Configuration - Fracarro D-Matrix 8T Instructions D'emploi

-
OUTPUT MENU: allow to setup the D-MATRIX 8T digital output signal.
-Output signal DVB standard:
-
MUX 1, MUX 2, MUX 3, MUX 4, MUX5, MUX6, MUX7 and MUX8: allows to select the output
MUX configuration.
CONFIGURATION: sets all the output MUX parameters.
MODE: enable/disable the selected output MUX; if it is set on OFF, the MUX is switched off.
The output multiplexes are gathered in two groups of four multiplex each (QUAD). For each group it can
be chosen different operating mode: SINGLE (one single modulator switched on), TWIN (two modula
tors switched on) or QUAD (all the four active modulators).
The same working mode is valid for the second group of modulators comprising of the MUX5, MUX6,
MUX7 and MUX8
CHANNEL OUT:
CHANNEL OUT: tto set the RF output channel; this parameter modifies automatically the chan
nel value of the adjacent belonging to in the same group multiplexes. Example: if the MUX 1 output
channel is E21, the MUX 2, 3 and 4 will be respectively remodulated in the channels E22, E23 and
E24.
COUNTRY: Select the country;
OUTPUT FREQ.:
FREQUENCY (MHz): to set the RF output frequency where the MUX will be modulated; this pa
rameter modifies automatically the frequency value of the adjacent MUX belonging to the same
group;
CH BANDWIDTH: to set the output channel bandwidth from the available ones (7 MHz, 8 MHz,
6MHz); this parameter modifies automatically the bandwidth value of the adjacent MUX in the same
group.
FEC: to set the FEC (Forward Error Correction) parameter from the available ones (1/2 ,2/3, 3/4, 5/6,7/8);
GUARD INTERVAL: to set the guard interval value from the available ones (1/4,1/8,1/16,1/32);
CARRIERS NUM: View the number of carriers of the DVB-T output signal (only 2K).
COSTELLATION: to set the constellation used to modulate the carriers as 16QAM, 64QAM and QPSK;
OUTPUT FLOW CHART
the DVB output signal standard is DVB-T (2K).
