What does the parameter mean in IIO System Object?

Hello Everyone, I found that IIO System Object could be a very convenient tool when developing on fmcomms2. However, some parameters in it really confused me.  There is a enclosed settings window from one input signal module.My questions are as follows:

  1. The width of data interface of AD9361 should be 12 rather than 16, so why here the maximal value is 32768(2^15) rather than 2^11?
  2. Here the frequency is setting to 100 Hz, so what the real frequency offset should be relative to LO frequency? 
  3. How do you set sample time and samples per frame?  

Could anyone provide some help to me?
