Gets the transmit powers and settling time of each antenna port.
Declaration Syntax Return Valuean array of 4-element arrays of integers interpreted as
(tx port, read power in centidBm, write power in centidBm,
settling time in microseconds) tuples. An example with two
antenna ports, read power levels of 30 dBm, write power levels of
25 dBm, and 500us settling times:
{{1, 3000, 2500, 500}, {2, 3000, 2500, 500}}
