Special Functions
The special functions menu contains some useful tools to qualify the SAT, TV or CATV
installation beyond signal reception. The content of this menu varies accordingly to which
has been the last measurement performed by the user: for instance, if the user performed
a SAT measurement, the special functions menu will display all the tools related to a satellite
installation; conversely, if the user performed a TV or CATV measurement, the special functions
menu will display (respectively) TV or CATV -related tools.
13.1. SAT Special Functions
The Satellite special functions let the user perform tests and measurements on particular dish
configuration such as Dual LNB, SCR or motorized dishes:
SAT SCR: The Satellite Channel Router (SCR) is a special LNB with typically 4 or 8 RF
outputs normally used in buildings centralized installations enabling the connection of up to 8
different receivers (decoders) to the same LNB. Each "User" (RF output) is assigned a specific
frequency to which the satellite channels will be down converted before being sent to the
receiver.
This test provides the user the ability to verify the correct signal reception for each one of the
LNB's RF outputs via the spectrum analyzer or the SAT measurement interface. In those
screens, the indication of the selected SCR user will be displayed.
