Channel-Frequency Operating Mode - Promax -8 SE Manual

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) indicates 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.
