BOARD PLUG-IN ek-unm/2

“TRANSMODEM”

DVB-S /DVB-T/DVB-H

The board EK-UNM/2 allows a versatility without
precedents in the connection point to point in fact
Features
allows to modulate/demodulate signals on quadrature
single carrier and also on OFDM.  Modulation: QPSK -
The more innovative feature of this board is the
possibility to use different types of modulation in 16/32/64/128QAM -
reception and transmission, like for example receive a COFDM
DVB-S signal from satellite and transmit the same or  DVB-ASI Input / Output
 E3 Input /Output
other signals with DVB-T/H mode.  IF 70MHz Input / Output
When used in DVB-S configuration allows to carry,
further than E3 signals, also of transport stream (TS)  DVB-S / DVB-T
with Bit-rate up to 155 Mbit/s using constellations from  6/7/8 MHz channel

The settings allows a lot of configuration about  Viterbi rate

modulation's parameters, for example the symbol rate is  Reed Solomon
selectable to steps of 100 Kbit/s from 1 to 32 MSym/s.  Very good MER
The board allows to manage also an aggregate signal for

It is also possible a commutation between the internal  Digital Microwave Links
