"2"
Lower sampling rate
Recommended to avoid measurement errors caused due to aliasing
effects. However, this setting extends the measurement time.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:SAMPling
Smoothing
Available for continuous average measurements.
Enables or disables the smoothing filter, a steep-edge digital lowpass filter. The filter
reduces result fluctuations caused by modulation.
"Off"
If the modulation frequency is known, set the
time exactly to
an integer multiple of the modulation period and disable smoothing.
Otherwise, the modulation can have a considerable influence, even if
the sampling window is much larger than the modulation period.
300 to 3000 periods are required to obtain the same effect as with
smoothing enabled. The sampling values are considered equivalent
and are averaged in a sampling window, which yields an integrating
behavior of the measuring instrument.
"On"
If the modulation period varies or is not precisely known, enable
smoothing.
The selected sampling window has to be 5 to 9 times larger than the
modulation period so that the fluctuations caused by modulation are
sufficiently reduced. The sampling values are subjected to weighting
(raised-von-Hann window), which corresponds to video filtering.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>][:POWer][:AVG]:
SMOothing[:STATe]
Dropout Tolerance
Available for burst average measurements.
Detects the falling edge of a burst. If the power keeps low for at least the set time, the
end of the burst is assumed. Modulation-specific power drops that are shorter than the
set value are ignored.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>][:POWer]:BURSt:
DTOLerance
Exclude from Start, Exclude from End
Available for burst average measurements.
Sets the time interval at the beginning or end of bursts that is excluded from the mea-
surement. Thus, signal overshoots are omitted.
Remote command:
CALCulate<Measurement>[:CHANnel<Channel>]:BURSt:TIMing:EXCLude:
STARt
CALCulate<Measurement>[:CHANnel<Channel>]:BURSt:TIMing:EXCLude:
