Table 3.4: IF Power Settings
Available Settings Description and Notes
Normal Normal IF power level. If the low and user settings are the same as the
normal setting, then only the normal setting is available.
Low
Low IF power level. This setting is not available if it is equal to the normal
setting.
The IF power is automatically set to the low setting (or the normal setting, if
the low and normal settings are set to the same level) if the IF output is
switched off, but it is not automatically set back to its previous setting when
the IF output is switched back on.
User User-defined IF power level. This setting is only available if the IF Power
option is set to a level different to the normal or low settings.
3.6.5 FEC Rate Option
Considerations
Changing the modulator convolutional FEC rate affects the automatic
symbol rate, video bit-rate and video resolution calculations as shown by
the equations on page 3-23. The available settings are: 1/2, 2/3, 3/4, 5/6,
7/8 and 8/9.
Pressing the FEC Rate softkey cycles the FEC rate through the available
settings.
The FEC rate is locked (fixed) when both the IF Output and Modulation
options are set to On. One (or both) of these options must be set to Off in
order to change the FEC rate.
Modulation and IF Output Switched On
The screen shown below is displayed. In order to change the FEC rate,
modulation must first be switched off. Press the Yes softkey to do this
automatically (and proceed to the next screen), or press the No (or Quit)
softkey to return to the menu.

new value using the keypad. Press the Enter softkey to accept the new
value.
