1. Product description
1.1.
General
The SKF 40-00 module transmodulates 8PSK/QPSK modulated transponders into FM. The quattro module
features four fully independent input tuners. The transmodulated FM output signals are routed to one RF
output.
1.2.
Scope of delivery
1 × SKF 40-00 8PSK/QPSK | FM quattro module
1 × DC connection cable
1 × Quick start guide
Note.
The power supply unit and the basic unit are not included in the scope of delivery of the module
.
They
are available as an option.
1.3.
Inputs/tuners
The SKF 40-00 includes four independent DVB-S/S2 tuners.
Connection to the LNBs
On the SAT-IF input the headend modules have a remote supply voltage for the LNB and use DiSEqC 1.0
functionalities. Therefore, they can be connected directly to the LNB.
Multiswitches as input distributors
Optionally, you can also use multiswitches as input distributors. The advantage of this solution is that you can
set both the SAT IF level and the satellite via the user interface. Changes in the list of programmmes can be
made using remote maintenance, so that it is not necessary to change or modify the input distribution on site.
Demodulation
The selection of the transponder and the demodulation of the QPSK/8PSK modulated signal are both made in
the tuners.
The prepared data flow is passed on to the modulators.
1.4.
Output/modulators
The
SKF 40-00
has 16 FM output modulators.
The output frequencies can be choosen between 87,5-108 MHz. A minimum distance of 0,3 MHz between the
FM carriers has to be maintained.
1.5.
Graphical user interface
The settings of the modules can be changed via the user interface of the integrated web interface. To access
the user interface and thus configure the devices, you need a standard PC/laptop with a network interface and
the actual version of the installed web browser.
