Polytron SCA 32 fix User Manual
The right signal is well received by everyone.
Ultra compact single cable solution for 2 applications
Application 1: Mini headend for up to 32 transponders
POLYTRON’s SCA 32 fix creates a new SAT IF layer according to your demands.
SCA 32 fix puts the desired SAT transponders out of the origin frequency into a new frequency. The result is a new SAT
IF layer with up to 32 transponders which can be distributed
via a single coax cable to an unlimited number of subscribers.
SCA 32 fix’s functional
principle
Up to 32 digital SAT transponders out
of 4 polarisations are put into a new
frequency so that only the desired
transponders can be received.
Programming with PC software.
