SCAN mode configuration

In the SCAN operating mode, pressing the
CONFIG key [14] will access the configuration menu
for this mode.
This menu permits
parameters: THRESHOLD, REFERENCE LINE and
POWER MEASUREMENT. To access to any of
them, turn the rotary selector [9] until it appears
shaded and next press the selector, then the value of the parameter will appear shaded
and turning the selector you will be able to modify its value. Finally, to validate the new
value, press the rotary selector [9] again.
a) THRESHOLD
It defines the minimum level to show channel on the display (OFF or between 21
and 120 dBµV). If the threshold is deactivated (OFF), on the SCAN representation
will appear all the active channels of the channel plan with a level higher than
20 dBµV. Otherwise, if we define a level for the THRESHOLD parameter, channels
with a level lower than the threshold value will not be displayed.
b) REFERENCE LINE
It permits to activate or to deactivate (OFF) a reference line on the SCAN graph
(between 21 and 120 dBµV). This reference line allows to establish judgements of
channel level acceptance just with a glance at the SCAN screen.
c) POWER MEASUREMENT
It allows to define if the measurement of the power is carried out on the channel
bandwidth (CHAN) indicated by the MARKER or over the full band between 5 and
863 MHz (∑PWR).
To leave the SCAN operating mode configuration menu, just press the key of the
operating mode you wish to access.
