Turning the encoder CW or CCW, cycles through the submenu titles:

CONFIGURATION
4.4 MODULATOR functions.
At this menu level, the modulator parameters can be modified and customised to
the user's needs. When modifying any modulation parameter, changes became active
only when confirmed by pressing the encoder function. Instead, pressing the MENU key
allows us to cancel the change of option. Let's comment on each function.
HP TS Input: Selects the input used for providing a High Priority (HP)
Transport Stream (TS) to the COFDM modulator. Note that in non-hierarchical
transmissions, this is the only TS input to the modulator. Options are:
ASI1: Use TS provided at ASI1 input connector (rear panel).
ASI2: Use TS provided at ASI2 input connector (rear panel).
SPI: Use parallel TS provided by SPI connector (rear panel).
PRBS: Use internally generated PRBS data to generate TS test packets.
LP TS Input: Selects the input used for providing a Low Priority (LP)
Transport Stream (TS) to the COFDM modulator. Note that in non-hierarchical
transmissions, this input is not used. Options are:
ASI1: Use TS provided at ASI1 input connector (rear panel).
ASI2: Use TS provided at ASI2 input connector (rear panel).
SPI: Use parallel TS provided by SPI connector (rear panel).
PRBS: Use internally generated PRBS data to generate TS test packets.
BW: This option enables output channel bandwidth selection. The COFDM
signal can be generated with a BW of 6 MHz, 7 MHz and 8 MHz.
8 MHz: selects an 8 MHz bandwidth.
7 MHz: selects a 7 MHz bandwidth.
6 MHz: selects a 6 MHz bandwidth.
