Averages the data as appropriate for the linearly scaled
y-axis scale.
With average type set to
Voltage
, “
VAvg
” appears on the
left side of the display.
There are actually four types of averaging processes
within an N9340B. All, except VBW filtering, are affected
by this setting. They are listed as follows:
• Trace averaging
Averages signal amplitudes on a trace-to-trace basis.
(Press
Log Pwr
or
Pwr
)
• Average detector
Averages signal amplitudes during the time or frequency
interval and represents the result as a single
measurement point.
• Noise marker
Averages signal amplitudes across measurement points
to reduce variations for noisy signals.
• VBW filtering
Performs a form of averaging of video signal.
