Remote command:
[SENSe<Ch>:]AVERage:COUNt
[SENSe<Ch>:]AVERage[:STATe]
[SENSe<Ch>:]AVERage:CLEar
Mode
Selects one of the following averaging algorithms:
●
"Auto": Automatic selection between "Reduce Noise" and "Flatten Noise"
mode, depending on the trace format.
●
"Reduce Noise": Cumulative moving averages of the real and imaginary parts of
each measurement result, provides the most effective noise suppression for the
"Real" and "Imag" formats and for polar diagrams.
●
"Flatten Noise": Cumulative moving averages of the (linear) magnitude and phase
values, provides the most effective noise suppression for the "dB Mag", "Phase",
"Unwr. Phase", and "Lin Mag" formats.
●
"Moving Average": Simple moving averages of the real and imaginary parts of
each measurement result; similar to "Reduce Noise", but with finite history.
Changing the mode resets the average cycle.
Note: For frequency conversion measurements always "Flatten Noise" is used.

5.3 Sweep Softtool
The "Sweep" softtool allows to define the scope of the measurement in the active
channel.
This includes the sweep type (with related parameters), and the periodicity of the mea-
surement.
Access: CHANNEL – SWEEP hardkey
Background information
Refer to the following sections:
●
Chapter 4.1.4, "Sweep Control" , on page 78
●
Chapter 4.1.4.3, "Stimulus and Sweep Types" , on page 83
5.3.1 Sweep Params Tab
Allows to define the scope and timing of the measurement in the active channel.
Segmented sweeps
In "Segmented" linear frequency sweeps, the sweep parameters can be set independ-
ently for each segment. See
Chapter 5.3.2.2, "Define Segments Dialog" , on page 248.
