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
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.
a)
THRESHOLD
It defines the minimum level to show channel on the display (OFF or between -20
and 20 dBm). 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
dBm. 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 20 dBm). This reference line allows to establish judgements of
channel level acceptance just with a glance at the SCAN screen.
c)
POWER MEAS
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 1 and
50 MHz (∑MHz).
To leave the SCAN operating mode configuration menu, just press the key of the
operating mode you wish to access.
4.2.3 CHANNEL-FREQUENCY operating mode
The CHANNEL-FREQUENCY operating mode provides the following measurements:
Digital PLC channels:
To access to this mode of operation, press the CH-FR key [10]. There exist two
tuning modes: by channel or by frequency. To switch the tuning mode press the
