Table 11.3.1: 8VSB Modulator MPEG Selection Set Up Screen (BTD/BRD)
This screen allows the user to select between an internal or external source in
the 8 VSB modulator. During the installation of the system, an off air signal
may not be available to the modulator, therefore the user can set the source to
INTERNAL to generate an 8 VSB signal inside the tray that can be used for set
up. Once the Receive Signal is available, the source must be set to EXTERNAL.
Table 11.3.2: 8VSB Modulator Linear Equalization Selection Screen (BTD/BRD)
This screen controls the operation of the linear equalizer. When set to ON, the
modulator applies linear correction to the IF output. When set to OFF, no
correction is applied to the IF.
Table 11.3.3: 8VSB Modulator Non Linear Equalization Selection Screen
(BTD/BRD)
This screen controls the operation of the non linear equalizer. When set to ON,
the modulator applies non linear correction to the IF output. When set to OFF,
no correction is applied to the IF.
