Satellite frequency

With input via the numeric keys

...

frequency input is in 5-figure form in

the range 10700 to 12747 MHz. With the

keys you can attain the optimum

receiving frequency by moving in 1 MHz steps (recommended if the picture is
grainy due to weak signals).

Polarisation/Orbit position

In these two menu entries, signal selection is carried out by the LNB supply voltage
and the 22 kHz switching signal, which is superimposed on the LNB supply volt-
age.

Polarisation

In the “Polarisation“ menu entry, the voltage level is used (14 or 18V) to set the
polarity (vertical or horizontal) and the 22 kHz switching signal to select the fre-
quency range (see table).

Orbit position

In the “Orbit Position” menu entry, the 22 kHz switching signal is used to switch
between two (or more) satellites for multifeed receiving systems (see following ta-
ble).

In the initial setup menu (submenu ”DiSEqC”), setting is carried out for the menu
entry the 22 kHz switching signal is operative for (polarisation or orbit position).

Note

With Astra satellites, only digital signals are transmitted in the upper frequency
band (high-band). Special receivers are also required, however (DVB receiver;
d-Box).
The customary (analogue) signals are transmitted on the lower frequency band
(low-band). The same is also true at the moment for Eutelsat programmes.

Select the required polarity therefore as either Vert. Low or Hor. Low only.

In the factory presetting (as delivered), the setting “Pos. A/B” has been chosen in
the “DiSEqC” initial setup menu, menu entry “22 kHz signal”.

The settings Vert. High and Hor. High are not operative.

Video deviation

The satellites transmit their signals with different video deviation, 16 or
25 MHz. The setting has an effect on the picture brightness.

Adjust the video deviation to obtain optimum picture brightness.

Oscillator

The receiver is equipped with four LO frequency groups (LO 1 to LO 4), which can
be set to give troublefree matching to different feed systems with different oscillator
frequencies (e.g. Telecom 1A).

In the delivered state, all four oscillator frequencies are set to 9.75 GHz
