SPECTRAL INVERSION
The Spectral Inversion parameter sets the spectral mode of operation. This
parameter is configured according to the information provided from the
broadcast head-end or can be set to automatic.
When set to automatic mode, the PVR 6000 tries the two spectral modes until
obtaining synchronization.
Spectral Inversion
1 AUTOMATIC
2 INVERTED
3{ NORMAL
The available options are:
• AUTOMATIC – Automatically selects between Normal and Inverted spectral
mode
• INVERTED – Inverted spectral mode
• NORMAL – Normal spectral mode
LNB POWER SUPPLY
The PVR 6000 sets the polarization of the receiving antenna by providing
different voltage levels to the LNB, 13v for vertical polarization and 18v for
horizontal polarization.
The polarization of the receiving antenna is determined according to the polarity
of the satellite transponder.
LNB Power Supply
1{ 13V (VERTICAL)
2 18V (HORIZONTAL)
3{ OFF
The available options are:
• OFF - No voltage is supplied to the LNB. Use this option either when
cascading IRDs using the loop-through connector on the L-Band interface or
when this voltage is supplied to the LNB by external source.
• 13V (VERTICAL) – Vertical polarization
• 18V (HORIZONTAL) – Horizontal polarization
