Average Type

In SA Mode, there are four different processes in which Averaging is performed:
— Average Traces – Learn more in
— Detection Method Averaging – Learn more in
— Noise Marker Averaging - Learn more in
— Video BW filtering (for non-Zero Span measurements) - Learn more in
There are three types of mathematical averaging that can be performed – Log,
Linear, or Voltage (see
types and it is used for all of the above averaging processes.
How to set Average Type
— Press Meas Setup 4 then

—Auto - The FieldFox chooses the most appropriate type of averaging
for the current settings. When Detection Method is set to Average, a
Noise Marker is present, or a Channel measurement is active, then
Power Average is ALWAYS selected. Otherwise, Log Average is
selected.
—Log Averaging – Best for displaying Trace Averaging. LgAv is shown on
the left side of the FieldFox screen when selected.
—Power (Linear) Averaging – Best for measuring true power levels. Used
in Detection Average and Noise Marker Average. Mathematically,
trace noise is 2.5 dB higher than when using Log Average. PAvg is
shown on the left side of the FieldFox screen when selected.
—Voltage
