Comment
Default = min
Default = min
Not needed if not controlling LNA power
Default = min
Can increase to non-zero if performance
degradation is observed and the channel
is transmitting for some time before the
start of the actual frame
(Forced to be 0 currently by ADRV9001)
Default = min
Can increase if performance degradation is
observed and the channel is transmitting
for some time after the end of the actual
frame
(Forced to be 0 currently by ADRV9001)
Default = max
Can decrease if not all data sent through
interface needs to be transmitted.
