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:
3.85 MHz – min., 8.25 MHz – max.
Example 2:
5.50 MHz – max., 2.75MHz – 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:
28.4 Ohm – min., 88.4 Ohm – max.
Example 2:
90.0 Ohm – max, 61.3 Ohm – min.
5. Calculate the square root of the
product of these two values.
Example 1:
square root of (28.4
×
88.4) =
50.1 Ohm
Example 2:
square root of (90.0
×
61.3) =
74.3 Ohm
