Spectrum scope screen
This DSP-based spectrum scope allows you to display
the activity on the selected band, as well as the relative
strengths of various signals.
The
IC-7850
has two spectrum scope modes. One is
the Center mode, and another one is the Fixed mode.
You can also select Dual scope, Single scope, and
Waterfall display ON or OFF for your convenience.
In addition, there is a Mini scope screen to save screen
space.
NOTE:
Spurious signal waveforms may be displayed.
They are generated in the internal scope circuit and
do not indicate a transceiver malfunction.
