During the whole process the instrument checks the state of the cable, the
connector and the LNB. Therefore, if it detects that the noise level is below a reference
level (standard value: 10 %), it will be shown the message “
LNB NOT DETECTED
“ at
the bottom of the screen. On the other hand, if the signal power is higher than the
threshold and the sound selection is enabled (refer to the configuration software
manual), the equipment will emit a variable frequency tone to help the user in order to
position the antenna and detect the maximum signal power.
If the LNB power supply voltage falls 1 V below the nominal value, the
instrument will show the message “
LNB SHORTCIRCUIT
“ and will temporarily switch
off the power supply to prevent overloads. After one second, the power supply will
switch on again, and it will check if the short circuit has disappeared.
This may occur due to a temporary fall in the voltage when connecting or
disconnecting the instrument from the rest of the installation. The message may also
appear when the power supply is overloaded because of using a LNB with excessive
consumption.
4.2.1 Satellite Detection and Location (1> DETECT)
This function is directly accessed on starting the instrument. If it is not the active
function, press key
[1] to select it.
The purpose of this function is to detect when the antenna is pointing at a
satellite (detection).
In order to do this, connect the instrument to the low-noise amplifier that is
located at the focus of the parabolic antenna. On the screen you will see two horizontal
bars that can vary depending on the power signal. The upper horizontal bar keeps the
maximum value measured during tracking. The lower horizontal bar shows the signal
power in real time. In addition to these bars, there is an audible signal that varies
depending on the power signal, from low tone (low power) to high tone (high power).
