Setup – Satellite Configuration
6012-12W Installation Manual
be selected, remotely or by the user onboard. The satellite selection will in turn control the hardware on the
antenna pedestal to select the correct TX & RX hardware and the correct tracking settings.
Sea Tel provides quad-band LNBs as standard on the Series 12 Ku-Band antennas.
1.
Access the Satellite Configuration screen.
2.
If no satellites have been configured, or
you need to add another, click Add
Satellite.
3.
Enter a name for this satellite you are
creating.
4.
Enter the Longitude position of this
satellite.
5.
Select the satellite that your airtime
services will be provided on.
6.
Determining the IF Tracking Frequency (MHz)
The IF Tracking frequency parameter is a value entered into the MXP MHZ Sub-Menu. The
value itself may be provided by your air-time provider and the MHz value will be entered
directly in this sub-menu.
Or, the RF downlink frequency of a specific carrier on the desired satellite can be obtained from
a satellite website and calculated by using the formula RF- LO = IF. When you take the Satellite
Transponder Downlink RF value and subtract the LNB’s Local Oscillator (LO) Value, the
resultant value will equal the Intermediate Frequency (IF). It is this IF value that will be entered
into the MXP for tracking purposes. The MHz and KHz are entered as a single value.
Example: Assuming an LNB LO value of 11.25GHz: We want to track a satellite downlink
carrier at 12268.250 MHz.
12268.250 MHz – 11250.000 MHz = 1018.250 MHz IF
7.
Enter the entire six digits of the
“megahertz and kilohertz” is simply
entered as one value in the Frequency
field.
8.
SAT SKEW
SKEW is used to optimize the polarization of the feed to the desired satellite signal. It is
entered when a known satellite is skewed. Use Polang to peak the polarity.
9.
Enter the known skew for this satellite in
degrees, leave at zero if this satellite is
not skewed.
