Spaun SBK 5503 NFI 842488 User Manual

The UniSystem multiswitches can be used as stand-alone 
devices or can be cascaded with themselves for an easy 
extension of the number of subscribers. The UniSystem is 
extendable to up to 16 SAT IF levels.

•  After the SAT IF signal has been decoupled
 

by microstripline directional couplers, it is 

 

amplified for each receiver output, which 

 

produces a tap loss of 3 ... +1 dB

SMS 9989 U, SMS 9987 U

Each receiver output has an 
integrated switchable level shifting 
(except SMS 9987 U)

9 DC-decoupled terminating resistors 
are shipped with the SBK 131309 NF to 
terminate the trunk lines.

1.   As a single multiswitch for 8 SAT IF signals
2.  In „piggyback“ mode in conjunction with a
 

multiswitch relay extensible for 16 SAT IF signals. The  

 

wall mounting frame supplied is designed to support  

 

also the „piggyback“ assembly 

3. The master outputs also facilitate cascading, so 
 

that the number of receivers can be increased. 

 

Without amplifying the signal, it is possible  

 

(depending on cable quality and length) to feed up  

 

to 24 receiver
