3.5.2 CONV CFG
The item “CONV CFG” in the main menu allows access to the configuration of the
main operational parame-
ters of the converter. This menu point is not shown if the REMOTE/LOCAL feature is enabled and if the unit is
in REMOTE mode. After this menu item was selected with the left or right arrow keys the items of the sub-
menu belonging to
this main menu item can be activated by pressing the “Enter” key. The items of this su
b-
menu are explained in the following:
3.5.2.1 CHANNEL x CFG
The item “CHANNEL x CFG” is only available for dual channel devices. This menu point contains the
“FREQENCY”, “ATTENUATION” and “EQUALIZATION”
menu items for each channel.
3.5.2.2 FREQUENCY
The item “RF FREQUENCY” in the “CONV CFG” submenu allows the configuration of the RF
output frequen-
cy of the Upconverter. The range of this parameter depends on the converter type (C, X, Ku, K) and can be
seen from Figure 4. In case of a multi band Upconverter, the band is selected by entering a suitable frequen-
cy.
With
dual channel devices, this menu point can be found in the “CHANNEL x CFG” submenu for each cha
n-
nel.
Note: For devices with 720 MHz IF frequency the RF center frequency of a 400 MHz band is set. Therefore
the adjustable frequency range is smaller then the usable frequency range. This is shown in Figure 13.

3.5.2.3 ATTENUATION
The item “ATTENUATION” in the “CONV CFG” submenu allows the configuration of the attenuation of
the
converter unit. The maximum conversion gain (typically 40 dB) is reduced by this attenuation value. The
range of this setting is 00.0 dB to +30.0 dB in 0.1 dB steps.
With
dual channel devices, this menu point can be found in the “CHANNEL x CFG” submenu for each cha
n-
nel.
Example:
Attenuation = 0 dB:
Overall conversion gain = 40 dB
Attenuation = 15 dB:
Overall conversion gain = 25 dB
Attenuation = 30 dB:
Overall conversion gain = 10 dB
3.5.2.4 SIGNAL OUTPUT
The item “SIGNAL OUTPUT" in the “CONV CFG” submenu allows to enable or disable the converter signal
path. If the signal path is enabled
and no alarm or warning condition is active to suppress the signal, the “
TX
On” LED is green. If the signal path is enabled and an alarm or warning condition is active, so that the signal
path is currently not on, the “
TX
On” LED is yellow. If the signal
path is dis
abled the “
TX
On” LED is off.
