[SENSe<Sensor>:][POWer:][AVG:]SMOothing:STATe <state>
Enables or disables the smoothing filter, a steep-edge digital lowpass filter. If you can-
not adjust the aperture time exactly to the modulation period, the filter reduces result
fluctuations caused by modulation.
Parameters:
<state> ON | OFF
*RST: OFF
Example:
SMO:STAT OFF
Manual operation: See "Smoothing" on page 45

Burst Average Measurement
The Burst Average mode is used to measure the average power of bursts. The time
interval in which the average power is measured starts when the power exceeds the
trigger level and stops when the trigger logic detects the end of the pulse.
Fig. 9-2 shows a graphical representation of a burst average measurement and the
meaning of the parameters that can be configured.

Figure 9-2: Burst average measurement parameters
To prevent power drops due to modulation from being erroneously interpreted as the
end of a pulse, you must define the dropout tolerance. This is a time interval in which
the pulse end is only recognized if the signal level no longer exceeds the trigger level.
Triggering a burst average measurement
In the burst average mode, only internal trigger events from the signal are evaluated,
irrespective of the setting of the TRIGger:SOURce parameter. The TRIGger:DELay
parameter is also ignored, so that the measurement interval begins exactly when the
signal exceeds the trigger level.
Defining a time interval for the measurement
Time intervals that are to be excluded from the measurement can be set at the begin-
ning and at the end of the measurement interval with the commands
