Activity Search
If the
Activity
button is engaged, this will put the receiver into the
Activity
search
mode:
In this mode, the wide-band display does not show a contiguous spectrum, but
rather “hits” on discreet frequency channels. In other words, the receiver will
operate like a conventional scanner.
To prepare for the activity search, you need to first set the
Start
and
End
frequencies of the range, and the
Step
size:
The step size and the starting frequency must be determined so that they fall
on the actual channel frequencies inside the searched band. Start and End
frequencies must be within the currently selected range.
The next value to set up is the
Threshold
. The threshold can be set using the
drop-down or by keying in a value preceded by a minus, or the 'threshold line'
can be dragged with the mouse to set a value.
When started, the activity search will look for signals that exceed this threshold
value. In the activity graph, these signals will appear as highlighted peaks,
crossing the horizontal line that represents the predefined threshold.
