PROGRAMMING THE UC-202-IF to IF CONVERTER
R A N G E
1) IF PROCESSING
The IF processing system for distributing digital satellite signals
is specially developed for SMATV installations. This is the best
system for medium size (up to 150 outlets) and also for big
size SMATV installations (up to 1500 outlets).
The IF processing system is better quality than the multiswitch
system because it allows Automatic Frequency Control and
Automatic Gain Control. It is also better price for a number of
outlets bigger than 30.
With the IF processing system it is possible to distribute a
maximum of 30 transponders using only one coaxial cable
(about 240 TV programs). The RF terrestrial and modulated
channels can be multiplexed with these channels in the coaxial
cable, allowing the distribution of more than 300 channels. As
we are using only one coaxial cable it is easy to upgrade old
installation to the IF band. Usually, it is enough to change the
splitters, outlets, tap-offs and amplifiers.
This is the main system for digital SMATV installations in
2) ALCAD’S UC-202 SYSTEM
The UC-202 system allows implementing these kind of IF
It is very easy to program, only by introducing the following
- Input Frequency.
- Output Frequency
Every module of UC-202 can process two transponders. In the
case that both transponders are in the same polarity, the UC-
202 unit is needed, but in case that every transponder comes
in a different polarity, the UC-212 unit allows us processing
both of them in the same module.
The system is limited to 30 transponders because every digital
transponder needs 40 MHz for distribution (for a bandwith of
36 MHz). After processing 30 transponders there is no more
frequencies in the IF band (950 – 2.150 MHz). Those 30
transponders will fit in 15 modules and every power supply
(FA-203) can feed up to 8 modules of UC-202 and one IF
