Satellite – Modulation Type Option
To access the Modulation Type option, press the Modulation Type softkey
in the
Service Info Menu
. This enables the type of modulation used by
the satellite transponder to be specified. This is included in the SI/NIT if
the Modulator output format is set to baseband (see the Output Format
option on the Setup/Modulator Menu).
If the Modulator output format is set to IF, then this option setting is
ignored and the modulation type included in the NIT is that specified by
the
Modulation
option on the
Setup/Modulator Menu
.
Use the + and –softkeys to scroll through the various options and then
press the Enter softkey after selecting one of them.

Satellite – FEC Rate Option
To access the FEC Rate option, press the FEC Rate softkey in the
Service
Info Menu
. This enables the FEC rate used by the satellite transponder to
be specified. This is included in the SI/NIT if the Modulator output format
is set to baseband (see the
Output Format
option on the
Setup/Modulator Menu
).
If the Modulator output format is set to IF, then this option setting is
ignored and the FEC rate included in the NIT is that specified by the
FEC

option on the
Setup/Modulator Menu
.
Use the + and – softkeys to scroll through the various options and then
