Burst Average
The power sensor measures the average burst power of pulsed signals. The burst
average measurement is available with multipath and wideband power sensors.
No external trigger signal is required, because the power sensor detects the start and
end of the burst itself. The time interval in which the average power is measured starts
when the power exceeds the trigger level and ends when the trigger logic detects the
end of the pulse.

To prevent power drops due to modulation from being erroneously interpreted as the
end of a pulse, you must define the dropout tolerance. The dropout tolerance is a time
interval in which the pulse end is only recognized if the signal level no longer exceeds
the trigger level.
