What You Need to Know About Setting the Frequency
Span and Max Distance
Note: Changing the frequency span or the max
distance will automatically turn calibration off.
Always set the frequency span or max distance
before
calibrating the unit.
The
maximum distance
you can measure is deter-
mined by the
frequency span
, the
velocity of propaga-
tion
of the cable (V
p
), and the number of
data points
to
measure (238, 475, or 949). These factors are discussed
in the following paragraphs.
Max Distance
When you specify a frequency span,
the Site Analyzer calculates the maximum measurable
distance. If you know the maximum distance you want
to measure, you can enter it instead of the frequency
