Satellite frequency, Polarisation/Orbit position

Programming TV programmes

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).

Frequency range	Polarisation	LNB voltage	Switching	Setting
			signal, 22 kHz
10.7-11.7 GHz	vertical	14 V	Off	Vert. Low
	horizontal	18 V	Off	Hor. Low

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).

	Satellite	Orbit position	22 kHz switching
			signal

	Astra 19.2° east	1	Off
	Eutelsat 13° east	2	On
	Eutelsat 10° east	3	Off
	Eutelsat 16° east	4	On
	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
