By pressing the rotary selector [9]
again, you can change the reference level,
in other words, on turning the rotary
selector [9] the graph is displaced vertically.
To modify the tuned channel, press the rotary
selector [9] again, the channel field will be activated
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).
IMPORTANT
In the SCAN operating mode, all channels are considered as analogue, as a
consequence digital channels power must be measured always from the
CHANNEL-FREQUENCY operating mode.
4.2.2.1 SCAN mode configuration
In the SCAN operating mode,
pressing the CONFIG key [14] will
access the configuration menu for this
mode.
This menu permits to change two
parameters: THRESHOLD and REFERENCE
LINE. To accede 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.
