VSAT Application
Above Decks Powered - The LNB’s installed onto all VSAT antenna systems are powered by the antenna
itself (above decks), and thus there is no applicable use for VOLT control. For antenna systems that have
voltage and tone controlled multiband LNB’s installed, you will use the tracking band selection to
control/toggle the voltage output of the ADE 400MHz FSK modem. For detailed information, refer to the
“SETUP-Band Select” section of this document.
7.6.
SAT SKEW
SKEW is used to optimize the polarization of the feed to the desired satellite signal. In VSAT systems this is normally
adjusted during the cross-pol isolation testing with the Network or Satellite Provider (refer to (Optimizing Cross-Pol
Isolation).
7.7.
NID
In VSAT systems the Network Identification parameter should always be set to 0000 to allow external network lock to
be supplied into the ACU from the satellite modem.
