Scan Operating Mode - Promax 10 Manuel D'utilisation

4.2.2 SCAN operating mode

The SCAN operating mode shows, in a single screen, the signal level of all the
active channels in the channel plan by means of a bar-graph. In addition, the exact level
of any particular channel may be measured by simply placing the marker over it (only
analogue channels).
To access to this operating mode,
press the SCAN key [11]. The top line of the
screen will display the channel name (C44),
the tuned frequency (655.25 MHz) and the level (65
dBµV) of the channel the marker is over. The marker
can be moved by turning the rotary selector [9].
The channel is selected when it is shaded.
To change
bandwidth), press the rotary selector [9] (the
span field is activated) and then turn it. The
span is variable from the entire band ( full span ) to 10
MHz in the following steps:
10, 30, 100, 300 MHz y full span.
By pressing the rotary selector [9]
again, you can change the reference level,
in other words, on turning the rotary selecter
[9] the graph is displaced vertically.
To modify the tuned channel, press the rotary
selector [9] again, the channel field will be activited and
then turning the rotary selector you will be able to
change it.
The attached figure shows an horizontal line at
45 dBµV. This line allows to establish judgements of
channel level acceptance easily. To activate and define
this reference line see the Scan configuration menu
(section 4.2.2.1).
The SCAN operating mode also allows channels
to be programmed for use as pilots in TILT operating
mode, in the forward band (see section 4.2.5 TILT
operating mode ).
