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
“Video Bandwidth (Video BW)” on page 164
.
There are three types of mathematical averaging that can be performed – Log,
Linear, or Voltage (see
). Select ONE of these
types and it is used for all of the above averaging processes.
How to set Average Type
— Press
Meas Setup 4
then
Average Type [current setting]
— Then choose from the following:
—
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
Average Count
The Average Count setting is used mainly with the Average Trace State
described above. In this Trace State, the Average Count setting determines the
number of sweeps to average. The higher the average count, the greater the
amount of noise reduction.
When Trace (display) State is set to
Average
,
MaxHold
, or
MinHold
, the
average counter is shown in the left edge of the screen below the Average
Type.
For all three of these Trace States, when
Sweep 3
Continuous
is set to OFF,
press
Restart
to reset the sweep count to 1, perform <n> sweeps, then return
to
Hold
.
