Figure 13.- SCAN configuration menu.
Figure 12.- SCAN mode, power
detection function.
In the case of having activated the
broadband power detection function (POWER
MEAS ->
∑
PWR) in the configuration menu of
SCAN mode (See section 4.2.2.1), on the display
of PROMAX-10
Premium
will appear the total
power level on the instrument RF input. See the
attached figure.
This parameter indicates the total power that
is being transmitted by the connected coaxial cable
to the PROMAX-10
Premium
in the band from 5 to 862 MHz.
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 three parameters:
THRESHOLD, REFERENCE LINE and POWER
MEASUREMENT. 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.
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
862 MHz (
∑
PWR).
