Setting up the TS Input,
9. Enter the Forward Error Correction (FEC) inner code rate. The FEC rate must
match the FEC of the transmitted signal. You can select 1/2, 2/3, 3/4, 5/6, 7/8
or Auto.
10. Set the input signal spectrum inversion setting (IQ), which allows the operator
to track and select inverted and non-inverted digital signals.
When set to Auto, received digital signals are tracked and inverted for correct
selection, as required. When set to Inv (inverted), the received digital signal is
always inverted. Conversely, when set to NonInv (non-inverted), the received
digital signal is never inverted.
11. Select the Roll Off factor of the incoming signal (.20, .25, .35). Set the value to .20
or .35 when DVB-S modulation is used, and either of the three when DVB-S2 is
used. Use a small number to reject or filter carriers close to the same frequency.
12. For RF1, RF2, RF3, and/or RF4, enter the Local Oscillator frequency #1 (LO1),
which sets the satellite antenna LNB local oscillator #1 frequency. You can enter
a value in a range from 0.0 to 15.0 GHz. This value must be lower than the value
for LO2.
13. For RF1, RF2, RF3, and/or RF4, enter the Local Oscillator frequency #2 (LO2),
which sets the satellite antenna LNB local oscillator #2 frequency. This option is
only used in dual-band LNB applications. You can enter a value in a range from
0.0 to 15.0 GHz. This value must be higher than the value for LO1. In single-
band LNB applications, set this value to 0.0.
14. Enter the Cross Over frequency for RF1, RF2, RF3, and/or RF4. This is an
internal threshold frequency used for selecting the LO1 or LO2 frequency,
depending on the current downlink frequency settings. This option is only used
in dual-band LNB applications.
You can enter a value in a range from 0.0 to 15.0 GHz. In a single-band LNB
applications, set this value to 0.0.
15. Set the Orbital Position for RF1, RF2, RF3, and/or RF4, in degrees. This is the
location in orbit of the satellite currently being used. The satellite position (in
degrees) in combination with the direction (either E (East) or W (West)) denotes
the satellite position the dish connected to the current RF Input should point.
This is used when the satellite is not available in the look-up menu list.
For manual configuration, enter the location of the satellite using the numerical
keypad. The receiver will not recognize the satellite name and identify it as
Unknown. This setting is required to resolve any ambiguity between RF inputs
during automatic disaster recovery.
