Video Bandwidth (Video BW)
Video BW is a smoothing operation that is performed after measurement data
is acquired. The trace data is effectively smoothed so that the average power
level of the displayed noise is the same, but the peaks and valleys of adjacent
data points are smoothed together. More smoothing occurs as the Video BW is
set lower. However, as the Video BW is narrowed, the sweep speed becomes
slower.
How to set VBW
— Press
BW 2
.
— Then
Video BW
— Then choose from the following:
—
Auto
Couples Video BW to the ResBW in a 1-to-1 ratio.
—
Man
Enter a Video BW value using the numeric keypad, the
arrows, or the rotary knob. Then press a multiplier if necessary or
press
Enter
. Setting VBW higher than RBW may smooth the trace.
.
The current Video BW setting is shown at the bottom of the screen.
# VBW x.xx XHz
(#) means manual setting.
When the Res BW/Video BW ratio exceeds 10,000, a
Meas UNCAL
warning
may appear to indicate that the Video BW filter has reached the maximum
capacity for averaging.
Sweep Type
In SA mode, the FieldFox uses two sweep types to process inputs signals. The
sweep type that is currently being used (
FFT
or
Step
) is displayed in the
lower-left corner of the FieldFox screen.
