possible to Program a new(or predefined at initialization stage) 128-tap PFIR when:


    

  1.  Operating in Frequency Hopping mode
    2. 

  2.  Arbitrary Sampling Rate
    3. 

  3.  Individually for a channel
    4. 



Finally it is declared that profile switching time is 50us. Are you working on it to improve switching time? What could be the best scenario?


Best Regards
