6.2.2.6. FEC Rate
The FEC Rate menu enables to set the Forward Error Correction rate according to the FEC
rate of the transmitted signal. The following figure illustrates the FEC Rate screen.

6.2.2.7. Spectral Inversion
The Spectral Inversion parameter sets the spectral mode of operation. This parameter is
configured according to the information provided from the broadcast head-end or can be set
to automatic. When set to automatic mode, the ProView 2900 tries the two spectral modes
until obtaining synchronization.
The following figure illustrates the Spectral Inversion screen.
