Setting the Distance and Units
Distance to Display on the Trace (start, stop)
The trace can display the entire length (distance) of
the cable system you are measuring or a smaller por-
tion of the length for better detail.
If you suspect that there might be a fault at a known
distance along a cable, you can set the display to show
only that area by using the start and stop points.
Think of this as zooming in on a section of the cable.
You can set both the start point (where to begin the
trace display) and the stop point (where to end the
trace display).
Note:
You cannot set the stop point to a value
that is greater than the maximum distance you are
measuring. For example, if you have selected a data
point option, frequency span, and V
p
that results in a
maximum distance of 100 feet, you cannot set a stop
point to a value greater than 100 feet.
Follow the numbered steps in Figure 25, page 64 to set
the start distance and the stop distance. For an
antenna lead, you will typically set the start distance
at 0, and the stop distance at a few feet or meters
greater than the tower height.
Follow the numbered steps in Figure 26, page 65 to set
the distance units.
