If the consumption value exceeds 500 mA, the protection function will intervene to
disconnect the power supply and will emit an acoustic beep to avert the user.

4.13.1.1.
RF INPUT MENU:
When the instrument is set to RF measurement mode, the following will appear on the
screen:
⇒
MODE: There are two available modes for changing the LNB power supply
•
STEP: The voltage changes by the discreet values of 0, 5, 13, 15,18 V
and, if enabled, 24 V.
•
Continuous. The voltage can vary from 5 to 18 V (24 if enabled) in continuous
mode, at intervals of 0.2 V.
⇒
STEP: voltage step setting at LNB start up.
⇒
22 KHz: enables or disables the 22 KHz tone
⇒
AMPS: enables or disables the display of the current consumed by the LNB instead
of the power supply voltage.
⇒
24 V: enables or disables the 24 V step or else the range from 18 to 24 V.
⇒
AUTO-RESET: this function allows for the auto-reset mode to be configured for the
LNB’s power supply voltage.
⇒
NOTE: if no charge is connected, the voltage of the LNB could drop very slowly due to
the internal filter capacitors.
⇒
NOTE: for safety issues, if the instrument is in satellite band and the tuning moves
outside of the same, the LNB will be shut off.
⇒
OPTICAL: This menu item can be selected in order to enable (ON) or disable
(OFF) the power supply for an optical LNB. The power supply is output through
the RF input’s BNC connector. The voltage is automatically set at 13 V.
⇒
OPTICAL MENU: This menu item can be selected in order to select the
wavelength for measuring the signals distributed by means of fiber optics.
The available wavelengths are:
1310 nm
1490 nm
1550 nm

VOLT/AMP FUNCTION
The LNB button has a secondary “Volt/Amp” function: press the
2nd
and
Volt/Amp
buttons in order to display the voltage or the current consumed by the powered device.
