The channel tuning allows the cursor to jump from channel to channel when
moving the joystick left or right or to jump to a specific channel of the
selected channel set.
The frequency tuning allows the cursor to move along the frequency band in
50 kHz steps, or to select a specific frequency.
► External power supply (available for terrestrial and satellite band)
It enables or disables the power supplied to external units such as
preamplifiers for antennas in terrestrial television or LNBs and FI simulators in
the case of satellite TV.
When this option is enabled the equipment applies at the output the voltage
selected by the user in the Supply Voltage option (see below). When this
option is disabled the equipment does not apply the voltage to the output but
it will behave as if it did.
► Supply voltages (available for terrestrial and satellite band)
It selects the voltage to be applied to an external unit.
Available voltage options change depending on the selected band.
Voltage available for terrestrial band is: External, 5 V, 12 V and 24 V.
Voltage available for satellite band is: External, 5 V (for devices working with
5 V such as GPS active antennas), 13 V, 13 V + 22 kHz, 18 V, 18 V + 22 kHz.
In the External supply voltage option the power supplier to the external units
is the power supplier of the antenna preamplifiers (terrestrial television) or the
satellite TV receiver (collective or domestic).
► LNB Drain (available for terrestrial and satellite band)
The LNB drain option shows the voltage and current flowing to the external
unit. If there is any problems (e.g. short circuit), an error message appears on
the screen ('SHORTCIRCUIT'), a warning beep sounds and the equipment will
not supply power. The equipment does not return to its normal operating state
until the problem is solved .During this time the equipment checks every three
seconds if there still the problem, warning with an audible signal.
The DRAIN LNB light indicator is lit if current is flowing to the external unit.
► LTE Filter (only available for terrestrial band)
It enables or disables the LTE filter (see 6.2 section: LTE Interference Test).
When the LTE filter is enabled an icon will appear at the top right of the
screen.
