Scan Mode Configuration - Promax 8 SE Manual De Instrucciones

USER'S MANUAL. PROMAX-8
To change the tune, press again the rotary knob [9]. The field Channel will be
activated again. Turning the rotary knob will be possible to change its value.
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).
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-8
SE 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
PROMAX-8
cable to the
to 863 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).
In the SCAN operating mode, all channels are considered as analogue. When the
power of a digital channel is measured in this mode, the instrument does not
carry out the integration of the power values, but it just measures at the central
frequency of the digital channel. Then, the resulting value is not calibrated and is
6 or 7 dB lower than the measurement made in the CHANNEL-FREQUENCY mode,
which does the power integration.

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 tree parameters:
THRESHOLD, REFERENCE
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.
