2. PRODUCT DESCRIPTION
Compact IF-IF unit with SCD2 (dCSS) technology of the Multiswitch series, suitable for DVB-S and DVB-S2 SAT signals. SCD2-
32IF is equipped with 32 independent digital fi ltering and conversion blocks; each block can amplify and translate a DVB-S/S2
in frequency received by one of the four independent inputs in the 250-2350MHz band, compatible with wide-band system too,
and can produce it on one of the two independent outputs in the 950-2150MHz.
The system is equipped with an AGC (Automatic Gain Control); therefore, the output level of each transponder is kept constant
to the set level (78÷86dBuV) even when the input level changes (from 55dBuV to 85dBuV).
The system can also be used in isofrequency, whichh means the converter can be used as a fi lter by setting the same frequency
value in the input and output. It allows the maximum fl exibility; each conversion block can be used either in Fixed mode (IF-IF)
or Dynamic mode (control from STB by DiSEqC controls from the SCR EN50494 or SCD2 EN50607 decoders). The unit can also
offer, in IF-IF mode, 28 transponders of Sky and TivùSat while simultaneously in SCD2 mode carrying the signal of 4 user-bands
to 2 PWR MySky HD decoders. On SCD2-32IF SSA product (with only one output) it is possible to adjust SAT gain (20dB) and
slope (15dB) with product trimmers; additionally it is possible to adjust SAT tilt (8dB) using PC software; this product has also
higher output level (127dBµV). The product is equipped with:
• Two power supply connectors to allow a redundant power supply.
• Four independent inputs with remote power supply that can be enabled by software.
• Monitoring LED.
• USB port to program, save/restore the confi guration.
Programming is carried out from the PC by a USB cable and a proper software that can be downloaded from the website www.
fracarro.it; the software defi nes the input and output frequencies and other confi guration parameters of the headend (level,
tilt, …); it is possible to assign a slope to the generated signal (up to 8dB) to compensate the loss of cables in the distribution.
