In
HAM mode
, the SWR icon and the range over which the measurement is carried out are displayed at the
top of the screen.
In the center of the screen, a chart of the
SWR
values for the range is displayed.
The value of the minimum
SWR
found and the
frequency
at which this value was found are displayed at the
bottom of the screen.
Important! To the left and right of the graph are two vertical stripes. They indicate going out of range. Sometimes the
resonance of the antenna may be out of range, but very close to the beginning or end. In such cases, the analyzer will
determine the resonance beyond the limits of the ranges.
When you press the
or
keys the analyzer switches to
Free mode
with the center frequency of
measurement corresponding to the center frequency of the selected range:
You can exit the mode in the main menu by briefly pressing the
key.
Free mode.
This is a classic
SWR
measurement mode with plotting in a user-defined frequency band.
This mode is useful for survey measurement of the antenna in a wide frequency range or for measuring
the
SWR
in a very narrow predetermined area.
In
Free mode
, the following is displayed on the analyzer screen:
