SCOPE OPERATION
Spectrum scope screen
The spectrum scope enables you to display the
activity on the selected band, as well as the
relative strengths of various signals in that band.
The transceiver has two spectrum scope modes,
the Center mode and the Fixed mode. You can
also turn the Waterfall display ON or OFF.
In addition, you can select the Mini scope to
display the scope in a smaller size on the screen.
• Center mode screen
• Fixed mode screen
D
Marker
The Marker displays the operating frequency in
the SPECTRUM SCOPE screen.
• About RX Marker
In the Fixed mode, the RX Marker displays the
operating frequency within a specified frequency
range. So, the transceiver always displays the RX
marker in the Scope screen.
In the Center mode, the operating frequency stays in
the center of the screen. Thus, the transceiver does
not display the RX Marker.
LWhen the Hold function is ON, the RX Marker is
displayed to indicate the operating frequency’s
location.
DUsing the Spectrum Scope
Display the SPECTRUM SCOPE screen.
