Can someone please answer my questions below?

 

I new to this and would like to know what are the max # of frequencies that a ABPA can broadcast simultaneously at one time? I don't own one, but I would like to know more about how it operates as far as the # of frequencies it can put out at one time, Does it broadcast frequencies in a "group" one group after another in one session, or an infinite number of them all at the same time in one session?

 

Thank You,
