Channel Scanner Mode (Option 27)
The Channel Scanner option provides the choice of a bar graph or a text display showing
the amplitude of selected channels for a given air interface standard. The interface settings
can be manually entered if none of the available air interface standards meet the measure
-
ment need.
To select Channel Scanner mode, press the MODE key and use the up and down arrows to
highlight
Channel Scanner and press ENTER.
FREQ/DIST The operating frequency range for Channel Scanner mode can either be set man

Standard list, all frequency related parameters are automatically set to the appro
-
priate values for that particular standard.
