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 (the
measurement is calibrated only for analogue channels; for digital channels refer to the
note at the end of the section).
To access
operation you should press the SCAN
[11] key. At first, the field channel (C44
in the figure) will appear shaded, indicating that is
selected and modifiable. Next to the channel, it
appears the frequency (655.25 MHz in the figure)
and the level (65 dBµV in the figure) of the
channel where the marker is pointing.
The marker is moved by using the
rotary knob [9].
To change
represented on the screen), first select it by
pressing the rotary knob until you see the "sp"
shade (at the middle bottom of the screen). Then
turn the rotary knob [9]. If you rotate clockwise
the span will increase and if you rotate
anti-clockwise it will decrease. Span
can acquire the following values: 10,
30, 100, 300 MHz and full span.
When pressing again on the rotary knob [9]
the field level of reference will be selected. It is the
maximum level of the vertical axis of the chart. By
turning the rotary knob [9] clockwise it will increase and if
you turn anti-clockwise it will decrease.
