3. Changing the display range and
performing additional scans, find a
frequency where
R
(resistance) reaches
its maximum, and another frequency
with minimum. At these points,
X
(reactance) will cross the zero line.
Example 1:
30.00 MHz – min., 60.00 MHz – max.
Example 2:
41.00 MHz – max., 88.40 MHz – min.
4. Switch to the
Data at cursor
screen
by pressing the
(Data) key and
find values of
R
at previously found
frequencies.
Example 1:
33.0 Ohm – min., 78.5 Ohm – max.
Example 2:
99.2 Ohm – max, 53.4 Ohm – min.
5. Calculate the square root of the
product of these two values.
Example 1:
square root of (33.0
×
78.5) =
50.7 Ohm
Example 2:
square root of (99.2
×
53.4) =
72.8 Ohm

The Tools menu (see page 26) contains several automated tools for coaxial line
calculations.
