Multi-channel radio relay
The new solution is to build a multi-channel radio relay to transmit the video signal and sound.
This solution can be seen as a continuation of RRL Studio-3, but gives the customer greater
flexibility in the configuration it requires, and the possibility of a rapid modernization of the
system. The new approach also improves the reliability of the system as a whole.Basis for
the solution to this system is the principle of block construction.
                                     MPEG2  SDI/CVBS Encoder 
1. 2 channels CVBS / SDI MPEG2, has 2 analog inputs and 2 composite inputs SDI. Output ASI.
Or may be similar in function Single Encoder Standard MPEG4/AVC in case you want to transfer
HD signals.Sound in the SDI can be embedded as well as analog. The flow rate for each channel
adjustable to 15000kBit/sek.
                                              Modulator 4ASI/DVB-S(S2)
2.Modulator 4ASI/DVB-S (S2), representing a modulator of the standard DVB-S (S2) with four ASI
input and output IF standard DVB-S (S2). Output signal frequency can be set to 70 or 140 MHz
or L band within 950-1570 MHz. Also available are versions with a bandwidth of 200 MHz tuning
range 950-2050 MHz, or a full range of adjustment.
                                               BUC Pout=400 mW

                                            BUC + Injector Pout=1W

3.BUC - outdoor unit step-up converter for converting the input standard, DVB-S (S2) in the desired
range of frequencies and it increased to the desired level. Heterodyne transmitter is built in PLL
circuit with a reference frequency of 10MHz. Linear power output of 20 to 1 watt. Powered BUC
from the modulator or by a separate injector, depending on required capacity.

4.Receiver DVB-S (S2) - Receiver standard DVB-S (S2) equipped with 2 ASI outputs and a single
IP access. This receiver can be both our production and third party products of different price range.

All units have control on the input Ethernet (except BUC), providing possible to configure and control.
Just on this output can exercise control of the video, as well as the transmission of signals on
optics as a backup or third video to consumers.

External power BUC has a remote control from the modulator allows you to monitor the parameters
of BUC - local oscillator frequency, power level, the presence of an input signal. It is possible to
remotely change the threshold of the AGC and the value of the heterodyne frequency.
Structurally lower part of the transmission may consist of separate blocks-factor 1U,
or may be installed in a constructive cubblokov 3U.

                                                     Technical parameters:

     Frequency range                                 :             7 - 8 10.7 - 11.2, 11, 7 - 12,5 GHz
     Linear power output of                        :             20 mW to 1 W
     Input frequency range                        :             70-140 или 950 — 2050 МГц
     Supported modulation types                :             QPSK, 8PSK (DVB-S, DVB-S2)
     Heterodyne                                         :              PLL
