Input the LNB type. -
The XLV Ex can tune directly frequencies within the 9.50 to 21.50 GHz range. If you know the
frequency on the coaxial cable, also known as L-band frequency, select LNB types ‘
None
’.
If you do not know the L-band frequency, you need to input the frequency of the selected
satellite transponder and the frequency used by the local oscillator (L.O.) of the LNB in your
antenna system. Select LNB type ‘
Single
’ and input the L.O. frequency in the ‘Low’ field, or
‘
Dual
’ and input both the low and high frequencies. Frequencies must be entered in GHz.
Note:
Use
the high frequency parameter only when a dual
LNB is employed.
4.
Input the satellite frequency in GHz in the ‘Frequency’ field under the Tuner Parameters
heading.
5.
Input the symbol rate in KSym/s.
6.
Select the polarization of the satellite feed (either Vertical/Right or Horizontal/Left).
7.
If the LNB type is set to ‘None’, you can control the 22 KHz switch. Select ‘Off-Low LNB’ to
set the local oscillator of the LNB to its low frequency and ‘On-High LNB’ to set the local
oscillator to its high frequency.
