Tx channel switching methods?


What is the best way to switch between Tx on the same board, such that only one Tx is active at a time and switch at regular intervals.

  1. Power down TX ch A or B completely, If yes then which registers should I configure?
  2. Only reduce the Gain of the channel not required to minimum so that there is no signal being output?

What are the pros and cons of the above. I am looking for a method that can give me minimum switching time.
