Dvb-S/S2 (Qpsk/8Psk) Digital Channel Configuration - Promax TV EXPLORER HD Manual De Usuario

USER'S MANUAL. TV EXPLORER HD
This configuration menu shows, besides the user definable COFDM signal
parameters, the value of the rest of signal parameters detected automatically:
Code Rate Also known as Viterbi ratio, defines the ratio between the data bits
number and the total number of bits transmitted (the difference
corresponds to the number of control bits for the error detection and
recovery).
Modulations Carriers modulation. It also defines the system noise immunity.
(QPSK, 16-QAM and 64-QAM).
Hierarchy The DVB-T/H norm contemplates the possibility to make a TDT
transmission with hierarchical levels, it is to say a simultaneous
transmission of the same program with different image qualities and
noise protection levels, in order the receiver can exchange to a
signal of smaller quality when the reception conditions are not
optimal.
Cell ID Cell identifier. Shows the transmissor identification code.

5.12.3 DVB-S/S2 (QPSK/8PSK) Digital Channel Configuration

Press the Measurements Configuration
CONFIGURATION menu and turn the rotary selector [1] to access the QPSK/8PSK
signals parameters which can be defined by user and are described below:
1) Channel BW (channel bandwidth)
Enables the channel bandwidth to be selected over a range from 1.3 MHz to
60.75 MHz. The selection of this parameter is essential for the correct operation of
the tuner, as it affects the frequency separation of the carriers.
