Sets the transmit powers and settling times of each antenna
port. Note that setting a power level to 0 will cause the
corresponding global power level to be used. Port numbers range
from 1-255; power levels range from 0-65535; settling time ranges
from 0-65535.
- list (array< array< Int16 >[]()[] >[]()[])
- an 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}}
