Spaun SBK 5503 NFI 842488 User Manual

•  Synchronous level adjuster for each
 

SAT IF system

•  A special amplifier / filter design improves the 
 

intermodulation properties of the launch amplifier

 considerably
•  The high selective input filter guarantees that  

interference products of the LNBs cannot drive

 

the amplifiers into saturation

•  An additional output filter ensures that intermodulation

 

products and noise effects do not degrade the

 

terrestrial signal

•  The terrestrial input is passive and return path
 

compatible with the possibility of a 18 V (250 mA) remote   

 

current in both directions for an amplifier. 

•  Selective standby function:
 

If all subscribers only watch TV programms of SAT system  

A, only the appropriate LNB is supplied with power. The  

internal logic turns off the power supply of all other LNBs as

 

well as that of the integrated amplifiers.

 

This process results in significant energy savings!
