particular RF spectrum analyzer supports other bandwidths they can be
used. Refer to your RF spectrum analyzer Operating and Service manual
for a list of the available bandwidths.
NOTE
Do not use bandwidths greater than 3 kHz at a frequency
of 100 kHz.
Video Bandwidth
The video bandwidth entry should be specified by the following equation
for accurate noise measurements.
T
,. . _ . . , . Resolution Bandwidth
Video Bandwidth =

Sweep Time
The value of the sweep time will, more than anything else, affect the
accuracy of the measured results. The following procedure should be used
to determine reasonable sweep time values.
1.
Determine the RF analyzer's default sweep time. This can be done
by setting the RF analyzer to the parameters specified in the segment
table for the specific segment.
2.
Perform a sweep on a known signal at the default sweep time and
measure the amplitude of the signal.
3.
Divide the default RF analyzer sweep time by 2.5 and set the RF
analyzer to this new sweep time.
