The Band Scope feature lets you have the scanner provide a visual representation
of radio activity in a frequency band. The screen is arranged with the frequencies
increasing in value from left-to-right, and a signal strength meter for signals. Band
Scope Mode searches a frequency range and displays the signal level in real time.
You can set the center frequency and span of the frequency range. In Hold Mode,
you can monitor the displayed frequency.
The scanner rapidly sweeps between the endpoints of the selected frequency range
and updates each bar segment with the relative signal strength in each pass. You
can use the band scope in normal mode (the bars are all updated with the most
recent signal strength) or ‘Max Hold Mode’ (the bars update only if there is a stronger
signal than one previously stored for the current position).
This feature allows you to get a “picture” of spectrum activity across the selected
range, identify intermittently active frequencies, check antenna performance, check
coax quality, verify coverage areas, and identify interference.
USING BAND SCOPE MODE
To start Band Scope mode Hold on any channel and press Func then 3(Sr 3) to start
Band Scope mode at the frequency you held at. Band Scope mode is assigned to
this Search Key (3) by default.
Search Mode ‘SRCH’ shows in the display and the scanner searches and displays
the signals of the frequency range in real time. The frequency range is shown in
32 bars determined by the center frequency and span. While searching, the center
frequency icon and the bar which shows the current frequency blink. The scanner
starts from the lowest frequency of the frequency range and searches to the highest
frequency of the frequency range. If the scanner finds a transmission, the scanner
displays the strongest and most current signal level in the bar for each frequency in
the range.
Max Hold Search Mode ‘MAX’ shows in the display and will freeze the signal
strength bars at their strongest signals.
