Average Mode
Defines the mode with which the trace is averaged over several sweeps.
This setting is generally applicable if trace mode "Average" is selected.
For FFT sweeps, the setting also affects the VBW (regardless of whether the trace is
averaged).
(See also "Video bandwidth (VBW)" on page 166).
How many sweeps are averaged is defined by the "Sweep/Average Count"
on page 474.
For details see "How trace data is averaged - the averaging mode" on page 584.
"Linear"
The power level values are converted into linear units before averag-
ing. After the averaging, the data is converted back into its original
unit.
"Logarithmic" For logarithmic scaling, the values are averaged in dBm. For linear
scaling, the behavior is the same as with linear averaging.
"Power" Activates linear power averaging.
The power level values are converted into unit Watt before averaging.
After the averaging, the data is converted back into its original unit.
Use this mode to average power values in Volts or Amperes correctly.
In particular, for small VBW values (smaller than the RBW), use
power averaging mode for correct power measurements in FFT
sweep mode.
Remote command:
[SENSe:]AVERage<n>:TYPE

Average Count
Determines the number of averaging or maximum search procedures If the trace
modes "Average", "Max Hold" or "Min Hold" are set.
In continuous sweep mode, if sweep count = 0 (default), averaging is performed over
10 sweeps. For sweep count =1, no averaging, Max Hold or Min Hold operations are
performed.

[SENSe:]AVERage<n>:COUNt
